codegraph-mcp

Servidor MCP de Grafo de Conocimiento para repositorios de GitHub. Ingiere el código de cualquier repositorio de GitHub en un grafo de Neo4j (nodos: Repositorio / Archivo / Función; aristas: CONTAINS / DEFINES / IMPORTS / CALLS) y expone dicho grafo como herramientas MCP de solo lectura a cualquier host MCP: Claude Desktop, opencode, Cursor o cualquier cliente que hable el Model Context Protocol.

Estado

v0.1 — transporte stdio, backend Neo4j 5.x, análisis con ast de Python + tree-sitter (JS/TS/TSX).

Related MCP server: NOMIK

Inicio rápido

git clone <codegraph-mcp> && cd codegraph-mcp
uv sync --extra dev              # all deps pinned via uv.lock
docker compose up -d             # Neo4j on bolt://localhost:7687
cp .env.example .env
uv run pytest -m "not slow and not integration"

Ingresar un repositorio

uv run codegraph ingest https://github.com/<owner>/<name>
# → {"graph_id": "owner/name", "files": 142, "functions": 880, ...}
