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).
