Implementation Reference

• src/gis_mcp/shapely_functions.py:189-203 (handler)

  The main handler function for the 'convex_hull' MCP tool, decorated with @gis_mcp.tool(). It takes a WKT geometry string, computes its convex hull using Shapely, and returns the result as WKT.
  @gis_mcp.tool() def convex_hull(geometry: str) -> Dict[str, Any]: """Calculate convex hull of a geometry.""" try: from shapely import wkt geom = wkt.loads(geometry) result = geom.convex_hull return { "status": "success", "geometry": result.wkt, "message": "Convex hull created successfully" } except Exception as e: logger.error(f"Error creating convex hull: {str(e)}") raise ValueError(f"Failed to create convex hull: {str(e)}")
• src/gis_mcp/shapely_functions.py:24-37 (helper)

  Resource handler that lists 'convex_hull' as one of the available geometric property operations.
  @gis_mcp.resource("gis://operations/geometric") def get_geometric_properties() -> Dict[str, List[str]]: """List available geometric property operations.""" return { "operations": [ "convex_hull", "envelope", "minimum_rotated_rectangle", "get_centroid", "get_bounds", "get_coordinates", "get_geometry_type" ] }
