Implementation Reference
- build/index.js:293-337 (handler)The handleGeo function that executes the maps_geo tool logic: queries Amap geocoding API, parses response to extract location details.async function handleGeo(address, city, sig) { const url = new URL("https://restapi.amap.com/v3/geocode/geo"); url.searchParams.append("key", AMAP_MAPS_API_KEY); url.searchParams.append("address", address); url.searchParams.append("source", "ts_mcp"); const response = await fetch(url.toString()); const data = await response.json(); if (data.status !== "1") { return { content: [{ type: "text", text: `Geocoding failed: ${data.info || data.infocode}`, }], isError: true, }; } const geocodes = data.geocodes || []; const res = geocodes.length > 0 ? geocodes.map((geo) => ({ country: geo.country, province: geo.province, city: geo.city, citycode: geo.citycode, district: geo.district, street: geo.street, number: geo.number, adcode: geo.adcode, location: geo.location, level: geo.level, })) : []; return { content: [{ type: "text", text: JSON.stringify( { return: res, }, null, 2, ), }], isError: false, }; }
- build/index.js:32-50 (schema)Input schema and metadata for the maps_geo tool.const GEO_TOOL = { name: "maps_geo", description: "将详细的结构化地址转换为经纬度坐标。支持对地标性名胜景区、建筑物名称解析为经纬度坐标", inputSchema: { type: "object", properties: { address: { type: "string", description: "待解析的结构化地址信息", }, city: { type: "string", description: "指定查询的城市", }, }, required: ["address"], }, };
- build/index.js:247-260 (registration)maps_geo tool (GEO_TOOL) is registered in the MAPS_TOOLS array returned by ListToolsRequestSchema.const MAPS_TOOLS = [ REGEOCODE_TOOL, GEO_TOOL, IP_LOCATION_TOOL, WEATHER_TOOL, SEARCH_DETAIL_TOOL, BICYCLING_TOOL, WALKING_TOOL, DRIVING_TOOl, TRANSIT_INTEGRATED_TOOL, DISTANCE_TOOL, TEXT_SEARCH_TOOL, AROUND_SEARCH_TOOL, ];
- build/index.js:851-922 (registration)Registration of CallToolRequestSchema handler with switch case dispatching to handleGeo for maps_geo.server.setRequestHandler(CallToolRequestSchema, async (request) => { try { switch (request.params.name) { case "maps_regeocode": { const { location } = request.params.arguments; return await handleReGeocode(location); } case "maps_geo": { const { address, city } = request.params.arguments; return await handleGeo(address, city); } case "maps_ip_location": { const { ip } = request.params.arguments; return await handleIPLocation(ip); } case "maps_weather": { const { city } = request.params.arguments; return await handleWeather(city); } case "maps_search_detail": { const { id } = request.params.arguments; return await handleSearchDetail(id); } case "maps_bicycling": { const { origin, destination } = request.params.arguments; return await handleBicycling(origin, destination); } case "maps_direction_walking": { const { origin, destination } = request.params.arguments; return await handleWalking(origin, destination); } case "maps_direction_driving": { const { origin, destination } = request.params.arguments; return await handleDriving(origin, destination); } case "maps_direction_transit_integrated": { const { origin, destination, city, cityd } = request.params.arguments; return await handleTransitIntegrated(origin, destination, city, cityd); } case "maps_distance": { const { origins, destination, type } = request.params.arguments; return await handleDistance(origins, destination, type); } case "maps_text_search": { const { keywords, city, citylimit } = request.params.arguments; return await handleTextSearch(keywords, city, citylimit); } case "maps_around_search": { const { location, radius, keywords } = request.params.arguments; return await handleAroundSearch(location, radius, keywords); } default: return { content: [{ type: "text", text: `Unknown tool: ${request.params.name}`, }], isError: true, }; } } catch (error) { return { content: [{ type: "text", text: `Error: ${ error instanceof Error ? error.message : String(error) }`, }], isError: true, }; } });
- build/streamable-http.js:57-105 (handler)Identical handler function for maps_geo tool in the HTTP server variant.async function handleGeo(address, city, sig) { const AMAP_MAPS_API_KEY = getApiKey(); const url = new URL("https://restapi.amap.com/v3/geocode/geo"); url.searchParams.append("key", AMAP_MAPS_API_KEY); url.searchParams.append("address", address); url.searchParams.append("source", "ts_mcp"); const response = await fetch(url.toString()); const data = await response.json(); if (data.status !== "1") { return { content: [ { type: "text", text: `Geocoding failed: ${data.info || data.infocode}`, }, ], isError: true, }; } const geocodes = data.geocodes || []; const res = geocodes.length > 0 ? geocodes.map((geo) => ({ country: geo.country, province: geo.province, city: geo.city, citycode: geo.citycode, district: geo.district, street: geo.street, number: geo.number, adcode: geo.adcode, location: geo.location, level: geo.level, })) : []; return { content: [ { type: "text", text: JSON.stringify( { return: res, }, null, 2, ), }, ], isError: false, };
