## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `issue_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
Mint a verifiable provenance receipt for an autonomous-agent action. Returns a signed (ed25519), content-hashed (SHA-256), server-timestamped receipt that is hash-chained to this agent's prior receipts (tamper-evident audit trail). Pass the raw inputs/outputs (we hash them — raw data is never stored) OR pre-computed sha256 hashes. Use for compliance, audit trails, and dispute resolution of agentic actions. PAID: $0.01 USDC/call via x402.
```

### `verify_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
Verify a receipt by id (or by passing the full receipt object). Recomputes the content hash, confirms the id commits to the body, and checks the ed25519 signature. Returns the verification checks plus the provenance record (action, agent, input/output hashes, timestamp, chain position). FREE.
```

## Only reads (1)

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

### `list_receipts`

- The name "list_receipts" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the receipt hash-chain for an agent_id, newest first (id, action, timestamp, sequence, hashes, verifyUrl). Use to audit everything a given agent has attested. FREE.
```
