Step 1: Convert the location to precise latitude/longitude coordinates. Step 2: Use the lat-lng-to-tile tool to convert the coordinates to tile coordinates (x, y) for zoom level ${zoomLevel}. Step 3: Use the map-tiles tool with the calculated x, y coordinates and zoom level ${zoomLevel}, using "${scale}" scale. Set fetch_image=true to retrieve the actual tile image for visual analysis. Step 4: Analyze the geological map tile image to identify: - Rock unit colors and patterns - Geological formations and structures - Fault lines and other linear features - Age relationships between units Step 5: Consider getting adjacent tiles (x±1, y±1) with fetch_image=true to show a broader geological context. Step 6: Provide both the tile URLs and detailed analysis of the geological features visible in the map images.` } } ] }; }); return server.server; } import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js"; // STDIO transport support for Claude Desktop // Check if this file is being run directly (not imported) if (process.argv[1] && process.argv[1].endsWith('index.js')) { // This runs when executed directly with node (STDIO mode) const server = createServer({ config: {} }); const transport = new StdioServerTransport(); server.connect(transport).catch((error) => { console.error("Failed to start STDIO server:", error); process.exit(1); }); }
