A Model Context Protocol (MCP) server that provides tools for interacting with Git repositories. This server allows AI assistants and LLM agents to manage repositories, branches, commits, and files through a standardized interface without requiring direct filesystem or command-line access. It exposes Git operations as MCP resources and tools while maintaining proper security boundaries.

Core Components:
- **MCP Server**: Uses the Model Context Protocol SDK to create a server that exposes resources and tools
- **Git Service**: Abstraction layer over simple-git to provide clean interfaces for Git operations
- **Resources**: Expose Git data through MCP resources with consistent URI templates
- **Tools**: Expose Git operations through MCP tools with well-defined schemas
- **Error Handling**: Standardized error handling and reporting
## Features
### Resource Access
Expose Git repository information through MCP resources:
- **Repository Information**: Access basic Git repository information including current branch, status, and reference details
- **Repository Branches**: List all branches in the repository with current branch indicator
- **Repository Remotes**: List all configured remote repositories with their URLs
- **Repository Tags**: List all tags in the repository with their references
- **File Content**: Access content of specific files at a given Git reference
- **Directory Listing**: View lists of files and directories at a specific path and reference
- **Diffs**: Get differences between references, unstaged changes, or staged changes
- **Commit History**: View detailed commit logs with author, date, and message information
- **File Blame**: See line-by-line attribution showing which commit last modified each line
- **Commit Details**: Access detailed information about specific commits including diff changes
### Git Operations
Execute Git commands through MCP tools:
- **Repository Operations**: Initialize repositories, clone from remotes, check repository status
- **Branch Operations**: Create branches, list branches, checkout, delete branches, merge
- **Working Directory Operations**: Stage files, unstage files, commit changes, create diffs
- **Remote Operations**: Add remotes, list remotes, fetch, pull, push
- **Advanced Operations**: Manage tags, stash changes, cherry-pick commits, rebase branches, reset, clean
## Installation
### Prerequisites
- Node.js 16 or higher
- Git installed and available in the PATH
### Install from NPM
```bash
npm install -g git-mcp-server
```
### Install from Source
```bash
git clone https://github.com/cyanheads/git-mcp-server.git
cd git-mcp-server
npm install
npm run build
```
## Usage
### Running the Server
```bash
git-mcp-server
```
The server communicates through stdin/stdout using the Model Context Protocol, making it compatible with any MCP client.
### Integration with Claude
Add to your Claude configuration file:
```json
{
"mcpServers": {
"git": {
"command": "git-mcp-server",
"args": [],
"env": {},
"disabled": false
}
}
}
```
### Integration with Other MCP Clients
Use the MCP inspector to test the server:
```bash
npx @modelcontextprotocol/inspector git-mcp-server
```
