Implementation Reference
- src/gis_mcp/shapely_functions.py:205-219 (handler)The core handler function for the 'envelope' MCP tool, which computes the bounding box (envelope) of an input geometry provided as WKT string using Shapely library and returns the result as WKT with status information.
@gis_mcp.tool() def envelope(geometry: str) -> Dict[str, Any]: """Get bounding box of a geometry.""" try: from shapely import wkt geom = wkt.loads(geometry) result = geom.envelope return { "status": "success", "geometry": result.wkt, "message": "Envelope created successfully" } except Exception as e: logger.error(f"Error creating envelope: {str(e)}") raise ValueError(f"Failed to create envelope: {str(e)}")
