Repo Lens MCP Server

Search functions, classes and API routes across all your local repositories at once, by structure not text.

LABSCO SUMMARY

Structural search, deliberately not a file toolkit.

It does one thing your assistant's built-in tools cannot: reach outside the current repository and find a definition by shape rather than by string. The AST pass is what makes the answers usable — you get the signature and whether it is exported, not a grep hit you have to open. Text search and file reads inside the repo you are already in are left to the tools that are better at them.

What it is

A search server for the case your editor cannot cover: you are in the frontend repo and the answer is in the backend one. It parses code with ast-grep rather than matching text, so it can tell class User from const User and return a full signature instead of a line. JavaScript, TypeScript and PHP are supported, across repositories you register once or directories you pass ad hoc.

What you get

  • repolens_find_functions finds function and method definitions, wildcards included, in JS/TS and PHP
  • repolens_find_classes finds class definitions, and PHP traits
  • repolens_find_types finds interfaces and type aliases
  • repolens_find_api_routes maps API endpoints across Express, NestJS, Fastify and Laravel
  • repolens_list_repositories lists what is registered
  • Every search tool takes paths for ad-hoc directories and repoFilter to narrow to registered repos by alias

Requirements

Run it with npx -y repo-lens-mcp (package repo-lens-mcp, version 0.3.0) over stdio. No account, no key, nothing leaves the machine. A repolens.yaml listing repository paths and aliases is optional — pass --config to point at one, or drop it at ~/.config/repo-lens-mcp/repolens.yaml; without it the ad-hoc paths parameter still works. MCP_LOG_LEVEL controls logging.

Setup effort

One command — npx repo-lens-mcp
