## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `get_port`

- The name "get_port" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
A port's Arrivals board (ships in port now, then ships en route by ETA) and Departures board (ships that left in the last 48 hours), as its Shiptrail page shows them, by UN/LOCODE. Each row carries the ship's MMSI for get_ship.
```

### `get_ship`

- The name "get_ship" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Everything Shiptrail's page shows about one ship, by MMSI: identity, size, position, speed, course and status, destination and ETA, where she came from, recent port calls, particulars and registry facts, photo and its credit, a Wikipedia summary, and the ships near her. No history over time.
```

### `search_ports`

- The name "search_ports" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find ports by name or UN/LOCODE. Busy ports come first, with how many ships are in port, en route and lately departed. Use get_port with a UN/LOCODE for its boards.
```

### `search_ships`

- The name "search_ships" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find ships by name, MMSI (9 digits) or IMO number (7 digits): every ship with a Shiptrail page, any class, on the map now or heard in the last year. Ships on the map now come first. Use get_ship with an MMSI for the whole record.
```
