No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_certificate`

- 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
Connects to a domain on port 443 and reports its TLS certificate: whether it is trusted and matches the name, the issuer, the expiry date and days left, the lifetime, the chain and the TLS version.
```

### `check_domain_expiry`

- 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
Looks up when a domain registration expires, over RDAP at the registry for its TLD. Subdomains are looked up by their registered domain (www.example.co.uk becomes example.co.uk).
```
