Implementation Reference
- src/index.ts:847-858 (handler)Handler function that takes a Chinese city name, checks if the city exists in the precomputed CITY_STATIONS map, and returns a JSON string of all stations in that city with their names and codes, or an error message if not found.async ({ city }) => { if (!(city in CITY_STATIONS)) { return { content: [{ type: 'text', text: 'Error: City not found. ' }], }; } return { content: [ { type: 'text', text: JSON.stringify(CITY_STATIONS[city]) }, ], }; }
- src/index.ts:844-846 (schema)Zod input schema defining the 'city' parameter as a required string representing the Chinese city name.{ city: z.string().describe('中文城市名称，例如："北京", "上海"'), },
- src/index.ts:841-859 (registration)MCP server.tool registration call that defines the tool name, description, input schema, and handler function.server.tool( 'get-stations-code-in-city', '通过中文城市名查询该城市 **所有** 火车站的名称及其对应的 `station_code`，结果是一个包含多个车站信息的列表。', { city: z.string().describe('中文城市名称，例如："北京", "上海"'), }, async ({ city }) => { if (!(city in CITY_STATIONS)) { return { content: [{ type: 'text', text: 'Error: City not found. ' }], }; } return { content: [ { type: 'text', text: JSON.stringify(CITY_STATIONS[city]) }, ], }; } );
- src/index.ts:48-67 (helper)Precomputed constant mapping Chinese city names to arrays of station objects containing station_code and station_name, built from the global STATIONS data. This is the core data source used by the tool handler.const CITY_STATIONS: Record< string, { station_code: string; station_name: string }[] > = (() => { const result: Record< string, { station_code: string; station_name: string }[] > = {}; for (const station of Object.values(STATIONS)) { const city = station.city; if (!result[city]) { result[city] = []; } result[city].push({ station_code: station.station_code, station_name: station.station_name, }); } return result; })(); //以城市名名为键，位于该城市的的所有Station列表的记录
