rag-rat MCP

rag-rat is a local, read-only repository intelligence MCP server that provides coding agents with a code graph, history, and memory. It indexes source code using tree-sitter and embeddings, builds a caller/callee graph, and offers 47 tools for semantic search, impact analysis, and provenance-backed answers. It supports parallel worktrees and persists typed memories across sessions.
