Lain MCP

A high-performance knowledge graph MCP server for AI coding agents. It indexes code to map callers, dependencies, symbols, and Git co-changes, enabling semantic search and blast radius analysis. The persistent index stays on disk between runs and supports integration with various coding agents like Claude Code, Cursor, and VS Code.
