What is the RepoMapper MCP server?

Repomapper mcp server lets Claude, Cursor and other MCP clients work with RepoMapper directly. RepoMap is a powerful tool designed to help, primarily LLMs, understand and navigate complex codebases. It functions both as a command-line application for on-demand analysis and as an MCP (Model Context Protocol) server, providing continuous repository mapping capabilities to other applications.

What RepoMapper does

RepoMap is a powerful tool designed to help, primarily LLMs, understand and navigate complex codebases. It functions both as a command-line application for on-demand analysis and as an MCP (Model Context Protocol) server, providing continuous repository mapping capabilities to other applications. By generating a "map" of the software repository, RepoMap highlights important files, code definitions, and their relationships. It leverages Tree-sitter for accurate code parsing and the PageRank algorithm to rank code elements by importance, ensuring that the most relevant information is always prioritized.

Key capabilities

  • Smart Code Analysis — Uses Tree-sitter to parse source code and extract function/class definitions
  • Relevance Ranking — Employs PageRank algorithm to rank code elements by importance
  • Token-Aware — Respects token limits to fit within LLM context windows
  • Caching — Persistent caching for fast subsequent runs
  • Multi-Language — Supports Python, JavaScript, TypeScript, Java, C/C++, Go, Rust, and more
  • Important File Detection — Automatically identifies and prioritizes important files (README, requirements.txt, etc.)

Tools it exposes

Once connected, the assistant can call these 2 tools directly:

  • Setup — 1. The RepoMap MCP server uses STDIO (standard input/output) for communication. No additional configuration is required for the transport layer. 2. To set up
  • Usage — 2. The server will start and listen for requests via STDIO. 3. Other applications can then use the repo_map tool provided by the server to generate repository

Installing the repomapper mcp server

Setup follows the standard MCP pattern: clone or install the server, then register it in your client's configuration file and restart the client. The configuration snippets on this page cover Claude Desktop, Claude Code and Cursor.

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. RepoMapper sits in that group, and the shape of its toolset — Setup, Usage — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • Maintained by pdavis68, written in Python.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the repomapper mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.

Available tools

Setup1. The RepoMap MCP server uses STDIO (standard input/output) for communication. No additional configuration is required for the transport layer. 2. To set up RepoMap as an MCP server with Cline (or similar tools like Roo
Usage2. The server will start and listen for requests via STDIO. 3. Other applications can then use the repo_map tool provided by the server to generate repository maps. They must specify the project_root parameter as an abso

How to install the RepoMapper MCP server

{
  "mcpServers": {
    "RepoMapper": {
      "disabled": false,
      "timeout": 60,
      "type": "stdio",
