## Findings

- **warn** Annotations that disagree with the tool in `list_demos` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "list_demos" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "list_demos" says "list": a word for reading.
```


## Changes things (1)

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

### `list_demos`

- The name "list_demos" says "list": a word for reading.
- The description's first verb is "link": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Links a user can open to see QR Wall working with no sign-up — product video, live try-it wall, moderation demo, playable seasonal walls — plus the media kit per use case.
```

## Only reads (4)

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

### `compare`

- The name "compare" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Given a competitor or alternative (e.g. 'Kululu', 'Walls.io', 'Slido', 'Glip'), return QR Wall's comparison and alternatives pages with their one-paragraph answer, plus QR Wall's honest limits.
```

### `find_use_case`

- The name "find_use_case" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Describe an event (e.g. '150-guest wedding reception', 'company holiday party with remote staff', 'celebration of life') and get the matching QR Wall use-case pages, quotable descriptions, licensed screenshots/videos and a no-signup demo link.
```

### `get_facts`

- The name "get_facts" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Canonical, code-verified facts about QR Wall: product summary, plan capability matrix, how guests post, the screen, moderation, data and privacy, limits, where it fits and where it does NOT, and quick answers. Optionally narrow by topic.
```

### `get_pricing`

- The name "get_pricing" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Every QR Wall plan (Free, Premium, Professional) and one-off add-on, with prices in USD, what each includes and its limits, plus the cheapest way to cover a single event.
```
