## Exfil surface

6 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 private-data tool breaks every one: `mcp__cockatoo__onboarding_status`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__cockatoo__onboarding_status` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__cockatoo__preview_site` `mcp__cockatoo__publish_site` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__cockatoo__create_site` `mcp__cockatoo__publish_site` `mcp__cockatoo__start_onboarding` |

## Findings

- **warn** Annotations that disagree with the tool in `catalog` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text

annotations: {"readOnlyHint":true,"openWorldHint":false}; The description's first verb is "start": a word for a change.
```

- **info** The word "credentials" in `onboarding_status` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

description: "...g status using the private continuation credential."
```

- **info** The word "credentials" in `exchange_onboarding` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

description: "...oval, exchange the private continuation credential for an API token. Keep returned credent..."
