## Exfil surface

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

| 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__maps-public__get_public_map` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__maps-public__get_public_map` |

## Findings

No check matched anything in these tool definitions.


## Only reads (2)

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

### `get_public_map`

- The name "get_public_map" says "get": a word for reading.
- Tag untrusted-input: The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
One published map as Markdown: description and sources, the timeline of keyframes (date and caption), layers, events, and the iframe code to embed the interactive map. Pass its URL, or the handle and slug.
```

### `search_maps`

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

Description, as the server wrote it:

```untrusted-server-text
Find published animated maps on Moving Polygons (history, wars, empires, borders, epidemics, sea ice…) by words in their title or description and/or a year they cover. Returns links to the interactive map, its text version and its article.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__maps-public__search_maps"
    ],
    "ask": [
      "mcp__maps-public__get_public_map"
    ],
    "deny": []
  }
}
```

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

- `mcp__maps-public__get_public_map`: untrusted-input, outbound
