Implementation Reference
- server.js:352-376 (handler)Executes the transform-coordinates tool: validates input using TransformCoordinatesSchema, runs PostGIS ST_Transform query to convert geometry from source_srid to target_srid, returns transformed WKT and GeoJSON.
case "transform-coordinates": { const { geometry_wkt, source_srid, target_srid } = TransformCoordinatesSchema.parse(args); const result = yield client.query(` SELECT ST_AsText(ST_Transform(ST_GeomFromText($1, $2), $3)) as transformed_wkt, ST_AsGeoJSON(ST_Transform(ST_GeomFromText($1, $2), $3)) as transformed_geojson, $2 as source_srid, $3 as target_srid `, [geometry_wkt, source_srid, target_srid]); const response = { original_geometry: geometry_wkt, source_srid: source_srid, target_srid: target_srid, transformed_wkt: result.rows[0].transformed_wkt, transformed_geojson: JSON.parse(result.rows[0].transformed_geojson), }; return { content: [ { type: "text", text: JSON.stringify(response, null, 2), }, ], }; } - server.js:44-48 (schema)Zod schema defining input parameters for the transform-coordinates tool: geometry_wkt (string), source_srid (number), target_srid (number).
const TransformCoordinatesSchema = zod_1.z.object({ geometry_wkt: zod_1.z.string(), source_srid: zod_1.z.number(), target_srid: zod_1.z.number(), }); - server.js:145-157 (registration)Registers the transform-coordinates tool in the ListTools response, including name, description, and input schema matching the Zod schema.
