**4 tools: 3 change things and 1 only read.**

| Group | Class | Tools | Claude Code |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## 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 `barcode_generate` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "barcode_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 "barcode_generate" says "generate": a word for a change.
```


## Changes things (3)

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

### `barcode_generate`

- The name "barcode_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
Code 128, EAN-13, UPC-A or EAN-8 as SVG/PNG/data URL. EAN/UPC: pass digits without check digit to have it added, or with it to verify. Static codes only: no redirects, no dynamic/editable codes, no scan analytics. EAN/UPC output is format-valid (check digit) and is NOT GS1 registration. Scannability is not guaranteed (contrast, print size, quiet zone and reader all matter).
```

### `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 static QR code as SVG (default, up to 2000 px), PNG base64 or data URL (up to 1024 px) from data or a payload object. Bulk (/v1/qr/bulk, ≤50) is SVG-only, ≤256 bytes per item. Static codes only: no redirects, no dynamic/editable codes, no scan analytics. EAN/UPC output is format-valid (check digit) and is NOT GS1 registration. Scannability is not guaranteed (contrast, print size, quiet zone and reader all matter).
```

### `qr_payload_build`

- 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
Build and validate a QR payload string for type text/url/wifi/vcard/mailto/tel/sms/geo (e.g. {"type":"wifi","ssid":"Cafe","password":"..."}). Returns the string only.
```

## Only reads (1)

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

### `qr_inspect`

- The name "qr_inspect" says "inspect": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return QR version, ECC, module count, capacity used % and quiet-zone/density warnings for data. No image.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `qrmint`:

```json
{
  "permissions": {
    "allow": [
      "mcp__qrmint__qr_inspect"
    ],
    "ask": [
      "mcp__qrmint__qr_generate",
      "mcp__qrmint__barcode_generate",
      "mcp__qrmint__qr_payload_build"
    ],
    "deny": []
  }
}
```
