## 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 2026-10-23.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - 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**: 69/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1207 tokens (~402/item across 3 items; 2 tools + 1 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**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.
  - Supports UI / widget rendering.

### `generate_qr_code` (~840 tokens)

Generate QR code

Use this when the user wants a QR code: for a website link, plain text, an email, a phone number, an SMS, a contact card (vCard), or a calendar event. Returns the code as SVG with PNG and SVG download links, plus scan warnings (low contrast, high density) and an optional minimum print size. Plain text and SMS text are limited to 1,500 characters; URLs to 2,000; encoded content must fit the QR byte capacity (1,273–2,953 bytes depending on error correction). Generates static codes only; it does not shorten links, track scans, or make Wi-Fi codes. Do not use for barcodes (EAN/UPC/Code 128).

Input parameters:

- `background` (string): Background colour as hex, e.g. #FFFFFF (default).
- `body` (string): For kind=email: prefilled body, e.g. Hi, I would like to book a table for 4.
- `email` (string): For kind=email: recipient address, e.g. hello@example.com. For kind=contact: the contact's email.
- `end` (string): For kind=event: end as local date-time YYYY-MM-DDTHH:MM, e.g. 2026-11-05T21:00. For an all-day event, the last day YYYY-MM-DD (inclusive).
- `error_correction` (string): Damage tolerance, e.g. M: L 7%, M 15% (default), Q 25%, H 30%. Use H for printed codes that may get scuffed or carry a logo sticker.
- `foreground` (string): Code (module) colour as hex, e.g. #111111 (default). Dark colours scan best. Basic colour names like navy or black also work.
- `kind` (string, required): What the code should do when scanned: url (open a website), text (show plain text), email (compose an email), phone (call a number), sms (start a text message), contact (save a vCard contact), event…
- `location` (string): For kind=event: venue or address text shown in the calendar entry, e.g. Pier 39, San Francisco.
- `name` (string): For kind=contact: full name, e.g. Jane Doe. For kind=event: event title, e.g. Launch party.
- `organization` (string): For kind=contact: company or organization, e.g. Acme Inc.
- `phone` (string): For kind=phone, sms, or contact: phone number, ideally in international format, e.g. +1 415 555 0100. Letters (1-800-FLOWERS) are converted to keypad digits; an extension such as "ext. 23" is dialled…
- `scan_distance_cm` (number): Optional distance in centimetres from which people will scan the printed code, e.g. 300 for a poster across a room; used to recommend a minimum print size.
- `start` (string): For kind=event: start as local date-time YYYY-MM-DDTHH:MM, e.g. 2026-11-05T18:30, or a date YYYY-MM-DD for an all-day event. Times are local to the phone that scans the code.
- `subject` (string): For kind=email: subject line, e.g. Table booking.
- `text` (string): For kind=text: the text to encode, e.g. Table 12 - ask for the specials. For kind=sms: the prefilled message, e.g. JOIN.
- `title` (string): For kind=contact: job title, e.g. Head of Sales.
- `url` (string): For kind=url: the http or https web address, e.g. https://example.com/menu. https:// is added if missing.
- `website` (string): For kind=contact: website URL, e.g. https://example.com.

Output parameters:

- `background` (string)
- `contrast_ratio` (number)

Input parameters:

- `background` (string): Background colour as hex, e.g. #FFFFFF (default).
