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

### `check_lookalike_domains`

- The description's first verb is "find": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "find" and "website": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Find lookalike domains of a brand's website: typos, swapped letters, look-alike characters, added words and other TLDs. Checks which of them resolve in DNS and what their front page shows (a page using the brand's name, a redirect to the brand's own site, another live site, or nothing). Read-only. Same check as https://openbait.com/tools/typosquat-check.
```
