codegraph-mcp
MCP-сервер графа знаний для репозиториев GitHub. Загружает код любого репозитория GitHub в граф Neo4j (узлы Repository / File / Function; ребра CONTAINS / DEFINES / IMPORTS / CALLS) и предоставляет этот граф в виде read-only MCP-инструментов любому MCP-хосту — Claude Desktop, opencode, Cursor или любому клиенту, поддерживающему Model Context Protocol.
Статус
v0.1 — транспорт stdio, backend Neo4j 5.x, парсинг с помощью Python ast + tree-sitter (JS/TS/TSX).
