## Exfil surface

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__crime-data__postcode_summary` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Changes things (4)

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

### `area_rankings`

- 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
Postcode districts in England and Wales ranked by published street-crime records,
    anti-social behaviour included, per 1,000 Census 2021 residents. Each row has the rate, the
    counts behind it, and its page_url. These are published rates, not safety ratings.
```

### `area_summary`

- 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
Published street-crime figures for a UK postcode district.

    Given a postcode, answers for its whole postcode district (E8 for E8 1AA), never for the
    exact postcode. Returns the district's last 12 published months: total, monthly series,
    categories, and the covering police force, with page_url, a citation, and the attribution.
    For a full postcode that is not known to be outside England and Wales, the result also has
    free_report_url, the free result page for the 0.5 km around it.
    
```

### `methodology`

- 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
Notes on how CrimeMapsUK builds its figures: coverage, approximate locations, postcode
    assignment, rates, rankings, outcomes, and how to cite a page, with the methodology
    page_url.
```

### `postcode_summary`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Published street-crime records in the fixed 0.5 km circle around a postcode, over the 12
    months up to the latest published month: the total, the month window, the coverage state,
    and the largest category, with page_url, a citation, and free_report_url. Called with a
    CrimeMapsUK API key, it returns every category's count. The free figures come from a snapshot
    up to six hours old and keyed ones from one up to 15 minutes old, so they can differ briefly
    after new data is published.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `crime-data`:

    "allow": [],
    "ask": [
      "mcp__crime-data__area_summary",
      "mcp__crime-data__area_rankings",
      "mcp__crime-data__methodology",
      "mcp__crime-data__postcode_summary"
    ],
    "deny": []
  }
}
```

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