Local Git MCP server

This MCP Git server is a Python-based solution for managing local Git repositories through a Message-based Communication Protocol framework. It enables creating, managing, and performing various Git operations on local repositories through a standardized interface.

Installation and Setup

Prerequisites

Before installing the MCP Git server, ensure you have the following dependencies:

• Python (3.6 or higher recommended)
• GitPython
• Pydantic
• MCP Server

Installation Steps

1. Install the required dependencies:

pip install gitpython pydantic mcp-server

2. Clone or download the MCP Git server code to your local machine.

Running the Server

The server can be started with a simple command, with an optional parameter to specify the directory where repositories will be stored:

python git_server.py [--repositories-dir ./repositories]

By default, the server will create and manage repositories in the ./repositories directory if not specified otherwise.

Using the Git Server

Available Operations

The MCP Git server supports the following Git operations:

• Repository creation - initialize new Git repositories
• Adding files - stage changes to files
• Committing changes - create commits with messages
• Pulling and pushing - sync with remote repositories
• Diff generation - view differences between commits

Repository Naming

The server validates repository names to ensure they follow Git's naming conventions. When creating a new repository, make sure to use valid names to avoid errors.

Example Commands

While the specific API endpoints will depend on your MCP client implementation, here are the core operations you can perform:

Creating a New Repository

# Example client code to create a new repository
client.create_repository(name="my-project")

Adding Files to a Repository

# Example client code to add files
client.add_files(repository="my-project", files=["file1.txt", "file2.txt"])

Committing Changes

# Example client code to commit changes
client.commit(
    repository="my-project", 
    message="Initial commit", 
    author_name="User Name", 
    author_email="[email protected]"
)

Generating Diffs

# Example client code to generate a diff between commits
diff = client.diff(
    repository="my-project", 
    from_commit="abc123", 
    to_commit="def456"
)

Server Configuration

The server can be configured through command-line arguments:

• --repositories-dir: Directory where Git repositories will be stored
• Additional MCP server configuration options (refer to MCP server documentation)

The repositories directory will be created automatically if it doesn't exist when the server starts.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "local-git" '{"command":"python","args":["git_server.py"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "local-git": {
            "command": "python",
            "args": [
                "git_server.py"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "local-git": {
            "command": "python",
            "args": [
                "git_server.py"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
