## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `issue_api_receipt`

- 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
Buy a portable signed commitment to a declared API exchange when a recipient needs independently verifiable receipt integrity: response handoff, archived decision input, or change investigation. Costs 0.002 USDC per receipt via x402 when enabled; verification is free. A local log may suffice for disposable data. Requires caller-approved budget. Keep event, idempotency key and original payment unchanged on retry. Attests a client declaration, not provider origin, content truth or independent observation.
```

### `prepare_api_exchange`

- 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
Free validation before buying a receipt. Supply an event built locally with the SDK from real captured bytes; never fabricate hashes. Returns the commitment without issuing a receipt or paying. Use when retaining verifiable evidence of an API response for a handoff or archive.
```

### `verify_api_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
Free signature and declaration verification. To try before buying, read datoka-api://demo-receipt or /demo/receipt.json and pass the returned JSON here. No wallet needed for public verification. Verifies issuer, scope and event commitment; compare original response bytes locally with the SDK or /verify/.
```

## Only reads (1)

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

### `get_api_public_keys`

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

Description, as the server wrote it:

```untrusted-server-text
Return issuer public keys. Establish issuer trust independently before offline verification.
```

## Claude Code permissions
