for server in result['servers']:
    print(f"{server.name}: {server.description}")

# Get server details
server = api.get_server_details("ai.waystation/gmail")
print(f"Status: {server.status}")
if server.packages:
    print("Available packages:")
    for pkg in server.packages:
        print(f"  - {pkg.get('registry')}: {pkg.get('package')}")

Troubleshooting

Virtual Environment Issues

If you encounter permission errors, ensure you're using a virtual environment:

python3 -m venv mcp-registry-env
source mcp-registry-env/bin/activate
pip install --upgrade pip
pip install mcp-registry-cli

Package Installation

If server installation fails, check that you have the required package manager:

• npm servers: Ensure Node.js and npm are installed
• pip servers: Ensure Python and pip are available
• Use --dry-run to preview commands before execution

API Issues

If you encounter API errors:

• Check your internet connection
• The MCP Registry API may be temporarily unavailable
• Try reducing the --limit parameter
