Basic information
CodeGraphX (CGX) — a local, token-efficient codebase graph engine & MCP server for AI coding agents. Tree-sitter parsing, a bi-temporal SQLite semantic graph, O(1) symbol lookup, and impact/blast-radius tracing so agents answer 'what breaks if I change this?' in a few hundred tok
Add this server to your MCP-compatible client using the configuration below.

}Get the current status of the CodeGraphX graph.
List all files in the codebase.
Provides a high-level summary of a symbol's blast radius (upstream/downstream).
Instantly check if a symbol exists using a Bloom filter.
High-level tool to verify if a specific task description has been implemented in a commit.
Get a summary of changes in the current session or a specific branch.
CodeGraphX (CGX) is a local, token-efficient codebase graph engine for AI coding agents and human developers. It parses source code with Tree-sitter, stores a bi-temporal semantic graph in SQLite, and serves it over a CLI and an MCP server.
Install with npm install -g codegraphx, then run cgx init to index the codebase. Query symbols with cgx query <symbol> or trace impact with cgx impact. The MCP server (cgx-mcp) exposes six tools for AI agents, with zero-config auto-indexing on first start.
A Language Server answers "go to definition" for editors; grep finds text, not structure. CodeGraphX answers structural, whole-repo reasoning questions like blast radius and dependency cycles, optimized for AI agents with token-efficient output.
100% local. No cloud, no telemetry, no network — code never leaves the machine.
Python, JavaScript, JSX, TypeScript, TSX, HTML, and CSS. It extracts functions, classes, calls, imports, and framework-specific patterns (Flask/FastAPI, Express, fetch/axios).
Run `cgx init` or `cgx scan` to perform a full re-index (unchanged files are served from cache). Use `cgx watch` for automatic re-indexing on file changes.
Node.js version 18 or higher, running in a CommonJS environment.
