Implementation Reference

aerospace_mcp/tools/propellers.py:210-225 (handler)

The main MCP tool handler function. Imports PROPELLER_DATABASE from integrations/propellers.py and returns it as a JSON-formatted string. Includes error handling for missing dependencies.

def get_propeller_database() -> str:
    """Get available propeller database with geometric and performance data.

    Returns:
        JSON string with propeller database
    """
    try:
        from ..integrations.propellers import PROPELLER_DATABASE

        return json.dumps(PROPELLER_DATABASE, indent=2)

    except ImportError:
        return "Propeller database not available"
    except Exception as e:
        logger.error(f"Propeller database error: {str(e)}", exc_info=True)

aerospace_mcp/fastmcp_server.py:108-108 (registration)
Registers the get_propeller_database tool function with the FastMCP server instance.
```
mcp.tool(get_propeller_database)
