pitlane-mcp

Overview

pitlane-mcp is a production-ready MCP server designed to reduce token usage in AI coding agents by providing AST-based code indexing. It supports multiple programming languages and implements a sophisticated symbol-based navigation system that allows agents to retrieve only the code portions they actually need, rather than processing entire files. The solution includes BM25 symbol search, optional semantic search, and tools for code investigation, location, tracing, and impact analysis.

After installing, here are 5 things you can ask your AI assistant:

• ensure_project_ready

  Ensures the index exists and reports whether embeddings are still running.

  Try:Make sure the project is indexed and readyTry:Check if the codebase is ready for analysis
• investigate

  Provides broad code intelligence for subsystem, behavior, and execution-path questions.

  Try:How does authentication work in this codebase?Try:Explain the user flow in this application
• locate_code

  Helps discover code symbols and files without reading full source.

  Try:Find the user authentication moduleTry:Locate the payment processing code
• read_code_unit

  Reads a specific code unit once the target is known.

  Try:Show me the implementation of the login functionTry:Display the User class definition
• trace_path

  Traces execution paths and source-to-sink relationships.

  Try:Trace the execution path from API endpoint to databaseTry:Follow the flow from configuration loading to effect
• analyze_impact

  Analyzes impact before making edits or refactors.

  Try:What would be affected by changing this API?Try:Identify all references to this function
• get_index_stats

  Provides statistics about the codebase index.

  Try:Show me index statisticsTry:How many symbols are indexed?
• search_content

  Searches for text fragments within the codebase.

  Try:Find all occurrences of 'TODO'Try:Search for 'database connection' in the code

pitlane-mcp supports Rust, Python, JavaScript, TypeScript, Svelte, C, C++, Go, Java, C#, Bash, Ruby, Swift, Objective-C, PHP, Zig, Lua, Kotlin, and Solidity.

How does pitlane-mcp reduce token usage?

It indexes code once with tree-sitter and lets agents retrieve only the symbols they need instead of dumping whole files into context, reducing prompt footprint by one or two orders of magnitude.
