Trust breakdown (6 categories)

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. How we score →

Endpoint Security63

The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
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. See how to fix → View diagnostics → Unverified
HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail

Transport & Reachability100

Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass

Schema Quality & AI Usability85

100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
AI-judged instruction clarity (good).Pass
Tool/resource definitions use about 1250 tokens (~56/item across 22 items; 17 tools + 5 resources), lean.Pass
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management3

Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Coverage96

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
87% of tool parameters carry a description.Partial

Capabilities100

Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Tool Tokens

bulk_create_dynamic_qr ~57

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

Input Output Examples

Name	Type	Req	Description
codes	array	yes	Codes to create.
theme	string	–	A saved theme id or name applied to every code created.

No output schema declared.

No examples provided.

clear_subdomain ~52

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.

Input Output Examples

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

create_dynamic_qr ~79

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

Input Output Examples

Name	Type	Req	Description
destination	string	yes	The http(s) URL the code should point to.
label	string	–	Optional label.

name	string	yes	–

No output schema declared.

No examples provided.

create_theme ~77

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

Input Output Examples

Name	Type	Req	Description
name	string	yes	–
style	object	yes	QR style JSON (colours, dot/corner shapes, logo, gradient, frame…).

No output schema declared.

No examples provided.

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

Input Output Examples

Name	Type	Req	Description
id	string	yes	The dynamic code id.

No output schema declared.

No examples provided.

delete_folder ~36

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

Input Output Examples

Name	Type	Req	Description
id	string	yes	–

No output schema declared.

No examples provided.

delete_theme ~36

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

Input Output Examples

Name	Type	Req	Description
id	string	yes	–

No output schema declared.

No examples provided.

generate_qr ~110

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

Input Output Examples

Name	Type	Req	Description
data	string	yes	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.

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 Output Examples

Name	Type	Req	Description
id	string	yes	The code id.

No output schema declared.

No examples provided.

id	string	yes	The dynamic code id.

No output schema declared.

No examples provided.

get_subdomain ~61

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.

Input Output Examples

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

list_dynamic_qr ~57

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

Input Output Examples

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

set_subdomain ~84

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.

Name	Type	Req	Description
subdomain	string	yes	3–32 letters, numbers or hyphens, e.g. "acme".

No output schema declared.

No examples provided.

folder_id	string\|null	–	Move into a folder id, or null to un-file.
id	string	yes	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.

No output schema declared.
