Persistent memory for AI coding agents.
Your AI coding agent learns your codebase the way a senior engineer would — what files go together, what you usually edit next, what patterns matter. The memory persists across sessions and surfaces automatically. No MCP tool call required: NeuralMind writes a
SYNAPSE_MEMORY.mdfile that Claude Code loads on every session start, so the agent boots with what it's learned about your code already in context.
Works with Claude Code, Cursor, Cline, Continue, and any MCP-compatible agent. 100% local — your code never leaves your machine. (Side effect: ~5–10× cheaper agent sessions because the agent stops re-loading context it already understood. Benchmarks below ↓.)
🆕 New in v0.24.0 — memory namespaces & branch isolation. The learned synapse layer is now namespace-aware:
branch:<name>/personal/shared/ephemeralmemory live separately in the same store, so a feature-branch spike can't pollute what the agent learned aboutmain. Recall stays smart by default — a transparent merged view weights the active branch at 1.0×, your long-termpersonalmemory at 0.8×, and an importedsharedteam baseline at 0.5× (published constants, attributed per-namespace inquery --trace). Newneuralmind memory {inspect,reset,export,import}shows contribution by namespace, clears exactly one namespace, and moves memory as versioned JSON bundles (the PRD 8 team-memory on-ramp). Existing learned memory migrates in place, losslessly intopersonal— single-transaction rebuild, rollback on any failure, proven by a no-data-loss test. Release notesv0.23.0 — versioned index contract (IR), retrieval-quality harness, debug traces, and a local daemon. Four future-proofing foundations. (PRD 1) A canonical, schema-versioned intermediate representation of your code graph, validated on every build — a new
neuralmind validatecommand checks the contract without a vector backend; the embedder still readsgraph.jsonunchanged (the IR round-trips back identically), so retrieval is unaffected. (PRD 2) A newneuralmind benchmark --qualitymode measures whether retrieval finds the right code — precision@k / recall@k / MRR / answerability over 30 golden queries across Python/TS/Go — and fails CI on a regression. (PRD 3)neuralmind query --traceshows why a result came back — per-layer candidates, cluster scoring with vector-vs-synapse attribution, and final hits. (PRD 5) An experimentalneuralmind daemonholds project state warm so repeatquery/statsskip cold backend init (auto-preferred when running, transparent direct-mode fallback). Release notesv0.22.0 — turbovec becomes the default (when available).
import neuralmindno longer requires ChromaDB, and the default backend is nowauto: prefer the ChromaDB-freeturbovecpath when its deps are installed, else fall back to chroma. Safe by construction — a plainpip install neuralmindis unchanged; only installs with the[turbovec]extra flip, with a one-time auto-reindex (the old ChromaDB index is left as a fallback, nothing deleted).neuralmind doctornow shows the resolved backend. The staged middle step toward retiring ChromaDB. Release notesv0.21.0 — ChromaDB-free retrieval. NeuralMind can now embed and search with zero ChromaDB: the opt-in
turbovecbackend pairs Google Research's TurboQuant compressed index (8–16× smaller vectors) with a bundledOnnxMiniLMEmbedderthat produces vectors byte-identical to ChromaDB's (all-MiniLM-L6-v2on just onnxruntime + tokenizers). At/above retrieval parity on the gold set (fact-recall 0.744→0.800). Enable withbackend: turbovecinneuralmind-backend.yaml. This retires the dependency behind the recurring CVE-2026-45829 advisory. Release notesv0.20.0 — Measure the onboarding lift.
neuralmind eval --onboardingturns NeuralMind's headline differentiator into a number: does an agent that inherits a committed team memory retrieve better on its first queries than a cold agent with none? The headline is the top-k module hit-rate lift (a deterministic +6.5 points on the reference fixture), with fact-recall + grounding as honest secondaries; budget-neutral by design, gated in CI at lift ≥ 0. Release notesv0.19.0 — One-command MCP setup.
neuralmind install-mcp --allauto-detects your installed agents — Claude Code, Cursor, Cline, Claude Desktop — and registers NeuralMind's MCP server with each (non-destructive merge, idempotent). The agent then onboards onto your codebase through NeuralMind's tools instead of grepping cold. Distribution is half the moat; the learned synapse layer (usage memory) is the other half. Release notesv0.18.0 — Incremental updates. Re-index just the file you edited, not the whole repo:
neuralmind watch --reindexre-parses each changed file and re-embeds only its nodes (unchanged files stay byte-for-byte identical, so the embedder skips them). Your index stays fresh as you type. Release notesv0.17.0 — Optional SCIP precision. Set
NEURALMIND_PRECISION=1with a SCIP index (scip-python/scip-typescript/scip-go) and NeuralMind folds in compiler-accuratecalls/inheritsedges, replacing the heuristic ones for covered files. Off by default, dependency-free, proven by a precision check in the CI gate. Release notesv0.16.0 — Multi-language: TypeScript + Go. The built-in tree-sitter backend now indexes Python, TypeScript, and Go out of the box —
neuralmind build .works standalone on a TS or Go repo, no graphify. Proven at parity per language by the CI gate (100% symbol coverage vs graphify). Release notesv0.15.0 — No graphify needed. A built-in tree-sitter graph backend, so
pip install neuralmind && neuralmind build .just works — no second, external tool. graphify still takes priority where present. Proven at parity by a CI gate (reduction + faithfulness within tolerance). Release notesv0.14.0 — Measure faithfulness. A new contributor/CI command —
neuralmind eval— turns "does the memory actually help?" into a number: it scores whether NeuralMind's selected context contains more of the facts a correct answer needs than a naive baseline at the same token budget (a faithfulness delta, plus grounding and contradiction checks). 100% local by default; the LLM-as-judge is opt-in. Release notesv0.13.0 — Measurement foundation. The offline faithfulness dataset + expected-fact-recall scorer and polyglot (TypeScript + Go) retrieval fixtures that
neuralmind evalis built on. Release notesv0.12.0 — Install Doctor. One command —
neuralmind doctor— inspects your setup (code graph, semantic index, synapse memory, MCP server, Claude Code hooks, query-memory consent) and prints each piece with a status and the exact command to fix it. Exits non-zero on a real failure so you can gate CI or an agent's setup step on it;--jsongives a stable machine-readable snapshot. Release notesv0.11.0 — Directional Synapses. The brain-like layer now learns what comes next, not just what goes together. A new
synapse_transitionstable records ordered(from_node, to_node)observations every time the watcher flushes a batch, so the agent can askneuralmind next <file>(or call theneuralmind_next_likelyMCP tool) and get a probability distribution over what's typically edited after that file. Additive — the existing undirected synapse graph keeps doing its job. Release notesv0.9.0 — Enterprise-Ready. GHCR auto-built multi-platform container image (
docker pull ghcr.io/dfrostar/neuralmind:latest), CycloneDX SBOM attached to every release, air-gapped install walkthrough, and a compliance one-pager consolidating NIST AI RMF + SOC 2 + GDPR claims. Release notesv0.8.0 — Always-On.

Three concrete behaviors appear once the synapse layer has watched a few coding sessions on your project. None of them require the agent to call extra tools — the memory primes the model on session start and surfaces predictions automatically.
| Without NeuralMind | With NeuralMind |
|---|---|
| Every session, the agent starts cold. You re-explain your auth flow, your billing module, your naming convention. | Session starts with SYNAPSE_MEMORY.md already in context: "strongest associations: middleware.py ↔ handlers.py ↔ session.py — auth flow. Hub: middleware.py." The agent boots knowing the shape of your code. |
Agent finishes editing payment_service.py, asks "anything else?" |
Agent: "after payment_service.py you usually update webhook_handler.py (45%) and the test file (28%) — want me to do those too?" Learned from your edit history, no manual hint needed. (v0.11.0+) |
npm test floods the conversation with 800 lines. Agent re-reads 50K tokens. |
Hook auto-summarizes Bash output to errors + repeated-line patterns + last 3 lines. neuralmind last recovers the raw cache when needed. (v0.10.0+) |
The brain layer learns continuously from how you actually work — file co-edits via a watcher daemon, query intent from MCP calls, tool-use patterns from PostToolUse hooks. Decays unused associations like a real brain so stale knowledge doesn't crowd out current patterns.
This is not "another RAG tool." It's the memory layer that everything else assumes the agent already has.
The clearest evidence the memory is working is the measurable side effect: the agent stops re-loading context it already understood. Reproduce it on a freshly cloned checkout:
git clone https://github.com/dfrostar/neuralmind && cd neuralmind
bash scripts/demo.shThe script creates an isolated venv, installs the deps, builds the index for the bundled fixture (tests/fixtures/sample_project/), and runs three real questions. Each question loads only the relevant code instead of the whole repo — exactly the kind of context-economy a senior engineer applies without thinking. Output looks like:
Q: How does authentication work in this codebase?
naive = 4,736 tok neuralmind = 829 tok reduction = 5.7×
Q: What are the main API endpoints?
naive = 4,736 tok neuralmind = 923 tok reduction = 5.1×
Q: Explain the billing flow from a user perspective.
naive = 4,736 tok neuralmind = 826 tok reduction = 5.7×
Average reduction: 5.5× across 3 queries
Avg context size: 859 tokens (vs 4,736 naive)
Est. monthly saved: ~$34.89 @ 100 queries/day on Claude 3.5 Sonnet
Wall time: 0.85s
The fixture is intentionally small (~500 lines) — it catches regressions in CI. Real repos consistently hit 40–70× on the same pipeline (benchmarks · community submissions · interactive dashboard). Once the demo convinces you, run it on your own code:
pip install neuralmind # built-in tree-sitter backend — no graphify needed (v0.15.0+)
cd /path/to/your-repo
neuralmind build .
neuralmind benchmark . --contributePrefer graphify's richer graph? Install it and it takes priority automatically:
pip install neuralmind graphifyy && graphify update . && neuralmind build .
Two docs you should read before forming an opinion. Both are linked from this section so you can pick what you need:
- docs/BUSINESS-CASE.md — the compelling pitch, with provable numbers. Every claim is a single command away from being verified on your own code. ROI math with assumptions you can change. Three concrete scenarios. Read this if you're evaluating whether to bring NeuralMind to your team.
- docs/HONEST-ASSESSMENT.md — the skeptic's companion. When NeuralMind isn't worth installing. What "40–70×" actually means (and doesn't). Where the community-benchmark sample is too small to extrapolate. Read this if you want to know what could go wrong before adopting.
The headline you can stand on: retrieval reduction is measured in CI on every commit (open any closed PR in the PR list — each one has a sticky benchmark comment with current numbers) and reproduces in 30 seconds on a fresh clone via bash scripts/demo.sh. Real-world repos have submitted 46–66× but n=2 — your number comes from neuralmind benchmark . --contribute on your code.
For enterprises and regulated industries:
- 100% Local Processing – Your code never leaves your machine. All embeddings are generated and stored locally using ChromaDB.
- No External APIs – NeuralMind runs completely offline. No cloud services, no telemetry, no data exfiltration.
- Explainable AI – Every context decision is auditable. Know exactly which code was retrieved (Extracted) vs. inferred by the model.
- Open-Source & MIT Licensed – Full transparency. No hidden clauses, no vendor lock-in. Audit the code yourself.
- GDPR/HIPAA-Friendly – Process sensitive code without compliance concerns. All data stays under your control.
For CTOs & Security Teams:
- ✅ Zero external dependencies for code storage
- ✅ Runs behind your firewall or on-premise
- ✅ No collection of usage metrics or code patterns
- ✅ Predictable, reproducible results (not a black box)
- ✅ Works with proprietary and sensitive code

If neuralmind install-hooks has been run for this project (check for .claude/settings.json), Claude Code automatically compresses tool outputs before you see them:
| Tool | What happens | Typical savings |
|---|---|---|
| Read | Raw source → graph skeleton (functions, rationales, call graph) | ~88% |
| Bash | Full output → error lines + warning lines + last 3 lines + summary | ~91% |
| Grep | Unlimited matches → capped at 25 + "N more hidden" pointer | varies |
This is fully automatic — you do not need to call any extra tools.
After every Bash call, NeuralMind appends a content-aware footer so the agent can tell at a glance what was dropped — not just how many bytes:
[neuralmind: dropped 23 lines (12 info, 8 debug, 3 other);
repeated: 5× 'Gamma API error 503' · 4298 B stdout total ·
`neuralmind last` for cached raw · NEURALMIND_BYPASS=1 to disable]
This lets the agent judge whether the dropped middle was log noise (safe to ignore) or a buried error (worth recovering). No second query needed to find out.
Every compressed Bash call also stashes its raw stdout/stderr to
<project>/.neuralmind/last_output.json (single-slot, 2 MB cap,
atomic writes). Recover it with:
neuralmind last # human-readable raw output
neuralmind last --json # full payload (ts, command, exit, stdout, stderr)This turns NEURALMIND_BYPASS=1 from a re-run-from-scratch cost
into a free lookup — meaningful on npm test (~28s),
non-deterministic API calls, or any destructive command that can't
be re-run safely.
To bypass compression on a future command (the new full output goes into the cache instead of being summarized):
NEURALMIND_BYPASS=1 <your command>To disable the recovery cache entirely:
export NEURALMIND_OUTPUT_CACHE=0After neuralmind watch has been running for a handful of sessions, the
synapse layer learns directional edit patterns — not just what files
go together but what file usually follows what. Ask it directly:
$ neuralmind next . src/auth/handlers.py
After src/auth/handlers.py:
45.2% tests/test_auth.py
28.4% src/auth/middleware.py
12.1% docs/auth.md
8.3% src/auth/__init__.py
6.0% src/main.pyThe same prediction is available three ways depending on who's asking:
| Surface | How an agent reaches it | Where it's read |
|---|---|---|
MCP tool neuralmind_next_likely |
Cursor / Cline / Continue / any MCP client | After editing a file, prefetch the likely next one |
CLI neuralmind next <dir> <file> |
Shell, scripts, status lines | Quick lookup or piping into a fzf picker |
Auto-memory SYNAPSE_MEMORY.md |
Claude Code (loads on session start, no user action) | "What typically comes next" section primes the model with the top transitions before any tool call |
Why this matters for agents: the auto-memory section is the single
highest-leverage surface — Claude Code sees SYNAPSE_MEMORY.md on
every session start without anyone asking. An agent priming on
"after src/auth/handlers.py, the human usually opens
tests/test_auth.py" can proactively offer to update the test, rather
than waiting to be asked. Zero user prompts; the prediction is just
in context.
The transition signal needs a long observation window to converge (N files edited together yield only N-1 ordered pairs), so running the watcher as a service via the always-on guide shortens time-to-useful-predictions from weeks to days.
Every learned association now carries a namespace. On main nothing
changes — your memory is the personal namespace, read at full weight. The
moment you git checkout -b feature-x, new activations land in
branch:feature-x, and recall reads a merged view: branch-local context
at 1.0×, long-term personal at 0.8×, an imported shared team baseline at
0.5× (explicit constants — query --trace attributes every boost to the
namespace that drove it). Session scratch goes to ephemeral, which decays
fast and is cleared at the next SessionStart.

Combined effect: 5–10× total reduction vs baseline Claude Code.
You: "How does authentication work in my codebase?"
❌ Traditional: Load entire codebase → 50,000 tokens → $0.15–$3.75/query
✅ NeuralMind: Smart context → 766 tokens → $0.002–$0.06/query
The dollar figures depend on your workload. Run neuralmind benchmark . --contribute to get numbers for your codebase and query volume. Order-of-magnitude expectations:
| You today | NeuralMind likely saves | Setup pays back in |
|---|---|---|
| <$50/mo on LLM, small repo | $5–15/mo | months — probably skip |
| $50–500/mo, 10K+ line repo | $20–200/mo | days |
| $500–5,000/mo team workload | hundreds–thousands/mo | hours |
| Already using prompt caching + long context | smaller marginal win | measure first |
These are directional. The Honest Assessment explains why retrieval-token reduction (40–70×) ≠ end-to-end cost reduction (3–10× typical), and when NeuralMind is and isn't worth installing.
NeuralMind benchmarks itself in CI on every PR. But your codebase isn't our fixture. The only way to know what it does for you is to measure it on your code.
pip install neuralmind # built-in tree-sitter backend — no graphify needed (v0.15.0+)
cd /path/to/your-project
neuralmind build .
neuralmind benchmark .You'll get back your actual reduction ratio and per-query token count — typically 30–80× on real repos. No telemetry, nothing uploaded, nothing committed. If the numbers don't justify it, pip uninstall neuralmind and move on — 5 minutes lost.

Full walkthrough: Does NeuralMind work on your codebase?
Two ways to decide: start with what's annoying you (symptoms), or start with what you're trying to achieve (goals).
| What you notice | Reach for | Why it fixes it |
|---|---|---|
| Agent starts every session not knowing my codebase | neuralmind install-hooks . + neuralmind watch . |
SYNAPSE_MEMORY.md auto-loads on session start with learned associations + transitions |
| I keep telling the agent "after you edit X, also update Y" | neuralmind watch . (v0.11.0+) |
Directional transitions learn the pattern; agent proactively suggests the follow-up |
| Multi-agent setup (Claude Code + Cursor + Cline) — each one has its own context | NeuralMind MCP server | Shared synapse store; learning from one agent benefits the others |
| Claude Code hits context limits mid-task | neuralmind install-hooks . |
Auto-compresses Read/Bash/Grep before the agent sees them (~88–91%) |
| My monthly LLM bill is climbing | neuralmind query + hooks |
40–70× fewer tokens per code question; 5–10× per session combined |
| I start every session re-pasting project structure | neuralmind wakeup . |
~400 tokens of orientation; pipe into any chat |
| Agent reads a 2,000-line file to answer about one function | neuralmind skeleton <file> |
Functions + call graph, no body; ~88% cheaper than Read |
grep floods the agent with hundreds of matches |
neuralmind install-hooks . |
Caps at 25 matches with "N more hidden" pointer |
| The agent is confidently wrong about what my code does | Start session with wakeup; ask with query |
Grounds the model in real structure instead of guessing |
| I want to query my codebase from ChatGPT / Gemini | neuralmind wakeup . | pbcopy |
Model-agnostic output; paste into any chat |
| Retrieval feels random across similar questions | neuralmind learn . |
Cooccurrence-based reranking adapts to your patterns |
| Index feels out of date after a refactor | neuralmind build . (or init-hook once) |
Incremental — only re-embeds changed nodes |
| If your goal is… | Do this | Expected outcome |
|---|---|---|
| Give the agent persistent memory of your codebase | install-hooks + neuralmind watch . |
SYNAPSE_MEMORY.md primes the agent every session — associations + transitions learned from how you actually work |
| Predict the next file the agent should open | install-hooks + neuralmind watch . (v0.11.0+) |
After observing edit patterns, agent surfaces "after X, you usually edit Y (45%)" without being asked |
| Cut LLM spend on code Q&A | install-hooks + use query for questions |
5–10× total reduction (the measurable side effect of better memory) |
| Faster, more grounded agent responses | wakeup at session start → query / skeleton during |
Fewer hallucinations; less re-exploration |
| Keep all code local (no SaaS, no telemetry) | Default install — no extra config | 100% offline; nothing leaves the machine |
| Work across Claude + GPT + Gemini with one index | Build once, pipe output into any model | Same context quality, model-agnostic |
| Make retrieval adapt to how your team queries | Enable memory (TTY prompt) + neuralmind learn . |
Relevance improves on repeat patterns |
| Measure savings for a manager or stakeholder | neuralmind benchmark . --json |
Per-query tokens, reduction ratios, dollar estimate |
| Auto-refresh the index as code changes | neuralmind init-hook . (git post-commit) |
Every commit rebuilds incrementally |
You probably don't need NeuralMind if:
- Your codebase is under ~5K tokens total (just paste the whole thing in).
- You don't use an AI coding agent.
- You only want inline completions — use Copilot or Cursor directly.
You almost certainly want NeuralMind if your AI coding agent feels amnesiac — it doesn't remember what it learned about your code, doesn't predict what you'll need next, doesn't carry context between sessions. The brain layer is what closes that gap. The token-savings are the receipts.
See the use-case walkthroughs for step-by-step guides matched to your situation.
We'd rather you trust the numbers than be wowed by them, so here's the candid take a feature list won't give you.
What genuinely sets it apart
- It measures whether the memory actually helps — and gates it in CI. Most code-RAG tools assert; NeuralMind ships a faithfulness eval (+0.143 vs naive at a matched token budget), an onboarding-lift eval (+6.5 pts), and a synapse-recall A/B (+12 pts), each failing the build on regression. That measurement discipline is the real moat. (Benchmarks)
- Learned usage memory, not just embeddings. The synapse layer learns what your team edits together and what you touch next — and the onboarding-lift metric proves it's not decoration.
- 100% local, and now optionally ChromaDB-free (v0.21.0) with byte-identical embeddings and an 8–16× smaller index.
Where it's still rough — set expectations accordingly
- The headline 40–70× is a real-repo extrapolation. What's measured in CI is a deliberately conservative 6.2× on a 500-line fixture. The mechanism scales with repo size, but a large-repo benchmark isn't in CI yet — so prove it on your code with
benchmark-your-repo. - ChromaDB is still the default. The slim, advisory-free stack is opt-in (
backend: turbovec) while it bakes; the default-flip + dependency removal are staged for later releases. - It's beta, single-maintainer, fast-moving. Lots of surface area (hooks, watcher, serve, MCP, evals) and frequent releases — expect occasional churn; pin a version for CI.
- The compressed backend is approximate. TurboQuant parity is gated on the reference fixture; large-repo recall under 2/4-bit quantization is "trust the gate," not yet measured at scale.
If those trade-offs are acceptable, the upside is real and receipts are included. If your repo is tiny or you don't use an agent, you don't need this — and we'd rather say so.
If you're building a pitch for your team — finance, healthcare, legal, government, internal-platform, or just a large engineering org with a climbing LLM bill — start with docs/BUSINESS-CASE.md for the fact-based ROI argument and docs/ENTERPRISE.md for the regulated/on-premise/multi-team scenarios.
Both docs ground every claim in something you can verify with one command on your own code.

Cursor @codebase |
Works only in Cursor; NeuralMind works in any agent and adds tool-output compression |
| Aider repo-map | Aider is syntactic only; NeuralMind adds semantic retrieval and compression |

NeuralMind installs five ways. The CLI, semantic indexing, and the MCP server (for Claude Code, Cursor, Cline, Continue, and any MCP client) come in every path.
| Method | Command | When to pick |
|---|---|---|
| pip | pip install neuralmind |
Default. Drops it in your active env. |
| pipx | pipx install neuralmind |
Global CLI, no env pollution. Recommended if you want neuralmind available everywhere. |
| uv | uv pip install neuralmind |
Modern, fast Python tooling. ~10× faster install than pip. |
| Docker | docker pull ghcr.io/dfrostar/neuralmind:latest && docker run --rm -v "$PWD:/project:ro" ghcr.io/dfrostar/neuralmind:latest neuralmind --help |
Containerized — no Python on the host. Multi-platform (linux/amd64 + linux/arm64); auto-published to GHCR on every release since v0.9.0. To build locally instead: docker build -t neuralmind:dev . and substitute that tag. |
| From source | git clone … && pip install -e . |
Hacking on NeuralMind itself. |
No external tools required. Since v0.15.0 a built-in tree-sitter backend indexes Python, TypeScript, and Go out of the box — pip install neuralmind && neuralmind build . just works, no graphify install. Optional extras:
pip install graphifyy— use the legacy graphify graph backend instead of the built-in one (held at parity by a CI gate).pip install "neuralmind[turbovec]"— the ChromaDB-free vector backend (v0.21.0+): smaller deps, 8–16× smaller index, same answer quality. See ChromaDB-free local.
Verify install:
neuralmind --help # works for every install path
# For pip / uv / source (a Python env where neuralmind is importable):
python -c "import neuralmind; print(neuralmind.__version__)"The python -c line is skipped for pipx and Docker — pipx isolates the package in its own venv, and Docker doesn't expose the in-container Python.
Walkthrough with pros/cons of each path: docs/use-cases/install-paths.md.
# Install via any path above, then:
# Go to your project

# Build the index — the built-in tree-sitter backend generates the

# Or browse it: Obsidian-style graph view of your codebase + learned synapses
neuralmind serve .neuralmind serve opens a local web UI that makes the same index your AI agent
queries inspectable by a human. Same ChromaDB index, same synapses.db, just
made navigable.
- Force-directed graph of code nodes coloured by community.
- Structural edges (calls / imports) layered with the Hebbian synapse overlay — edges thicken as the brain learns which nodes co-activate.
- Backlinks, outgoing links, and synaptic neighbours for any node you click, Obsidian-style.
- Semantic quick-switcher — type a phrase, jump to the node.
- Open in editor — click a node, opens
$EDITOR(or--editor code/cursor/vim/subl/idea) at the right file and line. - Local-first: stdlib HTTP server, vanilla-JS canvas, no CDN, per-session access token bound to 127.0.0.1 by default.
neuralmind serve . # opens http://127.0.0.1:8765/?token=…
neuralmind serve . --editor "code -n" # override the editor
neuralmind serve . --no-auth # skip the token (trusted hosts only)Why it matters: the agent-facing brain has always been a black box — you couldn't see what NeuralMind retrieved, whether the graph was reasonable, or what the synapse layer had actually learned. The graph view exposes all three.
Coming next (graph-view Phase B): a
replay-last-query overlay
that highlights the L3 hits the agent received,
edge tooltips + a min-weight synapse slider
answering "why are these two nodes related?", pin UX, and a
Cmd/Ctrl-K quick-switch. Then Phase C: a live activity feed of
synapse co-activations. Full plan in ROADMAP.md.
NeuralMind wraps a knowledge graph (graphify-out/graph.json) in a ChromaDB vector store.
Since v0.15.0 that graph is produced by a built-in tree-sitter backend when no graphify
output exists, so neuralmind build . works with no external tool; a real graphify graph still
takes priority where present. When you query it, a 4-layer progressive disclosure system loads
only the context relevant to your question.

}Hermes-Agent is a self-improving agent framework that supports MCP servers. NeuralMind has been verified end-to-end against Hermes-Agent v0.12.0 (build 2026.4.30) — the agent discovered all 11 NeuralMind tools (4-second handshake) when registered as shown below.
Prerequisite: install NeuralMind. The MCP server (neuralmind-mcp)
ships with the default install:
pip install neuralmindOlder
pip install "neuralmind[mcp]"commands still work — themcpextra is preserved as a no-op for backwards compatibility.
Two ways to register the server. Both end up in ~/.hermes/config.yaml:
Option A — CLI (recommended for first-time setup):
hermes mcp addOption B — edit the config directly (~/.hermes/config.yaml, add under
the mcp_servers top-level key):
mcp_servers:
neuralmind:
command: "neuralmind-mcp"
args: ["/absolute/path/to/project"]Verify the server is registered and reachable:
hermes mcp list # neuralmind should appear, status ✓
hermes mcp test neuralmind # ✓ Connected, ✓ Tools discovered: 11If you haven't installed Hermes-Agent yet, the upstream installer is:
curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash
source ~/.bashrcAfter editing the YAML directly, run /reload-mcp from the running hermes
CLI to pick up the change without restarting (the hermes mcp add flow does
this automatically). Both stdio (shown above) and HTTP transports are
supported — see the upstream
MCP integration docs
for the full schema (command, args, env, url, headers, enabled,
per-server tools filtering, timeout, connect_timeout).
v0.6.0 graph view works identically here. Run neuralmind serve in
the same project and any tool call from Hermes-Agent will pulse the
corresponding nodes on the canvas. The synapse store is shared with
Claude Code, Cursor, OpenClaw, and any other agent pointed at this
project — see docs/use-cases/multi-agent.md.
OpenClaw is a personal AI assistant
that registers MCP servers via its CLI. Verified against OpenClaw 2026.5.2 —
mcp set / mcp list / mcp show round-trip the documented JSON schema
into ~/.openclaw/openclaw.json exactly as expected.
Prerequisite: install NeuralMind (the MCP server ships with the default install):
pip install neuralmindRegister NeuralMind:
openclaw mcp set neuralmind '{"command":"neuralmind-mcp","args":["/absolute/path/to/project"]}'Verify it landed:
openclaw mcp list # neuralmind should appear
openclaw mcp show neuralmind # echoes the JSON you storedRemove with openclaw mcp unset neuralmind. Definitions are stored under
the mcp.servers key in ~/.openclaw/openclaw.json.
v0.6.0 graph view works identically here. Run neuralmind serve in
the same project and any tool call from OpenClaw will pulse the
corresponding nodes on the canvas. OpenClaw and Claude Code talking
to the same project reinforce the same synapse store — see
docs/use-cases/multi-agent.md.
If you haven't installed OpenClaw yet:
npm install -g openclaw@latest # or: pnpm add -g openclaw@latest
openclaw onboard --install-daemonOpenClaw's MCP support covers stdio (shown above), SSE, HTTP, and
streamable-http transports — see the upstream
MCP CLI reference for details on
url/transport config and the inverse direction (openclaw mcp serve,
which exposes OpenClaw's own channels as an MCP server to other clients).
Agent Zero is a self-organising AI agent framework with first-class MCP support — both as a client (it consumes MCP servers) and as a server (it exposes its own tools to other MCP clients). NeuralMind plugs in via the standard MCP client path.
Prerequisite: install NeuralMind (the MCP server ships with the default install):
pip install neuralmindRegister NeuralMind via Agent Zero's Web UI:
- Open Agent Zero → Settings → MCP/A2A → External MCP Servers → Open
- Paste this into the JSON editor:
{
"mcpServers": {
"neuralmind": {
"command": "neuralmind-mcp",
"args": ["/absolute/path/to/your-project"]
}
}
}- Click Apply now. Agent Zero discovers NeuralMind's tools at handshake and registers them into the normal tool registry.
The schema is the standard MCP command / args / env shape — see
the upstream MCP setup guide
for HTTP/SSE transports, OAuth, and per-server tool filtering.
If you haven't installed Agent Zero yet, the upstream README has the Docker and Python install paths.
v0.6.0 graph view works identically here. Run neuralmind serve in
the same project and any tool call from Agent Zero will pulse the
corresponding nodes on the canvas. The synapse store is shared with
Claude Code, Cursor, Cline, Continue, OpenClaw, Hermes-Agent, and any
other agent pointed at this project — see
docs/use-cases/multi-agent.md.
Coming soon — one-click install. NeuralMind is being submitted to the
agent0ai/a0-pluginsregistry so users can discover and install it from inside Agent Zero's Plugin Hub. The manual JSON path above continues to work either way.
The MCP server gives an agent the actions. The skill at
skills/neuralmind/SKILL.md gives it the
playbook — when to call neuralmind_query vs. neuralmind_skeleton
vs. neuralmind_search, what the outputs look like, and which env-var
escape hatches exist. It is a portable Anthropic-style SKILL.md
(frontmatter + markdown body) so the same file works in any host that
implements the spec.
OpenClaw. Drop the directory into your ClawHub local skills path, or
ship it as part of an OpenClaw plugin by listing skills/ in
openclaw.plugin.json:
cp -r skills/neuralmind ~/.openclaw/skills/
openclaw skills list # neuralmind should appearThe skill is description-matched on triggers like "how does X work" or "find function Y", so you don't need to load it explicitly.
Agent Zero. Drop the same directory into the Agent Zero skills folder:
cp -r skills/neuralmind /path/to/agent-zero/skills/Agent Zero auto-discovers SKILL.md files by description and tag, then
uses its code_execution_tool to call the MCP tools the skill names in
its allowed_tools frontmatter.
Hermes-Agent. Hermes has a first-class skills system that reads the same SKILL.md spec. Drop the directory into the category-organised tree:
mkdir -p ~/.hermes/skills/code-intelligence
cp -r skills/neuralmind ~/.hermes/skills/code-intelligence/Hermes loads skills on demand based on the frontmatter description, so no further wiring is needed. You can also publish the directory as a Hermes tap (a GitHub repo of skill directories) for one-command install across machines. This layers on top of the MCP integration documented in the Hermes-Agent section above — the MCP server still does the work; the skill teaches Hermes when to call it.
Claude Code, Cursor. These already have richer integrations (lifecycle hooks for Claude Code, MCP wiring for Cursor), so the skill is optional. It still works as a portable "agent operating manual" if you want a single file that travels with the project.
The skill duplicates none of NeuralMind's logic — it points the agent at MCP tools that already exist. Edit it like documentation.
"Connection closed" / "Connection failed" right after register. Almost
always means an old NeuralMind install (≤ 0.4.x) where the MCP server was
gated behind the [mcp] extra. From 0.5.0 onward the MCP SDK is bundled.
Fix:
pip install --upgrade neuralmindThen re-run the host's verify step (hermes mcp test neuralmind or
openclaw mcp list).
neuralmind-mcp: command not found. The package installed but the
console script wasn't put on PATH — usually because pip installed into a
user site-packages dir that isn't on PATH. Add ~/.local/bin to PATH or
reinstall in a venv where the entry point is on PATH.
The host shows neuralmind in mcp list but no tools when you query.
Run neuralmind build /path/to/project first — the index has to exist
before the MCP tools can answer queries. The hooks (SessionStart,
UserPromptSubmit, PreCompact from neuralmind install-hooks) need a
built index too.

(#106), pin UX,
and a Cmd/Ctrl-K quick-switch. Phase C after that: a live activity
feed of synapse co-activations. Full plan in
ROADMAP.md.
NeuralMind now runs as a second brain alongside the LLM: a persistent associative memory that learns continuously from how the agent and the codebase actually interact. See the release notes for the full story.

NeuralMind benchmarks itself on every pull request. A hermetic fixture (tests/fixtures/sample_project/) plus a committed query set (tests/fixtures/benchmark_queries.json) runs through the full retrieval pipeline, and CI fails if aggregate reduction drops below a conservative floor (currently 4× on the small fixture — the fixture is intentionally tiny, real repos consistently hit 40–70× as shown below).
📊 All measured numbers in one place: the Benchmarks & Results page collects token reduction, faithfulness delta, synapse +12 pts, onboarding +6.5 pts, and the v0.21 ChromaDB-free parity — each CI-gated, each with a reproduce command and an honest "what we don't claim."
- Phase 1 — Reduction. Naive baseline (every
.pyfile in the fixture concatenated) vsNeuralMind.query()output, per query. All tokens counted withtiktoken. - Phase 2 — Learning uplift. Same queries run cold, then after seeding memory and running
neuralmind learn. Reports the delta in reduction ratio and top-k retrieval hit rate. On a 500-line fixture the numerical uplift is modest by design — the test proves the mechanism persists, not that it's magic. - Per-model breakdown. GPT-4o and GPT-4/3.5 counts are measured via real tiktoken encodings. Claude uses the Anthropic SDK tokenizer when available, else a clearly-labeled estimate derived from published vocab ratios. Llama is always estimated. No fabricated numbers anywhere.
- Memory persistence.
tests/test_memory_persistence.pyasserts events are logged,neuralmind learnproduces a patterns file, and subsequent queries load it without error.

neuralmind benchmark . --contributeOutput shows your reduction ratio, tokens per query, and estimated monthly savings at Claude 3.5 Sonnet pricing. Full walkthrough: Does NeuralMind work on your codebase?
- Heuristic-only baseline (community-reported): 70–80% top-5 retrieval accuracy
- NeuralMind target on the same query set: exceed that baseline via semantic retrieval + learned cooccurrence reranking
The pytest regression gate (tests/test_benchmark_regression.py) currently enforces ≥50% top-k hit rate on the fixture plus ≥4× reduction (low because the fixture is tiny; real repos measure 10× higher).
Measured on real repos: 40–70× reduction per query (see Benchmarks). For a team running 100 queries/day on Claude Sonnet, that is roughly $450/month → $7/month. Exact savings depend on codebase size and model pricing.
Yes. The CLI works anywhere Python runs; the MCP server works with Cursor, Cline, Continue, Claude Desktop, and any MCP-compatible agent. For non-MCP tools like ChatGPT or Gemini, neuralmind wakeup . | pbcopy pipes context into a regular chat window. Only the PostToolUse compression hooks are Claude-Code-specific.
No. NeuralMind is fully offline — no API calls, no cloud services. Embeddings run locally via ChromaDB, and the knowledge graph is stored in graphify-out/ in your project. Query memory (optional, opt-in) is written to .neuralmind/ on disk.
It is a form of RAG, but specialized for code. Instead of chunking text, NeuralMind retrieves over a knowledge graph of code entities (functions, classes, clusters) with a fixed 4-layer structure. That keeps the call graph intact and produces a token-budgeted output instead of a flat list of chunks. See vs. LangChain/LlamaIndex.
Long context makes it possible to stuff a whole repo in; it does not make it cheap. You still pay per input token, so a 50K-token repo at Claude Sonnet rates costs ~$0.15 every turn. NeuralMind drops that to ~$0.002. See vs. long context.
The built-in tree-sitter backend indexes Python, TypeScript, and Go out of the box (v0.16.0+) — a mixed-language repo is indexed in one pass. More grammars slot in behind the same SUPPORTED_SUFFIXES seam. For languages beyond those, install graphify — any language it supports works, since NeuralMind consumes graphify-out/graph.json and graphify takes priority where present. Either producer feeds the same retrieval pipeline.
wakeup— ~400 tokens of project orientation (L0 + L1). Run it at session start.query— ~800–1,100 tokens for a specific natural-language question (L0–L3).skeleton— compact view of a single file (functions + call graph + cross-file edges). Use beforeRead.
When neuralmind install-hooks . has been run, Claude Code invokes NeuralMind after every Read/Bash/Grep tool call but before the agent sees the output. Read becomes a skeleton (~88% smaller), Bash keeps errors + last 3 lines (~91% smaller), Grep caps at 25 matches. Set NEURALMIND_BYPASS=1 on any command to opt out.
The knowledge graph (graphify-out/graph.json) is the source of truth — but as of v0.15.0 you no longer need a separate tool to produce it. neuralmind build . generates it automatically with the bundled tree-sitter backend. Installing graphify is optional and takes priority where present.
Only if you install the git post-commit hook with neuralmind init-hook .. Otherwise run neuralmind build . manually; it is incremental and only re-embeds changed nodes.
- Check that
neuralmind stats .reports all your nodes indexed. - Run
neuralmind benchmark .to see reduction ratios. - Enable query memory (it prompts on first TTY run) and periodically run
neuralmind learn .— cooccurrence-based reranking improves relevance on your actual queries. - Open an issue with the query and expected result — retrieval quality is the thing we most want to improve.

| Release Notes v0.24.0 | Memory namespaces & branch isolation (PRD 4) — every synapse/transition/activation carries a namespace (personal / shared / branch:<name> / ephemeral); lossless single-transaction v0→v1 schema migration (existing memory → personal); transparent merged reads (branch 1.0× > personal 0.8× > shared 0.5×, published constants, per-namespace --trace attribution); new neuralmind memory {inspect,reset,export,import} with versioned JSON bundles (PRD 8 on-ramp); per-namespace decay/TTL (shared sticky, ephemeral fast + cleared at session boundaries); branch auto-detection via stdlib git with safe personal fallback |
| Release Notes v0.23.0 | Versioned index contract (IR) + retrieval-quality harness + debug traces + local daemon. PRD 1: builds materialize a canonical, schema-versioned IndexIR and validate it; new backend-free neuralmind validate; round-trip-faithful graphify⇄IR adapter; learned synapses folded in; IR metadata in build/stats. PRD 2: new neuralmind benchmark --quality measures precision@k / recall@k / MRR / answerability over 30 golden queries (Python/TS/Go), gated in CI. PRD 3: neuralmind query --trace attaches a per-layer retrieval trace (candidates, cluster scoring with vector-vs-synapse attribution, final hits, token budget); bounded + redactable; zero-overhead off by default. PRD 5: experimental neuralmind daemon keeps project state warm (project registry + per-project locks + background jobs + shared dispatch() API); CLI auto-prefers it with direct-mode fallback. Retrieval and existing indexes unchanged |
| Release Notes v0.22.0 | turbovec becomes the default (when available) — import neuralmind no longer needs ChromaDB; default backend is now auto (turbovec when its deps are installed, else chroma); one-time auto-reindex with the old ChromaDB index kept as a fallback; neuralmind doctor shows the resolved backend; staged middle step toward retiring ChromaDB |
| Release Notes v0.21.0 | ChromaDB-free retrieval — opt-in turbovec backend now embeds and searches with zero ChromaDB: TurboQuant compressed index (8–16× smaller vectors) + a bundled OnnxMiniLMEmbedder producing vectors byte-identical to ChromaDB's; at/above parity (fact-recall 0.744→0.800); enable via backend: turbovec; retires the CVE-2026-45829 dependency (default-flip staged for v0.22) |
| Release Notes v0.20.0 | Onboarding-lift eval — neuralmind eval --onboarding measures the learned-synapse uplift (committed team memory vs a cold agent) as a cold/onboarded A/B over the gold queries; headline = top-k module hit-rate lift (fact-recall + grounding as secondaries); CI-gated at lift ≥ 0; evals/onboarding/ mirrors the faithfulness eval |
| Release Notes v0.19.0 | One-command MCP setup — neuralmind install-mcp --all auto-detects Claude Code / Cursor / Cline / Claude Desktop and registers the MCP server with each (non-destructive merge, idempotent); pure-stdlib mcp_install module |
| Release Notes v0.18.0 | Incremental per-file graph updates — graphgen.update_files() / NeuralMind.update_files() re-parse only changed files (unchanged files stay byte-identical so the embedder skips them), wired to the watcher via neuralmind watch --reindex |
| Release Notes v0.17.0 | Optional SCIP precision pass — NEURALMIND_PRECISION=1 folds compiler-accurate calls/inherits edges from a *.scip index into the built-in graph (replacing heuristic ones for covered files); off by default, dependency-free stdlib SCIP reader, proven by a precision check in the CI gate |
| Release Notes v0.16.0 | Multi-language built-in backend — TypeScript + Go extractors behind the SUPPORTED_SUFFIXES seam, neuralmind build indexes Python/TS/Go with no graphify; proven at parity per language by the CI gate (100% symbol coverage on the reference fixtures) |
| Release Notes v0.15.0 | Built-in tree-sitter graph backend — neuralmind build works with no graphify install; graphify still takes priority where present; backend swap proven at parity by a new CI gate (reduction + faithfulness within tolerance) |
| Release Notes v0.14.0 | neuralmind eval — measure answer faithfulness (expected-fact recall vs a matched-budget naive baseline) with grounding + contradiction checks and --json; 100% local by default |
| Release Notes v0.13.0 | Measurement foundation — offline faithfulness eval (query + gold-fact dataset, expected-fact-recall scorer), polyglot retrieval fixtures (TypeScript + Go), and a standard documentation process |
| Release Notes v0.12.0 | Install Doctor — neuralmind doctor health checks (graph, index, synapses, MCP, hooks, memory), --json output, friendlier "graph not built" error |
| Release Notes v0.11.0 | Directional Synapses — synapse_transitions table, next_likely() API, neuralmind next CLI, neuralmind_next_likely MCP tool |
