maps_direction_transit_integrated
Plan public transit routes using coordinates and city information to find optimal travel paths across multiple transportation modes including buses, subways, and trains.
Instructions
公交路径规划 API 可以根据用户起终点经纬度坐标规划综合各类公共（火车、公交、地铁）交通方式的通勤方案，并且返回通勤方案的数据，跨城场景下必须传起点城市与终点城市

Implementation Reference
- build/index.js:593-702 (handler)The handler function that executes the core logic: calls Amap API for integrated transit directions (bus, train, subway), handles errors, formats and returns the route data as JSON text content.async function handleTransitIntegrated( origin, destination, city = "", cityd = "", ) { const url = new URL( "https://restapi.amap.com/v3/direction/transit/integrated", ); url.searchParams.append("key", AMAP_MAPS_API_KEY); url.searchParams.append("origin", origin); url.searchParams.append("destination", destination); url.searchParams.append("city", city); url.searchParams.append("cityd", cityd); 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: `Direction Transit Integrated failed: ${ data.info || data.infocode }`, }], isError: true, }; } return { content: [{ type: "text", text: JSON.stringify( { route: { origin: data.route.origin, destination: data.route.destination, distance: data.route.distance, transits: data.route.transits ? data.route.transits.map((transit) => { return { duration: transit.duration, walking_distance: transit.walking_distance, segments: transit.segments ? transit.segments.map((segment) => { return { walking: { origin: segment.walking.origin, destination: segment.walking.destination, distance: segment.walking.distance, duration: segment.walking.duration, steps: segment.walking && segment.walking.steps ? segment.walking.steps.map((step) => { return { instruction: step.instruction, road: step.road, distance: step.distance, action: step.action, assistant_action: step.assistant_action, }; }) : [], }, bus: { buslines: segment.bus && segment.bus.buslines ? segment.bus.buslines.map((busline) => { return { name: busline.name, departure_stop: { name: busline.departure_stop.name, }, arrival_stop: { name: busline.arrival_stop.name, }, distance: busline.distance, duration: busline.duration, via_stops: busline.via_stops ? busline.via_stops.map((via_stop) => { return { name: via_stop.name, }; }) : [], }; }) : [], }, entrance: { name: segment.entrance.name, }, exit: { name: segment.exit.name, }, railway: { name: segment.railway.name, trip: segment.railway.trip, }, }; }) : [], }; }) : [], }, }, null, 2, ), }], isError: false, };
- build/index.js:136-162 (schema)Input schema definition for the tool, including parameters origin, destination, city, cityd with descriptions and requirements.const TRANSIT_INTEGRATED_TOOL = { name: "maps_direction_transit_integrated", description: "公交路径规划 API 可以根据用户起终点经纬度坐标规划综合各类公共（火车、公交、地铁）交通方式的通勤方案，并且返回通勤方案的数据，跨城场景下必须传起点城市与终点城市", inputSchema: { type: "object", properties: { origin: { type: "string", description: "出发点经度，纬度，坐标格式为：经度，纬度", }, destination: { type: "string", description: "目的地经度，纬度，坐标格式为：经度，纬度", }, city: { type: "string", description: "公共交通规划起点城市", }, cityd: { type: "string", description: "公共交通规划终点城市", }, }, required: ["origin", "destination", "city", "cityd"], }, };
- build/index.js:886-889 (registration)Registration in the tool dispatch switch statement within CallToolRequestSchema handler.case "maps_direction_transit_integrated": { const { origin, destination, city, cityd } = request.params.arguments; return await handleTransitIntegrated(origin, destination, city, cityd); }
- build/streamable-http.js:392-508 (handler)Duplicate handler function in the HTTP server version, identical logic calling Amap API for transit directions.async function handleTransitIntegrated( origin, destination, city = "", cityd = "", ) { const AMAP_MAPS_API_KEY = getApiKey(); const url = new URL( "https://restapi.amap.com/v3/direction/transit/integrated", ); url.searchParams.append("key", AMAP_MAPS_API_KEY); url.searchParams.append("origin", origin); url.searchParams.append("destination", destination); url.searchParams.append("city", city); url.searchParams.append("cityd", cityd); 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: `Direction Transit Integrated failed: ${ data.info || data.infocode }`, }, ], isError: true, }; } return { content: [ { type: "text", text: JSON.stringify( { route: { origin: data.route.origin, destination: data.route.destination, distance: data.route.distance, transits: data.route.transits ? data.route.transits.map((transit) => { return { duration: transit.duration, walking_distance: transit.walking_distance, segments: transit.segments ? transit.segments.map((segment) => { return { walking: { origin: segment.walking.origin, destination: segment.walking.destination, distance: segment.walking.distance, duration: segment.walking.duration, steps: segment.walking && segment.walking.steps ? segment.walking.steps.map((step) => { return { instruction: step.instruction, road: step.road, distance: step.distance, action: step.action, assistant_action: step.assistant_action, }; }) : [], }, bus: { buslines: segment.bus && segment.bus.buslines ? segment.bus.buslines.map((busline) => { return { name: busline.name, departure_stop: { name: busline.departure_stop.name, }, arrival_stop: { name: busline.arrival_stop.name, }, distance: busline.distance, duration: busline.duration, via_stops: busline.via_stops ? busline.via_stops.map( (via_stop) => { return { name: via_stop.name, }; }, ) : [], }; }) : [], }, entrance: { name: segment.entrance.name, }, exit: { name: segment.exit.name, }, railway: { name: segment.railway.name, trip: segment.railway.trip, }, }; }) : [], }; }) : [], }, }, null, 2, ), }, ], isError: false, };
