| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__anchorages__list_regions` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

### `find_anchorages`

- The name "find_anchorages" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Lists the places near a position where boats stopped, overnight or by day, with where boats stayed in tonight's forecast there or in a given wind. For tonight, call it without wind_from and wind_kn: the answer then carries tonight's forecast at the position and each place's nights in each of tonight's winds, as the site's Tonight does. Give a wind only to ask about that wind. Each place comes with how far and which way it lies from the position (e.g. 0.5 NM SW), its nights, where it is, its page and its place on the map. With a wind, each place gets its nights in that wind, split by strength, with the gusts on those nights (kt), and the list is sorted by those nights. A wind is counted as the site counts it: its compass point at 10 or 20 kt or more, as the forecast's band (e.g. wind_kn 15 counts E 10 kt or more). wind_from alone counts the direction at any strength. A night counts once, in the wind it blew from most. Tonight is counted as the site's Tonight counts it: tonight's forecast times that are night there, each counted in its compass point at 10 or 20 kt or more, as its band, and each place's fewest nights in any one of them. Places with a night in every one of tonight's winds come first, by those fewest nights, then the rest. Without a forecast, by distance. Positions are WGS84 decimal degrees.
```

### `get_bay_evidence`

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

Description, as the server wrote it:

```untrusted-server-text
What boats did at one place, as its page on the site shows it. Its nights. Its nights by the eight compass points the wind blew from, split under 10, 10 to 20 and 20 kt or more, with the different boats and the windiest night of each. Its boats by length and type (cells under 3 boats null), its day stops by wind, its nights by swell direction where its page shows them, and the places nearby with how far and which way. It carries tonight's forecast at the place: the night's strongest forecast wind and the place's nights in that wind, as its page's Tonight shows it. Give bay_id, or name with near (WGS84 decimal degrees) to rank places of one name. Several places of one name come back as candidates.
```

### `get_climatology`

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

Description, as the server wrote it:

```untrusted-server-text
Wind through the year at a place, as its page shows it: for each month, the nights whose strongest hour reached 20 kt and 30 kt, each year's fewest and most of them, the commonest directions of the nights of 20 kt or more, and the strongest gust, over ten years, for the area round the place. The first call for an area can answer preparing, then ready a few minutes later.
```

### `list_regions`

- The name "list_regions" says "list": a word for reading.
- Tag private-data: The description's first sentence says "directory": it reads files.

Description, as the server wrote it:

```untrusted-server-text
The site's directory of places where boats stayed the night. Without a country: each country with its number of places. With a country (directory slug or ISO code): its regions and cruising areas with their number of places. Each with the address of its directory page.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `anchorages`:

```json
{
  "permissions": {
    "allow": [
      "mcp__anchorages__find_anchorages",
      "mcp__anchorages__get_bay_evidence",
      "mcp__anchorages__get_climatology",
      "mcp__anchorages__list_regions"
    ],
    "ask": [],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__anchorages__list_regions`: private-data
