## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `check_domains`

- 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 domain name availability via public registry RDAP for .xyz .com .io .ai .app .dev, plus variations (get-, -hq, -labs, try-). 404 from the registry = likely available. Not a registrar quote; confirm at checkout. PAID via x402: 0.005 USDC on Base per call; call without x_payment to get requirements.
```

## Only reads (1)

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

### `read_url`

- The name "read_url" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch a public web page and return clean Markdown of its main content (title, byline, excerpt, markdown). PAID via x402: 0.005 USDC on Base per successful call. Call without x_payment to get the exact x402 payment requirements; sign them with an x402 client (exact scheme, EIP-3009 USDC transferWithAuthorization) and call again with the base64 PAYMENT-SIGNATURE (v2) or X-PAYMENT (v1) value in x_payment. You are only charged if extraction succeeds.
```
