## 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 2026-08-19.

- **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 17 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**: 85/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1250 tokens (~56/item across 22 items; 17 tools + 5 resources), lean.
  - 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**: 96/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 87% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

First indexed and scored.

## MCP tools (17)

### `generate_qr` (~110 tokens)

Generate a static QR code from any text/URL. Returns a PNG image (or SVG markup). Requires an OpenQR API key.

Input parameters:

- `data` (string, required): The content to encode (URL or text).
- `format` (string): Output format (default png).
- `size` (number): Pixel size, 64–2048 (default 512).
- `theme` (string): A saved theme id or name. Applies the theme's colours (SVG); full styling applies to dynamic codes.

### `create_dynamic_qr` (~79 tokens)

Create an editable (dynamic) QR code whose destination you can change later without reprinting. Requires an OpenQR API key.

Input parameters:

- `destination` (string, required): The http(s) URL the code should point to.
- `label` (string): Optional label.
- `theme` (string): A saved theme id or name to style the code with.

### `update_dynamic_qr` (~291 tokens)

Edit a dynamic QR code: change its destination, label, custom short link (slug), tags or folder. Pass only the fields you want to change. Requires an OpenQR API key.

Input parameters:

- `destination` (string): New http(s) URL.
- `folder_id` (string|null): Move into a folder id, or null to un-file.
- `id` (string, required): The dynamic code id.
- `label` (string): New label.
- `lock_hint` (string|null): Optional hint shown on the unlock page, e.g. "Ask at the bar". Max 60 characters.
- `password` (string|null): Pro: require this password before the code redirects (min 4 characters). Pass null to remove all protection.
- `pin` (string|null): Pro: require a 4-digit PIN before the code redirects. Exactly 4 digits. Pass null to remove all protection.
- `slug` (string): Custom short-link back-half (oqr.to/<slug>): 3–48 letters, numbers or hyphens.
- `status` (string): Pause the code (it stops resolving — scanners see an inactive page) or reactivate it. Free plan allows up to 3 active codes.
- `tags` (array): Replace the code's tags (max 10).
- `theme` (string): A saved theme id or name to restyle the code with.

### `get_dynamic_qr` (~58 tokens)

Get the full details of one of your QR codes by id: destination, short link, label, type, tags, folder, status and created date. Requires an OpenQR API key.

Input parameters:

- `id` (string, required): The code id.

### `get_scans` (~36 tokens)

Get scan statistics for a dynamic QR code. Requires an OpenQR API key.

Input parameters:

- `id` (string, required): The dynamic code id.

### `list_dynamic_qr` (~57 tokens)

List your dynamic (editable) QR codes — id, short URL, destination, label and status. Requires an OpenQR API key.

Input parameters:

- `limit` (number): Max codes to return, 1–500 (default 200).

### `delete_dynamic_qr` (~42 tokens)

Permanently delete a dynamic QR code. The short link stops working. Requires an OpenQR API key.

Input parameters:

- `id` (string, required): The dynamic code id.

### `bulk_create_dynamic_qr` (~57 tokens)

Create up to 200 dynamic QR codes at once. Requires an OpenQR API key.

Input parameters:

- `codes` (array, required): Codes to create.
- `theme` (string): A saved theme id or name applied to every code created.

### `list_folders` (~24 tokens)

List your folders (id and name). Requires an OpenQR API key.

### `create_folder` (~29 tokens)

Create a folder to organise codes. Requires an OpenQR API key.

Input parameters:

- `name` (string, required)

### `delete_folder` (~36 tokens)

Delete a folder (its codes are un-filed, not deleted). Requires an OpenQR API key.

Input parameters:

- `id` (string, required)

### `list_themes` (~45 tokens)

List your saved style themes (id, name) — apply one by passing its id or name as `theme` to generate/create/update tools. Requires an OpenQR API key.

### `create_theme` (~77 tokens)

Save a reusable style theme. `style` is a QR style object (fgColor, bgColor, dotType, cornerSquareType, etc.). Requires an OpenQR API key.

Input parameters:

- `name` (string, required)
- `style` (object, required): QR style JSON (colours, dot/corner shapes, logo, gradient, frame…).

### `delete_theme` (~36 tokens)

Delete a saved theme. Codes already styled with it keep their look. Requires an OpenQR API key.

Input parameters:

- `id` (string, required)

### `get_subdomain` (~61 tokens)

Show the branded subdomain on this account ({name}.oqr.to). Reports whether it is currently suspended — a suspended subdomain redirects to the plain short link instead of serving, which happens when a Pro plan lapses. Requires an OpenQR API key.

### `set_subdomain` (~84 tokens)

Claim or change the branded subdomain so codes also resolve at {name}.oqr.to. Pro only. Codes keep working on the plain short link either way, so changing this never breaks anything already printed. Requires an OpenQR API key.

Input parameters:

- `subdomain` (string, required): 3–32 letters, numbers or hyphens, e.g. "acme".

### `clear_subdomain` (~52 tokens)

Release the branded subdomain. Codes stay live on the plain short link; only the {name}.oqr.to form stops resolving. The name becomes claimable by someone else. Requires an OpenQR API key.
