stationNamesYes具体的中文车站名称,例如:"北京南", "上海虹桥"。若要查询多个站点,请用|分割,比如"北京南|上海虹桥"。

Implementation Reference

  • The handler function processes one or more Chinese station names (split by '|'), optionally strips trailing '站', looks them up in the NAME_STATIONS dictionary, and returns a JSON object with station codes or error messages.
    async ({ stationNames }) => {
      let result: Record<string, object> = {};
      for (let stationName of stationNames.split('|')) {
        stationName = stationName.endsWith('站')
          ? stationName.substring(0, -1)
          : stationName;
        if (!(stationName in NAME_STATIONS)) {
          result[stationName] = { error: '未检索到城市。' };
        } else {
          result[stationName] = NAME_STATIONS[stationName];
        }
      }
      return {
        content: [{ type: 'text', text: JSON.stringify(result) }],
      };
    }
  • Zod input schema defining 'stationNames' as a string parameter with description for querying station codes by Chinese names.
    {
      stationNames: z
        .string()
        .describe(
          '具体的中文车站名称,例如:"北京南", "上海虹桥"。若要查询多个站点,请用|分割,比如"北京南|上海虹桥"。'
        ),
    },
  • src/index.ts:634-660 (registration)
    Registers the 'get-station-code-by-names' tool on the MCP server, including name, description, input schema, and handler function.
    server.tool(
      'get-station-code-by-names',
      '通过具体的中文车站名查询其 `station_code` 和车站名。此接口主要用于在用户提供**具体车站名**作为出发地或到达地时,为接口准备 `station_code` 参数。',
      {
        stationNames: z
          .string()
          .describe(
            '具体的中文车站名称,例如:"北京南", "上海虹桥"。若要查询多个站点,请用|分割,比如"北京南|上海虹桥"。'
          ),
      },
      async ({ stationNames }) => {
        let result: Record<string, object> = {};
        for (let stationName of stationNames.split('|')) {
          stationName = stationName.endsWith('站')
            ? stationName.substring(0, -1)
            : stationName;
          if (!(stationName in NAME_STATIONS)) {
            result[stationName] = { error: '未检索到城市。' };
          } else {
            result[stationName] = NAME_STATIONS[stationName];
          }
        }
        return {
          content: [{ type: 'text', text: JSON.stringify(result) }],
        };
      }
    );
