• src/gis_mcp/shapely_functions.py:559-580 (handler)

  The main handler function for the 'geometry_to_geojson' tool, decorated with @gis_mcp.tool() for MCP registration. Converts WKT geometry to GeoJSON using Shapely's mapping.
  @gis_mcp.tool() def geometry_to_geojson(geometry: str) -> Dict[str, Any]: """ Convert a Shapely geometry (WKT) to GeoJSON using shapely.geometry.mapping. Args: geometry: WKT string of the geometry. Returns: Dictionary with status, message, and GeoJSON representation. """ try: from shapely import wkt from shapely.geometry import mapping geom = wkt.loads(geometry) geojson = mapping(geom) return { "status": "success", "geojson": geojson, "message": "Geometry converted to GeoJSON successfully" } except Exception as e: logger.error(f"Error in geometry_to_geojson: {str(e)}") return {"status": "error", "message": str(e)}
• src/gis_mcp/shapely_functions.py:82-93 (helper)

  Resource handler listing 'geometry_to_geojson' among available Shapely utility operations.
