No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

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

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_suitability`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Rule-based suitability for one plate. Returns status, reasons, verification, sources, and the canonical URL. Does not recommend a centre.
```

## Only reads (5)

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

### `get_atlas_overview`

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

Description, as the server wrote it:

```untrusted-server-text
Country and area coverage with a verification breakdown and hub URLs.
```

### `get_latest_conditions`

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

Description, as the server wrote it:

```untrusted-server-text
Timestamped condition reports for a plate. Diver names, emails, and user IDs are omitted. Includes verification.
```

### `get_site_plate`

- The name "get_site_plate" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Full plate for a slug, including verification, sources, and the canonical URL.
```

### `list_centres`

- The name "list_centres" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Public centre fields already shown on centre pages. No phone, email, or ranking.
```

### `search_sites`

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

Description, as the server wrote it:

```untrusted-server-text
Search dive-site summaries. Each item includes a verification tier and a canonical URL for citation.
```
