## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `book_delivery`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Book a same-day courier delivery on a Comet account. Call first without confirm to get a preview (price, vehicle, pickup time); show it to your user; then call again with the same details and confirm=true to place the order. Returns the Comet order number. Needs the client's Comet account key (Authorization: Bearer cmt_...). Account holders get one from Comet at (312) 786-2288.
```

### `recent_orders`

- 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.

Description, as the server wrote it:

```untrusted-server-text
The account's latest orders with their status. Needs the client's Comet account key (Authorization: Bearer cmt_...). Account holders get one from Comet at (312) 786-2288.
```

## Only reads (2)

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

### `get_quote`

- The name "get_quote" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Price a same-day courier delivery in the Chicago area with Comet Messenger Service (since 1976). Returns live prices for Streak (fastest), Priority and Standard service, and the vehicle used. Quotes only - nothing is booked. Account holders' agents can book with book_delivery; everyone else books by calling (312) 786-2288 or at https://cometmessenger.delivery.
```

### `order_status`

- The name "order_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Where an order on the account is: booked, picked up, delivered (with who signed and when) or cancelled. Needs the client's Comet account key (Authorization: Bearer cmt_...). Account holders get one from Comet at (312) 786-2288.
```
