mcp-server-git: A git MCP server

Overview

A Model Context Protocol server for Git repository interaction and automation. This server provides tools to read, search, and manipulate Git repositories via Large Language Models.

Please note that mcp-server-git is currently in early development. The functionality and available tools are subject to change and expansion as we continue to develop and improve the server.

Installation

Using uv (recommended)

When using uv no specific installation is needed. We will use uvx to directly run mcp-server-git.

Using PIP

Alternatively you can install mcp-server-git via pip:

pip install mcp-server-git

After installation, you can run it as a script using:

python -m mcp_server_git

Configuration

Usage with Claude Desktop

Add this to your claude_desktop_config.json:

"mcpServers": {
  "git": {
    "command": "uvx",
    "args": ["mcp-server-git", "--repository", "path/to/git/repo"]
  }
}

"mcpServers": {
  "git": {
    "command": "docker",
    "args": ["run", "--rm", "-i", "--mount", "type=bind,src=/Users/username,dst=/Users/username", "mcp/git"]
  }
}

"mcpServers": {
  "git": {
    "command": "python",
    "args": ["-m", "mcp_server_git", "--repository", "path/to/git/repo"]
  }
}

Usage with Zed

Add to your Zed settings.json:

"context_servers": [
  "mcp-server-git": {
    "command": {
      "path": "uvx",
      "args": ["mcp-server-git"]
    }
  }
],

"context_servers": {
  "mcp-server-git": {
    "command": {
      "path": "python",
      "args": ["-m", "mcp_server_git"]
    }
  }
},

Debugging

You can use the MCP inspector to debug the server. For uvx installations:

npx @modelcontextprotocol/inspector uvx mcp-server-git

Or if you've installed the package in a specific directory or are developing on it:

cd path/to/servers/src/git
npx @modelcontextprotocol/inspector uv run mcp-server-git

Running tail -n 20 -f ~/Library/Logs/Claude/mcp*.log will show the logs from the server and may help you debug any issues.

Development

If you are doing local development, there are two ways to test your changes:

1. Run the MCP inspector to test your changes. See Debugging for run instructions.

2. Test using the Claude desktop app. Add the following to your claude_desktop_config.json:

Docker

{
  "mcpServers": {
    "git": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "--mount", "type=bind,src=/Users/username/Desktop,dst=/projects/Desktop",
        "--mount", "type=bind,src=/path/to/other/allowed/dir,dst=/projects/other/allowed/dir,ro",
        "--mount", "type=bind,src=/path/to/file.txt,dst=/projects/path/to/file.txt",
        "mcp/git"
      ]
    }
  }
}

UVX

{
"mcpServers": {
  "git": {
    "command": "uv",
    "args": [ 
      "--directory",
      "/<path to mcp-servers>/mcp-servers/src/git",
      "run",
      "mcp-server-git"
    ]
  }
}

Build

Docker build:

cd src/git
docker build -t mcp/git .
