Git Helper MCP

A Model Context Protocol (MCP) server that provides git repository tools for Claude.

Features

This MCP provides the following tools:

• get_status - Get current repository status (staged, unstaged, untracked files)

• list_branches - List all branches with current branch highlighted

• get_commit_history - View recent commits with messages and authors

• get_branch_info - Get detailed info about current or specific branch

• get_diff - Show changes (staged or unstaged)

Installation

1. Create a virtual environment and install dependencies:

   python3 -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate
   pip install -r requirements.txt

2. Test the server:

   python server.py

Configuration for Claude Desktop

Add this to your Claude Desktop MCP settings file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "git-helper": {
      "command": "/Users/prateek/Code/claude/git-helper-mcp/venv/bin/python",
      "args": ["/Users/prateek/Code/claude/git-helper-mcp/server.py"]
    }
  }
}

After adding, restart Claude Desktop.

Usage Examples

Once configured, you can ask Claude things like:

• "What's the status of my git repository?"

• "Show me the recent commit history"

• "List all branches"

• "What branch am I on?"

• "Show me the unstaged changes"

• "What's in my staging area?"

How It Works

The MCP server runs as a separate process and communicates with Claude via stdio. When you ask git-related questions, Claude can call these tools to get real-time information from your git repository.

Requirements

• Python 3.10+

• Git installed and in PATH
