unraid-rmcp

unraid-rmcp is a Rust MCP server and CLI for querying an Unraid NAS through the Unraid GraphQL API.

It exposes one MCP tool, unraid, plus the runraid CLI. Agents can inspect array health, disks, Docker containers and logs, VMs, shares, notifications, system metrics, UPS, logs, network settings, plugins, parity history, rclone, remote access, and Unraid Connect through stdio MCP, Streamable HTTP MCP, or direct shell commands.

30-second path: set UNRAID_API_URL and UNRAID_API_KEY, then run npx -y unraid-rmcp server --json -> start loopback HTTP with UNRAID_RMCP_HOST=127.0.0.1 npx -y unraid-rmcp serve mcp -> call tools/call with {"action":"server"}.

Status: operational RMCP upstream-client server. Read-only action surface; no Unraid mutations are exposed. HTTP MCP supports loopback dev mode, static bearer tokens, and Google OAuth through lab-auth. Release binaries and Docker images target linux/amd64 only.

Not for: replacing the Unraid web UI, mutating array/docker/VM state, running arbitrary shell commands, storing API keys for callers, multi-tenant isolation, or passing Unraid API keys through MCP tool arguments.

Naming

Surface	This repo
Repository	unraid-rmcp
Rust crate	unraid-rmcp
Binary / CLI	runraid
npm package	unraid-rmcp
npm binary aliases	unraid-rmcp, runraid
MCP tool	unraid
Config home	~/.unraid on hosts, /data in containers
Env prefixes	UNRAID_*, UNRAID_RMCP_*

This repo is a small naming exception in the RMCP family: MCP/server variables use UNRAID_RMCP_* rather than UNRAID_MCP_* for compatibility with the existing deployment config.

Capabilities And Boundaries

• Read Unraid array state, parity status, disk health, SMART summaries, and capacity.
• Read Docker containers, container logs, VMs, shares, notifications, services, network URLs, live metrics, config vars, registration, flash device details, UPS, plugins, parity history, rclone, remote access, and Unraid Connect.
• Provide pagination/filtering for MCP list actions and output truncation for large MCP responses.
• Expose the server_summary prompt and unraid://schema/mcp-tool schema resource.
• Provide setup and doctor commands for local plugin/runtime checks.

This repo owns	Unraid owns	Explicitly out of scope
MCP/CLI projection, GraphQL query selection, response shaping, pagination, auth policy, setup checks, prompt/resource metadata, and read-only safety.

npm / npx

Run the stdio MCP server or CLI without a manual binary install:

npx -y unraid-rmcp --help
npx -y unraid-rmcp mcp
npx -y unraid-rmcp server --json

The npm package downloads runraid during postinstall. Override download behavior only when testing packaging:

Variable	Purpose
UNRAID_RMCP_SKIP_DOWNLOAD=1	Skip postinstall binary download.
UNRAID_RMCP_VERSION or UNRAID_RMCP_BINARY_VERSION	Select the GitHub Release tag.
UNRAID_RMCP_REPO	Select the GitHub repo used for release downloads.
UNRAID_RMCP_RELEASE_BASE_URL	Select a custom release base URL.

Build From Source

git clone https://github.com/jmagar/unraid-rmcp
cd unraid-rmcp
cargo build --release
./target/release/runraid --help

Minimum supported Rust version: 1.90.

Quickstart

1. Configure Unraid

Create an Unraid API key in Settings -> API Management, then set:

export UNRAID_API_URL="https://10-1-0-2.<hash>.myunraid.net:31337/graphql"
export UNRAID_API_KEY="your-api-key-here"

Set UNRAID_API_SKIP_TLS_VERIFY=true only when your Unraid GraphQL endpoint uses a certificate your host does not trust.

2. Run A Safe CLI Call

npx -y unraid-rmcp server --json

3. Start Loopback HTTP MCP

UNRAID_RMCP_HOST=127.0.0.1 npx -y unraid-rmcp serve mcp

In another shell:

curl -sf http://127.0.0.1:40010/health

4. Make A First MCP Call

curl -s -X POST http://127.0.0.1:40010/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"unraid","arguments":{"action":"server"}}}'

  }
}

Codex / Labby Gateway

Register Unraid through Labby as an HTTP upstream when sharing one long-running server, or run it directly as stdio for local-only use.

[mcp_servers.unraid]
command = "npx"
args = ["-y", "unraid-rmcp", "mcp"]

Generic MCP JSON

{
  "command": "runraid",
  "args": ["mcp"],
  "env": {
    "UNRAID_API_URL": "https://10-1-0-2.<hash>.myunraid.net:31337/graphql",
    "UNRAID_API_KEY": "your-api-key-here"
  }
}

Do not put UNRAID_API_KEY, OAuth secrets, passwords, SSH keys, or upstream bearer tokens in MCP tool arguments. Use env, config files, or the MCP client's secret storage. MCP callers never provide credentials, tokens, keys, or secrets as action arguments.

Host installs read ~/.unraid/.env before loading config. Containers read /data/.env. Process environment overrides both.

Variable	Default	Purpose
UNRAID_API_URL	unset	Full Unraid GraphQL endpoint URL.
UNRAID_API_KEY	unset	API key for the x-api-key header.
UNRAID_API_SKIP_TLS_VERIFY	false	Skip TLS certificate verification for self-signed endpoints.
UNRAID_RMCP_HOST	0.0.0.0	HTTP bind host.
UNRAID_RMCP_PORT	40010	HTTP bind port.
UNRAID_RMCP_SERVER_NAME	unraid-rmcp	Advertised MCP server name.

UNRAID_RMCP_AUTH_MODE	bearer	bearer or oauth.
UNRAID_RMCP_GOOGLE_CLIENT_ID	unset	Google OAuth client ID.
UNRAID_RMCP_GOOGLE_CLIENT_SECRET	unset	Google OAuth client secret.
UNRAID_RMCP_AUTH_ADMIN_EMAIL	unset	Admin email for OAuth bootstrap.

Authentication

Stdio MCP runs as a local trusted child process and does not use HTTP auth.

HTTP MCP auth policy:

State	Condition	Behavior
Loopback dev	UNRAID_RMCP_HOST starts with 127. or auth is explicitly disabled on loopback	Local unauthenticated development is allowed.
Mounted bearer	Non-loopback with UNRAID_RMCP_TOKEN	Requires Authorization: Bearer <token> and action scopes.
Mounted OAuth	UNRAID_RMCP_AUTH_MODE=oauth	Uses Google OAuth/JWT through lab-auth.
Trusted gateway	UNRAID_NOAUTH=true	Assumes a reverse proxy or gateway already enforced auth.

All data actions are read-only. OAuth exposes unraid:read and unraid:admin scopes, but no mutating Unraid action is currently registered.

Safety And Trust Model

• Unraid API keys are loaded from config/env only.
• MCP callers select read actions and filters, not upstream credentials.
• No mutation, shell execution, filesystem write, Docker control, VM control, or array-control action is exposed.
• log_file reads through the Unraid GraphQL API, not arbitrary local files.
• Non-loopback HTTP deployments must use bearer auth, OAuth, or a trusted authenticated gateway.
• This bridge does not sandbox Unraid itself. Unraid remains responsible for API permissions and GraphQL response semantics.

Architecture

GraphQL queries (src/graphql.rs)  typed/read-only query construction
        |
UnraidService (src/app.rs)       action behavior and response shaping
        |
MCP shim      (src/mcp/tools.rs) JSON args -> service -> Value
CLI shim      (src/cli.rs)       argv -> service -> stdout

Distribution Contract

• Cargo.toml, Cargo.lock, packages/unraid-rmcp/package.json, .release-please-manifest.json, and server.json must agree on the released version.
• GitHub Releases publish the linux/amd64 runraid binary consumed by the npm launcher.
• The npm package name is unraid-rmcp; binary aliases are unraid-rmcp and runraid.
• Docker/OCI metadata uses ghcr.io/jmagar/unraid-rmcp:<version>.
• plugins/unraid/.mcp.json must launch npx -y unraid-rmcp mcp so stdio clients start the MCP transport rather than the HTTP server.
• The root README is curated. docs/INVENTORY.md is the curated inventory for actions, CLI commands, env vars, HTTP endpoints, and dependencies.

Development

cargo fmt --check
cargo test
cargo clippy -- -D warnings
cargo build --release
npm --prefix packages/unraid-rmcp run check

Verification

python3 /home/jmagar/workspace/soma/scripts/check-readme-guide.py README.md
npm --prefix packages/unraid-rmcp run check
cargo check
cargo test
git diff --check

Runtime smoke:

UNRAID_API_URL=https://10-1-0-2.<hash>.myunraid.net:31337/graphql \
UNRAID_API_KEY=... \
runraid server --json

HTTP smoke:

UNRAID_RMCP_HOST=127.0.0.1 runraid serve mcp
curl -sf http://127.0.0.1:40010/health

Deployment

Use loopback for local development:

UNRAID_RMCP_HOST=127.0.0.1 runraid serve mcp

Use Docker Compose for shared HTTP deployment:

cp .env.example .env
docker compose up -d

When binding to a non-loopback address, configure UNRAID_RMCP_TOKEN, UNRAID_RMCP_AUTH_MODE=oauth, or UNRAID_NOAUTH=true behind an authenticated gateway.

Troubleshooting

Symptom	Check
UNRAID_API_URL or UNRAID_API_KEY is missing	Set it in env or ~/.unraid/.env.
TLS errors against Unraid	Set UNRAID_API_SKIP_TLS_VERIFY=true only for self-signed endpoints.
HTTP /mcp returns unauthorized	Set UNRAID_RMCP_TOKEN and send Authorization: Bearer <token>.
Stdio client hangs or logs JSON errors	Ensure client config runs unraid-rmcp mcp, not the default HTTP server mode.
Large list response is truncated	Use limit, offset, name, or state filters on MCP list actions.
docker_logs fails	Pass a valid container id and optional tail.
