## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (5)

Removes, cancels or revokes something. Claude Code: deny.

### `activate_scene`

- The description's first verb is "put": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Put a scene live: every screen and sub-screen in the scene switches at once, in place of what it shows. Running it again puts changes to the scene live. A screen only shows the scene once it is online and has a player paired; each result includes online and paired when the connection may read screens.
```

### `push_content`

- The name "push_content" says "push": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Show content on one screen, or on one sub-screen of a split screen, in place of what it shows now, until a time or until it is put back to normal. A split screen needs a subscreen_id. Returns what the screen shows afterwards. Content only appears once the screen is online and has a player paired; the result includes online and paired when the connection may read screens.
```

### `release_all`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
End all scenes and all pushed content on the team's screens. Screen mirroring keeps running.
```

### `release_scene`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
End one scene: its screens go back to their own content.
```

### `release_screen`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
End pushed content or a scene on one screen or sub-screen; it goes back to its own content.
```

## Changes things (2)

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

### `check_device`

- 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 whether a device (as the user names it, for example "Samsung TV", "Chromecast", "iPad") works with Screenbird. Returns works, coming_soon, does_not_work, works_in_browser or unknown, with an explanation.
```

### `create_design`

- The name "create_design" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a design (a full-screen slide for a screen, such as a menu, an announcement or an event poster) from a description. It picks a fitting template, fills in the text and adds stock photos where the template has them; no images are generated with AI. The design is saved in the team's files and can be shown on a screen or used in a scene. Each design uses the account's AI budget, with at most 20 designs per hour.
```

## Only reads (5)

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

```

### `list_screens`

- The name "list_screens" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
