codegraph-mcp
codegraph-mcp
Knowledge-Graph MCP Server für GitHub-Repositories. Nimmt den Code jedes GitHub-Repos in einen Neo4j-Graphen auf (Knoten für Repository / Datei / Funktion; Kanten CONTAINS / DEFINES / IMPORTS / CALLS) und stellt diesen Graphen als schreibgeschützte MCP-Tools für jeden MCP-Host bereit – Claude Desktop, opencode, Cursor oder jeden Client, der das Model Context Protocol unterstützt.
Status
v0.1 – stdio-Transport, Neo4j 5.x-Backend, Python ast + tree-sitter (JS/TS/TSX)-Parsing.

Schnellstart
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"Ein Repository erfassen
uv run codegraph ingest https://github.com/<owner>/<name>
# → {"graph_id": "owner/name", "files": 142, "functions": 880, ...}Einen MCP-Host verbinden
