Development

# Install dependencies
uv pip install -r requirements.txt

# Run in dev mode with Inspector
mcp dev git_mcp/server.py

Testing

The project includes two test scripts:

1. test_git_mcp.py - Tests the underlying Git command functionality directly, without using the MCP server.
2. test_mcp_server.py - Tests the MCP server functionality by starting a server instance and making calls to it.

To run the tests:

# Test the Git command functionality
python test_git_mcp.py

# Test the MCP server (requires the git-mcp package to be installed)
python test_mcp_server.py
