 36c8dbc404 fix(mcp): don't block initialize handshake on heavy init (#172) (#177) 
The MCP `initialize` handler was awaiting `tryInitializeDefault` —
which opens the SQLite DB and runs `await initGrammars()` (tree-sitter
WASM bootstrap) — before sending the JSON-RPC response. On slow
filesystems (Docker Desktop VirtioFS on macOS, WSL2) this could exceed
Claude Code's ~30s handshake timeout, leaving the codegraph child
process alive and unresponsive with no tools visible in the client.

Send the response first; defer the open to a tracked background
promise. The lazy retry path used by `tools/list` and `tools/call`
now awaits that promise instead of racing it with `openSync`, so we
never double-open the SQLite file.

Adds a subprocess-based regression test that asserts the JSON-RPC
response arrives on stdout before `startWatching()` logs to stderr.
This ordering check catches the regression on any filesystem, not
just slow ones where the timing matters in practice.

Reported by @sashanclrp; isolated by @sgrimm's wire capture.

Changelog

All notable changes to CodeGraph are documented here. Each entry also ships as a GitHub Release tagged vX.Y.Z, which is where most people will look.

This project follows Keep a Changelog and adheres to Semantic Versioning.

0.7.10 - 2026-05-19

Fixed

  • MCP: tools no longer silently fail to appear in clients on slow filesystems (Docker Desktop VirtioFS on macOS, WSL2). The initialize handshake was blocking on opening the SQLite database and bootstrapping the tree-sitter WASM runtime, which on slow I/O could exceed Claude Code's ~30s handshake timeout — leaving the codegraph process alive but unresponsive and no tools visible. The handshake now returns immediately and defers project open to the background; tool calls wait on the in-flight init rather than racing it with a second open. Closes #172. Thanks to @sashanclrp for the original report and detailed reproduction, and @sgrimm for the decisive wire capture that isolated the actual root cause.

0.7.8 - 2026-05-17

Fixed

  • opencode: install actually wires up the MCP server now. v0.7.7 wrote ~/.config/opencode/opencode.json, but opencode reads opencode.jsonc by default — so the codegraph entry never showed up in any opencode session. The installer now prefers an existing .jsonc, falls back to .json when only that exists, and creates .jsonc for greenfield installs. Re-run codegraph install --target=opencode after upgrading so the entry lands in the file opencode actually reads.

Added

  • opencode: installer now writes AGENTS.md (global ~/.config/opencode/AGENTS.md, local ./AGENTS.md) with the same codegraph usage guidance the other agents already received. Without it, opencode's model would call native Grep instead of the codegraph_* tools it could see in its MCP list.
  • User comments and formatting in opencode.jsonc survive install / re-install / uninstall round-trips — surgical edits via jsonc-parser rather than full-file rewrites.

0.7.7 - 2026-05-17

Added

  • Multi-agent installer (closes #137). codegraph install now opens with a multi-select prompt for Claude Code, Cursor, Codex CLI, and opencode — detected agents are pre-checked. Each writes its native MCP config + instructions file (e.g. ~/.cursor/mcp.json
    • .cursor/rules/codegraph.mdc, ~/.codex/config.toml + ~/.codex/AGENTS.md, ~/.config/opencode/opencode.json). The runtime MCP server was already agent-agnostic; this brings the installer to parity.
  • Non-interactive install flags for scripting / CI: --target=<csv|auto|all|none>, --location=<global|local>, --yes, --no-permissions, --print-config <id>.
  • codegraph init now auto-wires project-local agent surfaces for any agent configured globally. In practice: Cursor's .cursor/rules/codegraph.mdc is dropped on init so a single global codegraph install works in every project you open — no per-project re-install needed.

Fixed

  • Cursor: globally-installed codegraph reported "not initialized" in every workspace because Cursor launches MCP-server subprocesses with the wrong working directory and doesn't pass rootUri in the MCP initialize call. We now inject --path into Cursor's MCP args — absolute path for local installs, ${workspaceFolder} for global installs.

Changed

  • Agent-instructions template is now agent-agnostic. The previous template was inherited from the Claude-only era and prescribed "spawn an Explore agent" — a Claude Code-specific concept that confused Cursor's and Codex's agents and caused them to fall back to native grep even with codegraph available. The new template adds explicit "trust codegraph results, don't re-verify with grep" guidance and a clear tool-by-question matrix. Applies to ~/.claude/CLAUDE.md, .cursor/rules/codegraph.mdc, and ~/.codex/AGENTS.md.
  • codegraph install prompt order: agent picker is now step 1, before the PATH-install and location prompts.
  • Disambiguated "global" wording in install prompts ("Install codegraph CLI on your PATH?" vs "Apply agent configs to all your projects, or just this one?") — both used to say "Global" and read as duplicates.

Internal

  • New AgentTarget interface in src/installer/targets/ — adding a 5th agent (Continue, Zed, Windsurf, …) is a new file + one entry in registry.ts.
  • Hand-rolled TOML serializer for Codex (src/installer/targets/toml.ts) — no new dependency, scoped to the [mcp_servers.codegraph] table only, sibling tables and [[array_of_tables]] preserved verbatim.
  • +47 parameterized contract tests across the 4 targets — install idempotency, sibling preservation, uninstall reverses install, byte-equal re-runs return unchanged, partial-state recovery for Codex.

Based on substantive draft by @andreinknv (fork commit c5165e4). Thank you.

0.7.6 - 2026-05-13

Fixed

  • codegraph CLI failing with zsh: permission denied: codegraph after a fresh global install. The published 0.7.5 tarball shipped dist/bin/codegraph.js without the executable bit, so the shell refused to run it through the npm symlink. The build now chmod +x's the binary before packing.

    Already on 0.7.5? Either upgrade to 0.7.6, or unblock yourself in place:

    chmod +x "$(npm root -g)/@colbymchenry/codegraph/dist/bin/codegraph.js"
