## Exfil surface

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

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

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__hotels__get_hotel` | `mcp__hotels__check_agent_readiness` | `mcp__hotels__check_agent_readiness` |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `check_agent_readiness`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Scan any hotel or travel website and report how well AI agents can read, price and book it directly: a 0-100 score, what works, and the top fixes.
```

## Only reads (2)

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

### `get_hotel`

- The name "get_hotel" says "get": a word for reading.
- Tag private-data: The description's first sentence says "contact": it reads contacts.

Description, as the server wrote it:

```untrusted-server-text
Full details of one hotel from the Pickrate index by its id (from search_hotels), including policies, contact and a direct-booking link for given dates.
```

### `search_hotels`

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

Description, as the server wrote it:

```untrusted-server-text
Search hotels that can be booked directly (no OTA commission) via Pickrate. Returns name, location, starting rate, amenities, cancellation terms and a direct-booking link. Use it when a traveller asks for a hotel in a city or area. Optionally pass dates and guests to get a booking link that opens live availability.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__hotels__search_hotels",
      "mcp__hotels__get_hotel"
    ],
    "ask": [
      "mcp__hotels__check_agent_readiness"
    ],
    "deny": []
  }
}
```

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

- `mcp__hotels__get_hotel`: private-data
- `mcp__hotels__check_agent_readiness`: untrusted-input, outbound

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:38:17.422Z, unchanged since 2026-10-22T14:38:17.422Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `1` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://pick-rate.com/mcp: tools/list returned 3 tools to an anonymous client, including check_agent_readiness (write)
