High-performance MCP server that indexes codebases into a persistent knowledge graph for AI coding agents.

45kMIT

High-performance code intelligence MCP server. Indexes codebases into a persistent knowledge graph — average repo in milliseconds. 158 languages, sub-ms queries, 99% fewer tokens. Single static binary, zero dependencies.

Pros

  • +Extremely fast indexing (Linux kernel in 3 minutes) with sub-millisecond queries
  • +Supports 162 languages via vendored tree-sitter grammars with no runtime dependencies
  • +Ships as a single static binary with 17 MCP tools and built-in 3D graph visualization
  • +Reduces token usage by up to 120x compared to file-by-file exploration

Cons

  • −Requires installing and configuring an MCP client/agent to use
  • −Hybrid LSP semantic resolution only covers 10 languages
  • −Writes to agent configuration files, which may require security review

Target audience: Developers and AI coding agent users who need fast, local code intelligence and structural queries over large codebases.
