Token-efficient code intelligence MCP server for AI coding agents.

`pitlane-mcp` indexes a codebase once with tree-sitter and lets agents retrieve the symbols they actually need instead of dumping whole files into context.

Project Status

`pitlane-mcp` is feature-complete and currently in maintenance mode. New major features are not actively planned. Bug fixes, compatibility updates, documentation improvements, and focused contributions are still welcome.

Why

AI coding agents tend to over-read. `pitlane-mcp` gives them a smaller navigation surface and symbol-level reads so they can:

• index code once
• discover the right symbol or file
• read the smallest useful unit
• trace execution paths and change impact

On the benchmark corpora in this repo, that translates into large reductions in prompt footprint, often by one or two orders of magnitude, while keeping navigation grounded in the codebase.

What It Does

• AST-based indexing for Rust, Python, JavaScript, TypeScript, Svelte, C, C++, Go, Java, C#, Ruby, Swift, Objective-C, PHP, Zig, Kotlin, Lua, Solidity, and Bash
• BM25 symbol search plus optional semantic search
• Small default MCP surface for agents
• Composite navigation tools for discovery, reading, path tracing, and impact analysis
• Incremental re-indexing and disk-persisted indexes
• Fully local operation with no required external service
