v0.3.5

XcodeMCPKit v0.3.5

Improvements

• Stabilize tools/list handshakes by warming once (fail-fast) and serving an in-memory cached result for the lifetime of the proxy process (including requests with params).
• Improve multi-upstream warmup behavior by tracking warmup failures and temporarily quarantining upstreams that fail warmup.

Bug Fixes

• Drop unmapped upstream JSON-RPC responses so late tools/list warmup replies can’t leak into active sessions.
• Make upstream process restarts race-safe and suppress exit events for superseded processes.
• Harden STDIO framing to avoid stalls on Content-Length-looking log lines and to recover from bogus Content-Length blocks.

Documentation

• Clarify the fail-fast tools/list warmup timeout in troubleshooting docs.

Full Changelog: v0.3.4...v0.3.5

v0.3.4

XcodeMCPKit v0.3.4

Bug Fixes

• Reduce cross-talk between concurrent sessions by pinning each MCP session to a specific upstream mcpbridge process, and route unmapped server messages only to sessions pinned to the same upstream.

Full Changelog: v0.3.3...v0.3.4

v0.3.3

XcodeMCPKit v0.3.3

Bug Fixes

• Return empty results for resources/list and resources/templates/list before the proxy is initialized (some clients probe these unconditionally).
• After initialization, forward resources listing when supported and only rewrite JSON-RPC "Method not found" (-32601) to an empty list (other upstream errors pass through unchanged).

Full Changelog: v0.3.2...v0.3.3

v0.3.2

XcodeMCPKit v0.3.2

Improvements

• Prefer JSON over SSE for POST calls when the client accepts both (application/json + text/event-stream).
• Make xcode-mcp-proxy-server the dedicated HTTP/SSE proxy server (default listen: localhost:8765) and xcode-mcp-proxy the dedicated STDIO adapter for Codex / Claude Code.
• Add --force-restart to xcode-mcp-proxy-server to terminate an existing server when the listen port is already in use.
• Add --url as a more intuitive alias for pointing the STDIO adapter at a running proxy server (discovery / XCODE_MCP_PROXY_ENDPOINT still supported).

Bug Fixes

• Fix a hang after upstream disconnects (Transport closed).
• Fix tools/list caching + warmup so cached results are only served for canonical no-params requests and warmup won’t collide with real sessions.
• Improve proxy server PID detection by using the full process command line (avoids truncated ps output).

Documentation

• Update README and troubleshooting for the new Codex / Claude setup, discovery file location, --force-restart, and Transport closed guidance.

Full Changelog: v0.3.1...v0.3.2

v0.3.1

XcodeMCPKit v0.3.1

Documentation

• Simplify MCP registration by showing how to replace xcrun mcpbridge with xcode-mcp-proxy for Codex and Claude Code.
• Streamline troubleshooting for upstream xcrun mcpbridge execution (Xcode selection and xcrun mcpbridge -h checks).

Full Changelog: v0.3.0...v0.3.1

v0.3.0

XcodeMCPKit v0.3.0

New Features

• Add --upstream-processes (1..10) to spawn a pool of upstream xcrun mcpbridge processes, improving throughput under higher client concurrency.

Bug Fixes

• Make eager initialization more resilient by retrying after warm init failures and after the last upstream process exits.

Documentation

• Expand the architecture docs to describe upstream pooling and STDIO adapter mode.
• Add benchmark notes, results, and a benchmark tool (Tools/mcp_bench.swift) comparing --upstream-processes 1 vs 4, with guidance on when multiplexing helps.

Full Changelog: v0.2.1...v0.3.0

v0.2.1

XcodeMCPKit v0.2.1

New Features

• Default HTTP proxy listen address to localhost:0 (auto-assign port) and write the resolved endpoint to ~/Library/Caches/XcodeMCPProxy/endpoint.json for HTTP/SSE client discovery.
• When --stdio is used without an explicit URL, resolve the upstream in order: XCODE_MCP_PROXY_ENDPOINT, discovery file, then http://localhost:8765/mcp.

Improvements

• Log whether the STDIO upstream came from CLI, env, discovery, or fallback to make connectivity issues easier to diagnose.

Documentation

• Document endpoint discovery and STDIO upstream resolution in the README and architecture docs.
• Add troubleshooting guidance for clients when the proxy runs on an auto-assigned port.
• Add a detailed investigation note (with diagrams) for the Xcode MCP connection permission dialog in Xcode 26.3.

Full Changelog: v0.2.0...v0.2.1

v0.2.0

XcodeMCPKit v0.2.0

New Features

• Add xcode-mcp-proxy-server (HTTP/SSE) plus xcode-mcp-proxy --stdio adapter so STDIO-only clients can connect through a central proxy.
• Add xcode-mcp-proxy-install to install xcode-mcp-proxy and xcode-mcp-proxy-server to ~/.local/bin (supports --prefix / --bindir).

Bug Fixes

• Bind localhost on both IPv4 and IPv6 loopback (with IPv6-only fallback) to avoid connection failures on IPv6-only setups.
• Fix STDIO mode timeouts: honor --request-timeout 0 and preserve POST timeouts while keeping SSE long-lived.

Improvements

• Default listen host/upstream to localhost (HTTP and STDIO).
• Automatically reinitialize after upstream mcpbridge exits to keep the proxy available.

Documentation

• Add architecture overview with HTTP/SSE and STDIO adapter diagrams.
• Add troubleshooting guide, including Codex timeout guidance.

Full Changelog: v0.1.3...v0.2.0

v0.1.3

XcodeMCPKit v0.1.3

New Features

• Allow disabling request timeouts by setting --request-timeout 0 (no scheduled timeout for requests/batches/init).

Improvements

• Increase the default request timeout to 300 seconds to reduce premature timeouts.

Documentation

• Add an investigation note on the Xcode 26.3 MCP connection permission dialog and known-agent behavior.

Tests

• Add coverage for disabled request timeout behavior in ProxyRouter.

Full Changelog: v0.1.2...v0.1.3

v0.1.2

XcodeMCPKit v0.1.2

New Features

• Add ProxyLogging with opt-in ProxyLogging.bootstrap() and env-based log level (MCP_LOG_LEVEL/LOG_LEVEL).

Improvements

• ProxyLogging.make no longer auto-bootstraps swift-log; call ProxyLogging.bootstrap() when you want logging configured.
• Refactor upstream handling and session protocol flow for better testability.

Other Changes

• Expand test coverage for HTTP handling, session management, CLI/logging, and concurrency; enable the concurrency stress test by default.
• Update README with logging environment variables.
