MCP Git Repo Browser (Node.js)

A Node.js implementation of a Git repository browser using the Model Context Protocol (MCP).

Configuration

Add this to your MCP settings configuration file:

{
    "mcpServers": {
        "mcp-git-repo-browser": {
            "command": "node",
            "args": ["/path/to/mcp-git-repo-browser/src/index.js"]
        }
    }
}

Features

The server provides two main tools:

1. git_directory_structure: Returns a tree-like representation of a repository’s directory structure

   • Input: Repository URL
   • Output: ASCII tree representation of the repository structure

2. git_read_important_files: Reads and returns the contents of specified files in a repository

   • Input: Repository URL and list of file paths
   • Output: Dictionary mapping file paths to their contents

Implementation Details

• Uses Node.js native modules (crypto, path, os) for core functionality
• Leverages fs-extra for enhanced file operations
• Uses simple-git for Git repository operations
• Implements clean error handling and resource cleanup
• Creates deterministic temporary directories based on repository URL hashes
• Reuses cloned repositories when possible for efficiency

Requirements

• Node.js 14.x or higher
• Git installed on the system

Installation

git clone <repository-url>
cd mcp-git-repo-browser
npm install

Usage

Start the server:

node src/index.js

The server runs on stdio, making it compatible with MCP clients.
