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:

Using uvx

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

Using docker

• Note: replace '/Users/username' with a path that you want to be accessible by this tool

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

Using pip installation

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

Usage with VS Code

For quick installation, use one of the one-click install buttons below...

For manual installation, you can configure the MCP server using one of these methods:

Method 1: User Configuration (Recommended) Add the configuration to your user-level MCP configuration file. Open the Command Palette (Ctrl + Shift + P) and run MCP: Open User Configuration. This will open your user mcp.json file where you can add the server configuration.

Method 2: Workspace Configuration Alternatively, you can add the configuration to a file called .vscode/mcp.json in your workspace. This will allow you to share the configuration with others.

For more details about MCP configuration in VS Code, see the official VS Code MCP documentation.

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

For Docker installation:

{
  "mcp": {
    "servers": {
      "git": {
        "command": "docker",
        "args": [
          "run",
          "--rm",
          "-i",
          "--mount", "type=bind,src=${workspaceFolder},dst=/workspace",
          "mcp/git"
        ]
      }
    }
  }
}

Usage with Zed

Add to your Zed settings.json:

Using uvx

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

Using pip installation

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

Usage with Zencoder

1. Go to the Zencoder menu (...)
2. From the dropdown menu, select Agent Tools
3. Click on the Add Custom MCP
4. Add the name (i.e. git) and server configuration from below, and make sure to hit the Install button

Using uvx

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

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 .
