searchLocation

Implementation Reference

• src/index.js:48-74 (registration)

  Registration of the 'searchLocation' MCP tool, including input schema and handler function.

  server.tool(
    "searchLocation",
    { locationName: z.string().describe("The name of the location to search for") },
    async ({ locationName }) => {
      const locations = await searchLocation(locationName);
      
      if (locations.length === 0) {
        return {
          content: [{ 
            type: "text", 
            text: `No locations found for "${locationName}".` 
          }]
        };
      }
  
      const formattedLocations = locations.map(loc => 
        `${loc.name}${loc.plz ? ` (${loc.plz})` : ''}, ${loc.land} - ID: ${loc.id}`
      ).join('\n');
  
      return {
        content: [{ 
          type: "text", 
          text: `Found ${locations.length} location(s):\n\n${formattedLocations}` 
        }]
      };
    }
  );

• src/index.js:51-73 (handler)

  The handler function for the searchLocation tool. It calls the helper to search locations and formats the response as text.

  async ({ locationName }) => {
    const locations = await searchLocation(locationName);
    
    if (locations.length === 0) {
      return {
        content: [{ 
          type: "text", 
          text: `No locations found for "${locationName}".` 
        }]
      };
    }
  
    const formattedLocations = locations.map(loc => 
      `${loc.name}${loc.plz ? ` (${loc.plz})` : ''}, ${loc.land} - ID: ${loc.id}`
    ).join('\n');
  
    return {
      content: [{ 
        type: "text", 
        text: `Found ${locations.length} location(s):\n\n${formattedLocations}` 
      }]
    };
  }

• src/index.js:50-50 (schema)

  Input schema for the searchLocation tool using Zod, defining locationName as a string.

  { locationName: z.string().describe("The name of the location to search for") },

• src/index.js:20-30 (helper)

  Helper function that performs the API call to search for locations by name.

  // Helper function to search for locations
  async function searchLocation(locationName) {
    try {
      const response = await axios.get(`https://www.landi.ch/weather/api/geosuche/de/${encodeURIComponent(locationName)}`);
      console.error('Search Location API Response:', JSON.stringify(response.data, null, 2));
      return response.data.orte || [];
    } catch (error) {
      console.error("Error searching for location:", error.message);
      return [];
    }
  }
