## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `payment_preflight`

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

Description, as the server wrote it:

```untrusted-server-text
Fast pre-payment consistency guard for AI agents. Checks HTTPS destination, EVM payTo format, Base network, amount validity, and detects recipient/network/price changes against caller expectations. Returns allow/review/block. Use vendor_preflight for deep KYB.
```

## Changes things (1)

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

### `vendor_preflight`

- 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 vendor identity before paying: KYB, supplier risk and counterparty checks for AI agents. Returns allow/review/block with legal-entity evidence, potential sanctions signals, RDAP domain evidence and company-domain consistency. Payment safety decision support via x402; not legal or transaction approval.
```
