## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `verify_schema`

- 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
Independent acceptance check of AI agent output before paying for another AI agent's work, or before submitting your own: validate an invoice, check its total, or run JSON Schema validation. Checks structure, formats, ranges, and cross-field rules such as 'line totals must equal the total.' Returns pass/fail, % of checks passed, fix hints, and an Ed25519-signed attestation and receipt you can show as evidence of why you paid or refused. $0.02 per check, small next to the payment it protects. Free during launch: 1000 checks a day (MCP and REST).
```

## Only reads (1)

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

### `get_verification_record`

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

Description, as the server wrote it:

```untrusted-server-text
Agent reputation and trust score: use before relying on another AI agent. Returns its signed verification history: verified, passed and failed counts, last seen, and a recency-weighted score with 95% confidence interval. Check a counterparty before you pay, or see the record buyers will see. AI Agent Scores: $0.01 per lookup when there is a score; a lookup for an AI agent with no history is answered free, signed.
```
