Quick Start

  1. Clone and install:

    git clone https://github.com/FradSer/mcp-server-git-cz.git
cd mcp-server-git-cz
uv venv && uv pip install -r requirements.txt

  2. Configure environment:

    cp .env.example .env
# Edit .env with your API keys

  3. Run the server:

    uv run mcp-server-git-cz

Installation

Prerequisites

Step-by-step Installation

  1. Clone the repository:

    git clone https://github.com/FradSer/mcp-server-git-cz.git
cd mcp-server-git-cz

  2. Create virtual environment and install dependencies:

    uv venv
uv pip install -r requirements.txt

  3. Set up environment variables:

    cp .env.example .env

    Edit .env file:

    DEEPSEEK_API_KEY=your_deepseek_api_key
GROQ_API_KEY=your_groq_api_key
LLM_PROVIDER=deepseek  # or groq

Configuration

Environment Variables

VariableDescriptionDefaultRequired
DEEPSEEK_API_KEYDeepSeek API key-Yes (if using DeepSeek)
GROQ_API_KEYGroq API key-Yes (if using Groq)
LLM_PROVIDERLLM provider to usedeepseekNo

Transport Options

The server supports multiple transport methods:

# STDIO transport (recommended)
uv run mcp-server-git-cz

# SSE transport
uv run mcp-server-git-cz --transport sse --port 8000

Usage

The server exposes a single tool: generate_commit_message that analyzes your git diff and generates conventional commit messages.

Basic Example

import asyncio
from mcp.client.session import ClientSession
from mcp.client.stdio import StdioServerParameters, stdio_client

async def main():
    async with stdio_client(
        StdioServerParameters(command="uv", args=["run", "mcp-server-git-cz"])
    ) as (read, write):
        async with ClientSession(read, write) as session:
            await session.initialize()
            
            # Generate commit message
            result = await session.call_tool("generate_commit_message", {})
            print(result)

asyncio.run(main())

MCP Client Setup

Note: Replace /path/to/mcp-server-git-cz with your actual project directory path in all configurations below.

Claude Code

# Project scope (recommended for teams)
claude mcp add git-cz -s project -- uv run --python /path/to/mcp-server-git-cz/.venv/bin/python -m mcp_server_git_cz

# User scope (personal use)
claude mcp add git-cz -s user -- uv run --python /path/to/mcp-server-git-cz/.venv/bin/python -m mcp_server_git_cz

Cursor

Add to Cursor settings:

{
  "mcpServers": {
    "git-cz": {
      "command": "uv",
      "args": ["run", "--python", "/path/to/mcp-server-git-cz/.venv/bin/python", "-m", "mcp_server_git_cz"],
      "env": {},
      "transport": "stdio"
    }
  }
}

Gemini CLI

Add to ~/.gemini/settings.json:

{
  "mcpServers": {
    "git-cz": {
      "command": "uv",
      "args": ["run", "--python", "/path/to/mcp-server-git-cz/.venv/bin/python", "-m", "mcp_server_git_cz"],
      "env": {}
    }
  }
}

Finding Your Paths

  1. Get virtual environment path:

    cd mcp-server-git-cz
uv venv
which python  # Copy this path

  2. Get project directory:

    pwd  # Copy this path

  3. Update configurations with your actual paths

Advanced Configuration

With Environment Variables

{
  "mcpServers": {
    "git-cz": {
      "command": "uv",
      "args": ["run", "--python", "/path/to/mcp-server-git-cz/.venv/bin/python", "-m", "mcp_server_git_cz"],
      "env": {
        "DEEPSEEK_API_KEY": "your_key_here",
        "LLM_PROVIDER": "deepseek"
      }
    }
  }
}

With Working Directory

{
  "mcpServers": {
    "git-cz": {
      "command": "uv",
      "args": ["run", "--python", "/path/to/mcp-server-git-cz/.venv/bin/python", "-m", "mcp_server_git_cz"],
      "cwd": "/path/to/mcp-server-git-cz",
      "env": {}
    }
  }
}

Examples

Using with MCP Clients

Once configured, you can interact with the tool using natural language:

  • "Generate a commit message for my current changes"
  • "Create a conventional commit message based on my git diff"
  • "Help me write a commit message following conventional commits"

The server will:

  1. Analyze your current git diff
  2. Generate a conventional commit message using AI
  3. Return the formatted message for review

Example Output

feat(auth): add OAuth2 integration with GitHub

- Implement OAuth2 authentication flow
- Add GitHub provider configuration
- Update user model to support external auth
- Add tests for authentication endpoints

Closes #123
