## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-07.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 61/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 705 tokens (~141/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 98/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 93% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### `generate_qr` (~274 tokens)

Generate QR code

Generate a scannable QR code (PNG or SVG) for a URL, plain text, Wi-Fi login, contact card (vCard), SMS, WhatsApp, map location, or calendar event. Every result is decode-verified server-side before it is returned. Free, no API key. Powered by HonestQR (https://qr.zalize.com).

Input parameters:

- `bg` (string): Background hex color, default #ffffff
- `data` (string): Payload for type url (the link) or text (free text)
- `ecLevel` (string): Error correction level
- `event` (object): Calendar event fields (type event)
- `fg` (string): Foreground hex color, default #0f172a
- `format` (string)
- `geo` (object): Coordinates (type geo)
- `size` (integer): Approximate PNG size in px
- `sms` (object): SMS fields (type sms)
- `theme` (string): Theme id from list_themes (colors + optional gradient). Overrides fg/bg.

- `wifi` (object): Wi-Fi credentials (type wifi)

### `generate_pixel_art_qr` (~301 tokens)

Generate pixel-art QR code

Generate an artistic QR code with pixel art embedded via a halftone technique: pixel text (up to 8 Latin characters/digits) or one of the built-in pixel icons, plus optional gradient color themes. The QR stays fully scannable (error correction H + server-side decode verification). Use list_icons and list_themes to see available options.

Input parameters:

- `data` (string): Payload for type url (the link) or text (free text)
- `event` (object): Calendar event fields (type event)
- `fg` (string): Foreground hex color, default #0f172a
- `format` (string)
- `geo` (object): Coordinates (type geo)
- `icon` (string): Pixel icon id from list_icons (used when text is not given)
- `size` (integer): Approximate PNG size in px
- `sms` (object): SMS fields (type sms)
- `text` (string): Pixel text to embed (A-Z, 0-9, basic punctuation)
- `theme` (string): Theme id from list_themes. Overrides fg/bg.
- `type` (string, required): QR content type
- `vcard` (object): Contact card fields (type vcard)
- `whatsapp` (object): WhatsApp fields (type whatsapp)
- `wifi` (object): Wi-Fi credentials (type wifi)

### `decode_qr` (~66 tokens)

Decode QR code

Decode a QR code from a PNG image (base64). Returns the raw payload and its detected content type (url, wifi, vcard, sms, geo, event, ...).

Input parameters:

- `image_base64` (string, required): Base64-encoded PNG image (data URI prefix allowed)

### `list_themes` (~30 tokens)

List QR color themes

List the available color themes (solid and gradient) for generate_qr and generate_pixel_art_qr.

### `list_icons` (~34 tokens)

List pixel icons

List the built-in pixel icon ids for generate_pixel_art_qr, with an ASCII preview of each 16x16 icon.
