## MCP tools (4)

### `subway_route` (~223 tokens)

Subway route

Plan a subway/metro trip in the Seoul Metropolitan Area (Seoul, Incheon, Gyeonggi) between two stations. Accepts station names in English, Korean, Japanese or Chinese, plus common landmarks (Hongdae, COEX, Incheon Airport). Returns lines to take, where to transfer, which direction to board, estimated minutes and fare. Works offline, no API key.

Input parameters:

- `airport_express` (boolean): Allow the AREX direct train (Seoul Station ↔ Incheon Airport), which needs a separate ticket. Default false.
- `allow_express` (boolean): Also consider express trains (Line 9, Line 1, Suin–Bundang…). Default false; express data is less complete.
- `fewer_transfers` (boolean): Prefer fewer transfers even if slightly slower.
- `from` (string, required): Departure station, e.g. 'Myeongdong', '명동', 'Incheon Airport T1'
- `to` (string, required): Arrival station, e.g. 'Seongsu', '성수'

### `subway_station` (~77 tokens)

Find subway station

### `korea_holidays` (~111 tokens)

- `to` (string): End date YYYY-MM-DD. Default: 365 days after start.
