codedb-mcp Fast Code Intelligence

Skill by ara.so — MCP Skills collection.

Overview

codedb-mcp (also called codebase-mcp) is a Rust-based MCP server that turns any local repository into a persistent code intelligence service. It maintains a tree-sitter indexed database under .codedb-mcp/ with symbols, references, dependencies, graph metadata, lexical indexes, and vector embeddings for fast semantic search.

Key capabilities:

• Millisecond-latency warm queries — 20,000x faster than rg on indexed searches
• Answer-oriented context tools — codedb_context and codedb_explore return ranked relevant code without dumping entire files
• Dependency-aware module discovery — Automatic grouping of related files based on dependency graphs
• LSP-like features — Symbol definitions, callers, outlines, and reference navigation
• Code Module Atlas — Visual 3D browser showing file relationships and module boundaries
• DeepWiki — Auto-generated repository documentation with cited sources
• Local-first — All data stored in project .codedb-mcp/ directory, no cloud dependencies
