Implementation Reference
- src/index.ts:317-344 (handler)The main handler function for the 'wkt_to_geojson' tool. Parses WKT string using the 'wellknown' library and returns the resulting GeoJSON as a formatted JSON string.
async wktToGeoJSON(args: any): Promise<ToolResponse> { const { wkt } = args; if (!wkt) { throw new McpError( ErrorCode.InvalidParams, 'Missing required parameter: wkt' ); } try { console.error(`[Converting] WKT to GeoJSON: "${wkt.substring(0, 50)}${wkt.length > 50 ? '...' : ''}"`); const geojson = wellknown.parse(wkt); if (!geojson) { throw new Error('Failed to parse WKT string'); } return this.formatToolResponse(JSON.stringify(geojson, null, 2)); } catch (error) { console.error('[Error] WKT to GeoJSON conversion failed:', error); throw new McpError( ErrorCode.InternalError, `WKT to GeoJSON conversion failed: ${error instanceof Error ? error.message : String(error)}` ); } } - src/index.ts:92-104 (schema)Defines the input schema and metadata for the 'wkt_to_geojson' tool in the ListTools response.

case 'wkt_to_geojson': return await this.wktToGeoJSON(request.params.arguments); - src/index.ts:63-72 (helper)Helper method used by the handler to format the GeoJSON response according to MCP ToolResponse type.
