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

### `check_site`

- 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
Check a website: does it work, and does it do what it was asked to do? Opens up to 20 pages, tests links, forms and images, compares the brief with the pages, and checks speed and security. Returns a verdict (the literal lowercase word "pass" or "fix"), a score out of 100, sub-scores, the fix list, and the public report URL. One free check per site without a key.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `webcheck`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__webcheck__check_site"
    ],
    "deny": []
  }
}
```
