Implementation Reference
- src/index.ts:896-911 (handler)Inline async handler function for the 'get-station-code-by-names' tool. It processes multiple station names separated by '|', optionally strips trailing '站', looks up in NAME_STATIONS map, and returns JSON results or error.
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) }], }; } - src/index.ts:889-895 (schema)Zod input schema defining 'stationNames' parameter as a string supporting multiple names separated by '|'.
