## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__tuatara-topics__find_topics` |
| 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 |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `topic_of_document`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Tuatara Topics: place one document on the general topic set (the served model's topics) and return the topics it belongs to with their weights. Nothing is stored.
```

## Only reads (1)

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

### `find_topics`

- The name "find_topics" says "find": a word for reading.
- Tag private-data: The description's first sentence says "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Tuatara Topics: find the topics in a set of documents. Returns num_topics topics, each with its words, a label, a description and a weight, plus every document's topic mixture, in one call; a dictionary model's word knowledge guides a probabilistic topic model, so topics are coherent on small sets and short texts. Nothing is trained on or kept from the request. 4 to 500 documents of up to 20,000 characters per call.
```

## Claude Code permissions

    ],
    "ask": [],
    "deny": [
      "mcp__tuatara-topics__topic_of_document"
    ]
  }
}
```

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

- `mcp__tuatara-topics__find_topics`: private-data
