Git MCP Server

A Model Context Protocol (MCP) server for local Git operations with security and validation.

Features

• 🔒 Secure: Path traversal protection and input validation
• ✅ Validated: Runtime Zod validation for all inputs
• ⏱️ Timeout Protection: Configurable timeouts prevent indefinite blocking
• 🛠️ Complete: 15 Git operations supported
• 📝 Well-tested: Comprehensive integration test suite

Available Tools

• git_clone: Clone a Git repository
• git_status: Get the status of the repository
• git_diff: Get the diff of the repository (supports staged files)
• git_list_branches: List local and remote branches
• git_checkout: Switch between branches and update files
• git_list_files: List files in the repository
• git_read_file: Read the content of a file (with path traversal protection)
• git_add: Add files to the staging area
• git_reset: Reset current HEAD to the specified state (supports soft, mixed, hard)
• git_pull: Pull changes from remote (uses rebase)
• git_commit: Commit changes to the repository
• git_push: Push changes to remote (automatically performs pull --rebase first)
• git_log: Get the commit log of the repository

    }
  }
}

Usage Examples

Clone a Repository

{
  "tool": "git_clone",
  "arguments": {
    "repoUrl": "https://github.com/user/repo.git",
    "localPath": "/path/to/local/repo"
  }
}

Read a File

{
  "tool": "git_read_file",
  "arguments": {
    "repoPath": "/path/to/repo",
    "filePath": "src/index.ts"
  }
}

Create and Checkout a Branch

{
  "tool": "git_create_branch",
  "arguments": {
    "repoPath": "/path/to/repo",
    "branch": "feature/new-feature",
    "checkout": true
  }
}

Security

• Path Traversal Protection: File paths are validated to prevent access outside the repository
• Input Validation: All inputs are validated with Zod schemas before processing
• Error Handling: Proper error context preservation throughout the stack
• Timeout Protection: Operations have configurable timeouts (30s default, 60s for clone)

Testing

Run the integration test suite to verify all Git tools work correctly:

npx tsx test_script.ts

The script creates temporary local repositories, exercises all 15 tools plus error handling scenarios, and cleans up automatically.

Troubleshooting

Error: "Path does not exist"

Ensure the repository path exists and is accessible.

Error: "File path must be within the repository"

The requested file path is outside the repository boundaries. This is a security feature to prevent directory traversal attacks.

Timeout errors

Operations have a 30-second timeout by default (60 seconds for clone). For very large repositories or slow networks, operations may timeout. This is a safety feature to prevent indefinite blocking.

Error: "Git pull --rebase failed"

The rebase was automatically aborted to restore the repository to a clean state. Check for uncommitted changes or conflicts.
