## 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_vitals`

- 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 a page's real Core Web Vitals: Google's Chrome UX Report field data (real users, 28-day window) plus a live Lighthouse lab run. Returns good/needs-improvement/poor ratings for LCP, INP, and CLS per Google's own published thresholds, and whether the page passes the actual ranking-signal bar. Call this before telling someone a page performs well. Pass a Pro API key as a Bearer token for 500 checks/minute; see /docs for monitoring multiple URLs with daily regression alerts.
```
