## Findings

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

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

description: "...er you control. Returns hookId, private credentials and the ownership challenge; delivery r..."
```

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

```untrusted-server-text
The server marks "verify_destination" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The description's first verb is "fetch": a word for reading.
```


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `revoke_destination`

- The name "revoke_destination" says "revoke": a word for removing or ending something.
- The description says "cannot be undone".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Permanently revoke this hook with its management token after explicit owner approval. New submissions are rejected; previously accepted deliveries finish. This does not cancel queued events and cannot be undone. Use get_destination_status first if you only need to inspect access.
```

## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `purchase_hook_credits`

- The name "purchase_hook_credits" says "purchase": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Request an x402 quote without payment, or buy credits with an explicitly authorized signed payment. Reuse purchaseId and the same payment after any timeout.
```

## Changes things (4)

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

### `accept_hook_event`

- 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
Enqueue up to 65536 payload bytes for a previously verified receiver using its delivery token. Returns a deliveryId, not proof of delivery. Reuse eventId and exact bytes on retries, then poll get_hook_delivery. The free allowance is 100 events/day per verified receiver; extra admissions consume purchased credits. No arbitrary destination can be supplied here.
```

### `register_destination`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Register an HTTPS receiver you control. Returns hookId, private credentials and the ownership challenge; delivery remains inactive. Publish the exact challenge on your origin, then call verify_destination. Keep recoveryKey secret and reuse it with the identical target after interruption; do not register again with a new key.
```

### `verify_destination`

- The description's first verb is "fetch": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Fetch the ownership challenge from the previously registered receiver and activate it when valid. First publish the exact challenge returned by register_destination. Requires the management token; does not deliver an event. Use get_destination_status to inspect progress without activation.
```

### `verify_hook_receipt`

- 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
Check an unchanged event and signed receipt returned by get_hook_delivery within the authenticated hook. Requires the delivery token; does not send an event. A valid signature attests relay observations, not business truth or exactly-once processing.
```

## Only reads (3)

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

### `get_destination_status`

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

Description, as the server wrote it:

```untrusted-server-text
Read the existing hook ownership challenge and verification or revocation status using its management token. No activation or delivery. Use after registration or an interrupted verification; use get_hook_delivery for one accepted event.
```

### `get_hook_credits`

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

Description, as the server wrote it:

```untrusted-server-text
Read remaining purchased admission credits for an existing hook using its management token. Free and read-only; does not purchase credits. Use purchase_hook_credits to request a quote. The daily free allowance remains separate.
```

### `get_hook_delivery`

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

Description, as the server wrote it:

```untrusted-server-text
Read one accepted event by its returned deliveryId and hook delivery token. Poll after accept_hook_event to distinguish queued, retried and completed delivery. Signed observations attest relay attempts, not successful business processing by the receiver. No new delivery or payment.
```
