Available components
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 → Why this is hard to 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 6 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 Usability70
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1233 tokens (~205/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "quality_qr_delete" implies "delete" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities40
- Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28. See how to fix → Fail
How do I install the Quality QR MCP server?
Quality QR is a hosted endpoint at https://quality-qr.app/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
quality_qr_analytics ~157
Get scan analytics for a specific QR code. Use this when the user wants to know how many times a QR code has been scanned, see daily scan trends, understand which devices are scanning, or see which countries scans come from.

No output schema declared.
No examples provided.
quality_qr_create ~565
Create a new trackable QR code saved to your Quality QR account. Use this when the user wants to generate a QR code for a URL, WiFi network, contact card, calendar event, phone number, email, SMS, restaurant menu, app download link, or social media profile. The QR code is persisted with scan tracking and analytics. Returns an inline SVG image of the QR code.
| Name | Type | Req | Description |

| design | object | – | Optional visual customization for the QR code. |
| isDynamic | boolean | – | Set to true to create a dynamic QR code whose destination URL can be changed later without reprinting the physical code. Only works for URL-based types (url, pdf, menu, app-store, social). Default: f… |
| name | string | – | A human-readable name for the QR code, e.g. 'Office WiFi' or 'Spring Menu 2026'. Auto-generated as 'MCP: {type} {date}' if omitted. |
| type | string | yes | QR code content type. 'url' for websites, 'wifi' for network credentials, 'vcard' for contact cards, 'email' for pre-filled emails, 'phone' for tap-to-call, 'sms' for pre-filled texts, 'text' for pla… |

| Name | Type | Req | Description |
|---|---|---|---|
| destinationUrl | string | – | New destination URL. Only works for dynamic URL-based types (url, pdf, menu, app-store, social). The physical QR code does not need reprinting. |

What is the Quality QR MCP server?
Quality QR is an MCP server listed in the public MCP registry as io.github.silly-geese/quality-qr. Create and manage trackable QR codes with scan tracking, analytics, and dynamic URL updates. This page covers its hosted endpoint (https://quality-qr.app/api/mcp).
Is the Quality QR MCP server safe to use?
Quality QR scores 76 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Quality QR MCP server expose?
Quality QR exposes 6 tools: quality_qr_create, quality_qr_list, quality_qr_get, quality_qr_update, quality_qr_delete, quality_qr_analytics. Their descriptions and schemas cost roughly 1,233 tokens of context every time the server is loaded.
Does the Quality QR MCP server require authentication?
No. We connected to Quality QR without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Quality QR MCP server still maintained?
Quality QR is still listed as active in the MCP registry. We last reached this channel on 25 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
