create-point
Generate point geometries from coordinates using PostGIS MCP Server. Input longitude and latitude to create spatial data with an optional SRID for custom projection.

Implementation Reference
- server.js:250-271 (handler)Handler for 'create-point' tool: validates input using CreatePointSchema, executes PostGIS query with ST_MakePoint to create point geometry, returns WKT, GeoJSON, coordinates, and SRID.
case "create-point": { const { longitude, latitude, srid } = CreatePointSchema.parse(args); const result = yield client.query(` SELECT ST_AsText(ST_SetSRID(ST_MakePoint($1, $2), $3)) as wkt, ST_AsGeoJSON(ST_SetSRID(ST_MakePoint($1, $2), $3)) as geojson `, [longitude, latitude, srid]); const response = { wkt: result.rows[0].wkt, geojson: JSON.parse(result.rows[0].geojson), coordinates: [longitude, latitude], srid: srid, }; return { content: [ { type: "text", text: JSON.stringify(response, null, 2), }, ], }; } - server.js:21-25 (schema)Zod validation schema for 'create-point' tool inputs: requires longitude and latitude (numbers), optional srid (default 4326).
const CreatePointSchema = zod_1.z.object({ longitude: zod_1.z.number(), latitude: zod_1.z.number(), srid: zod_1.z.number().optional().default(4326), }); - server.js:81-102 (registration)Registration of 'create-point' tool in ListTools handler: specifies name, description, and input schema matching the Zod schema.
