## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "qr_generate" says "generate": a word for a change.
```

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "qr_generate_from_template" says "generate": a word for a change.
```

- **info** The word "credentials" in `qr_build_wifi` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credentials".

description: "Encode Wi-Fi credentials (SSID, password, auth type, hidden flag..."
```


## Changes things (6)

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

### `qr_build_geo`

- 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
Encode a latitude/longitude pair into a geo: URI QR. Scanning opens the location in the device's default maps app.
```

### `qr_build_vcard`

- 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
Encode a contact card (vCard) with first and last name, organization, phone, email and website URL into a QR. Scanning the QR adds the contact to the phone's address book.
```

### `qr_build_wifi`

- 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.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Encode Wi-Fi credentials (SSID, password, auth type, hidden flag) into a scannable Wi-Fi QR. Returns both the WIFI:... payload string and a generated QR image.
```

### `qr_generate`

- The name "qr_generate" says "generate": 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
Generate a fully branded QR code with explicit control over colors, module/finder shapes, logo, caption, and output format. Use this when the user already knows the design they want.
```

### `qr_generate_ai`

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

Description, as the server wrote it:

```untrusted-server-text
Generate a QR code where the QR Branding LLM picks colors and shapes from a natural-language prompt. Best for "make me a luxury gold dotted QR for a coffee brand" style requests.
```

### `qr_generate_from_template`

- The name "qr_generate_from_template" says "generate": 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
Render one of the curated templates by id, optionally overriding the encoded content, colors, or output format/size for this specific call.
```

## Only reads (1)

### `qr_list_templates`

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

Description, as the server wrote it:

```untrusted-server-text
List the 118 pre-designed QR templates (id, name, description, preview thumbnail URL). Filter by category if the user asks for a specific style.
```
