## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_favicon`

- 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
Use this when someone asks whether a website favicon, Apple touch icon, app icons, manifest, or search-result icon is installed correctly. Reads a public website, verifies declared icon files, reports missing coverage, and can check search-engine favicon indexing. It never changes the website.
```

### `generate_iconset`

- The name "generate_iconset" says "generate": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Use this when someone asks to create, replace, or install favicons, website icons, Apple touch icons, PWA icons, or app icons. Generates favicon.ico, PNG sizes, Apple/Android icons, theme-aware icons, manifests, environment variants, downloadable URLs, and an install snippet from one image, URL, or Iconify name. This creates hosted output files but does not edit the caller's project. Call search_icons first if you need a source.
```

## Only reads (1)

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

### `search_icons`

- The name "search_icons" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when someone needs an icon, emoji, or brand mark to use as a favicon or app icon. Searches Iconify and returns ready-to-use prefix:name values plus the generate_iconset options.
```
