What is LAIN-mcp?
LAIN-mcp is a Rust MCP server that gives AI coding agents real architectural awareness of your codebase — not just line-by-line search, but system-wide understanding.
Built to solve a real problem: navigating large codebases with AI agents burns token budgets fast. LAIN-mcp fixes that by maintaining a persistent knowledge graph of your code, so agents understand structure and impact before making changes.
Key Features
- Blast radius analysis — know what breaks before you change anything
- Knowledge graph — persistent, queryable map of every symbol and relationship in your codebase
- Co-change detection — git history analysis to find files that evolve together
- Local semantic search — ONNX embeddings, no API keys, no data leaving your machine
- Sub-millisecond graph queries — built in Rust with petgraph
- 21 MCP tools — architecture, search, impact analysis, and health monitoring
Why Rust?
Zero-cost abstractions, memory safety without GC, and sub-millisecond traversal for long-running agent processes.
Completely local
No cloud. No API keys. Your code never leaves your machine.
