## Exfil surface

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

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

### `book_discovery_call`

Description, as the server wrote it:

```untrusted-server-text
Book a real 30-minute Cuvo discovery call for the user. Requires their explicit confirmation of a specific slot from get_availability plus their real full name and email; the calendar invite goes to that email. Do not book without the user's consent.

- The name "request_callback" says "request": a word for a change.

      "mcp__website__list_comparisons",

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.
