CodeGraph

CodeGraph is a pre-indexed code knowledge graph + MCP server. It parses your codebase with tree-sitter (backed by a native Rust kernel), stores every symbol, edge, and file in SQLite (FTS5), and exposes it to AI agents through MCP tools. Auto-syncs on file changes.

Repo: https://github.com/colbymchenry/codegraph Version: 1.5.0+

Quick Start

1. Install CodeGraph CLI

# Via npm (any platform)
npm i -g @colbymchenry/codegraph

# Or via installer (no Node.js required):
#   macOS/Linux: curl -fsSL https://raw.githubusercontent.com/colbymchenry/codegraph/main/install.sh | sh
#   Windows: irm https://raw.githubusercontent.com/colbymchenry/codegraph/main/install.ps1 | iex

2. Wire up your agent

codegraph install

Auto-detects and configures: Claude Code, Cursor, Codex CLI, OpenCode, Hermes Agent, Gemini CLI, Antigravity IDE, Kiro.

3. Initialize a project

cd your-project
codegraph init

Creates .codegraph/ directory and builds the full knowledge graph.

MCP Tools

CodeGraph exposes the following MCP tools when running as codegraph serve --mcp:

`codegraph_explore` (PRIMARY — call first)

Answer almost any question in one call: "how does X work", a flow ("how does X reach Y"), or surveying an area.

Input: {
  query: string          // Symbol names, file names, or natural language
  projectPath?: string   // Path to indexed project (default: cwd)
  maxFiles?: number      // Max files to include
}
Output: Symbols' verbatim source grouped by file + call paths + blast radius

`codegraph_node`

Two modes:

Read a file — pass file (path or basename) without symbol → returns line-numbered source (Read-equivalent)

One symbol — returns location, signature, source, caller/callee trail

Input: {
symbol?: string        // Symbol name (qualified or short)
file?: string          // File path or basename
line?: number          // Line number (disambiguation)
includeCode?: boolean  // Include source code (default: true)
projectPath?: string
}

`codegraph_search`

Quick symbol search by name. Returns locations only (no code).

Input: {
  query: string          // Symbol name to search
  kind?: string          // Filter by node kind (class, function, etc.)
  limit?: number         // Max results
  projectPath?: string
}

`codegraph_callers` / `codegraph_callees`

Find what calls a function / what a function calls.

Input: {
  symbol: string         // Symbol name
  limit?: number
  projectPath?: string
}

`codegraph_impact`

List symbols affected by changing a symbol.

Input: {
  symbol: string         // Symbol to analyze
  depth?: number         // Traversal depth (default: 2)
  projectPath?: string
}

`codegraph_files`

Show file structure of the indexed project.

Input: {
  format?: "tree" | "list"
  filter?: string        // Glob pattern
  maxDepth?: number
  projectPath?: string
}

`codegraph_status`

Check if a project is indexed and see its statistics.

Input: {
  projectPath?: string   // If omitted, checks the current project
}

CLI Commands

codegraph                         # Interactive installer
codegraph install                 # Wire up agents
codegraph uninstall               # Remove CodeGraph from agents + CLI
codegraph init [path]             # Initialize + build graph
codegraph uninit [path]           # Remove CodeGraph from project
codegraph index [path]            # Full re-index
codegraph sync [path]             # Incremental sync
codegraph status [path]           # Show index statistics
codegraph unlock [path]           # Remove stale lock file
codegraph query <search>          # Search symbols
codegraph explore <query>         # CLI equivalent of codegraph_explore
codegraph node <symbol|file>      # CLI equivalent of codegraph_node

codegraph version                 # Print version
codegraph help [command]          # Show help

`codegraph affected`

Trace import dependencies to find which test files are affected by changes:

codegraph affected src/utils.ts src/api.ts
git diff --name-only | codegraph affected --stdin
codegraph affected src/auth.ts --filter "e2e/*"

Configuration

Zero-config by default. Optional codegraph.json at project root:

{
  "exclude": ["static/", "**/vendor/**"],
  "include": ["Tools/", "Local/typescript/"],
  "extensions": {
    ".dota_lua": "lua",
    ".tpl": "php"
  }
}

Environment Variables

Variable	Purpose
`CODEGRAPH_WATCH_DEBOUNCE_MS`	File watcher debounce (clamped 100ms–60s, default 2000ms)
`CODEGRAPH_MCP_TOOLS`	Re-enable hidden tools: `explore,node,search,callers`
`CODEGRAPH_EXPLORE_LINENUMS`	Set to `0` to disable line numbers
`CODEGRAPH_NO_DAEMON`	Disable background daemon (sandboxed environments)
`CODEGRAPH_TELEMETRY`	Set to `0` to disable telemetry
`DO_NOT_TRACK`	Also disables telemetry
`CODEGRAPH_DAEMON_IDLE_TIMEOUT_MS`	Daemon idle timeout

Benchmark: 89% fewer tool calls, 60% cheaper, 69% fewer tokens vs. unassisted agent (validated on 7 repos)

Agent Usage Guidance

When CodeGraph's MCP server is active:

Call codegraph_explore FIRST for any structural/flow question — it returns verbatim source grouped by file, call paths, and blast radius. Usually the only call needed.
Treat returned source as already Read — do NOT re-open those files with the Read tool.
For a flow question ("how does X reach Y"), name the symbols spanning the flow in the query (e.g. mutateElement renderScene). CodeGraph surfaces the path between them, including dynamic-dispatch hops.
For reading a file or symbol, use codegraph_explore with its name/path — you get line-numbered source (safe to Edit from) plus impact info.
Don't grep then Read — one codegraph_explore replaces the entire search+read loop.
After edits, check the staleness banner — files listed as pending need a direct Read; everything else is fresh.
Monorepo support: pass projectPath to query a specific sub-project that has a .codegraph/ index.
