## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `book_stay`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Holds the home and returns a secure Stripe payment link. The booking is confirmed only when the guest pays on that page. Ask the guest for their full name and email first.
```

## Only reads (1)

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

### `search_stays`

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

Description, as the server wrote it:

```untrusted-server-text
Private homes in Vancouver, Burnaby and West Vancouver, BC that are free for the dates, with the exact total (cleaning and 5% GST included, no service fee). Show each home's link; the guest can book on the page or ask you to book.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `stays`:

    "allow": [
      "mcp__stays__search_stays"
    ],
    "ask": [
      "mcp__stays__book_stay"
    ],
    "deny": []
  }
}
```
