| name | codegraph-tool |
| description | CodeGraph — Pre-indexed code knowledge graph tool. Provides semantic code intelligence for Claude Code, Cursor, Codex, Gemini, OpenCode, Hermes, Antigravity, Kiro and other AI agents. |
CodeGraph Tool
Local-first code intelligence tool. tree-sitter parsing → SQLite (FTS5) storage → MCP exposes knowledge graph.
Use Cases
Use when users need to install CodeGraph, initialize code graph, index projects, understand code structure, trace call chains, evaluate change impact.
Installation
npx @colbymchenry/codegraph
curl -fsSL https://raw.githubusercontent.com/colbymchenry/codegraph/main/install.sh | sh
npm i -g @colbymchenry/codegraph
Non-interactive: codegraph install --yes [--target=claude,cursor] [--location=local]
Project Initialization
cd your-project
codegraph init -i
codegraph index
codegraph sync
codegraph status
MCP Tools (8)
Tool selection guide is automatically sent to Agent in MCP initialize response.
| Intent | Tool | Key Parameters |
|---|
| Almost any question — architecture, flow, bug, investigation | codegraph_explore ⭐ | query (natural language or symbol names) |
| Locate symbol by name | codegraph_search | query, kind, limit |
| Call chain | codegraph_callers / codegraph_callees | symbol, limit |
| Change impact | codegraph_impact | symbol, depth |
| Single symbol full source / overload disambiguation | codegraph_node | symbol, includeCode, file, line |
| File structure | codegraph_files | — |
| Index health | codegraph_status | — |
Core Principles
codegraph_explore is the PRIMARY tool — call it first, usually the only call needed. Returns relevant symbol source code (grouped by file), with line numbers.- Answer directly, don't delegate to sub-Agent for file exploration — CodeGraph IS the pre-built index, grep/read loops are redundant work.
- One
explore > search + node chained calls.
Anti-patterns
❌ Don't use grep to verify codegraph results (AST is more accurate than grep)
❌ Don't chain search + node to understand an area (one explore does it)
❌ Don't loop node over multiple symbols (one explore returns all)
⚠️ Check staleness banner after edits — pending files need direct Read
Auto-sync
Three-layer protection: ① Native FS events + 2s debounce auto-sync ② Per-file staleness banner (pending files prefixed with ⚠️) ③ Auto-reconciliation on MCP reconnect.
Manual sync only needed in sandbox (CODEGRAPH_NO_DAEMON=1) or CI pre-flight.

Configuration
Zero-config — no config files. Auto-excludes node_modules/vendor/dist/build/target/.venv/Pods/.next + .gitignore entries + >1MB files. Exclude more: add to .gitignore; bring back: !vendor/.
