Nothing to run from here
QRdx is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Design styled QR codes and build Wi-Fi, contact and SMS payloads. Most tools need no API key.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http qrdx-mcp https://mcp.qrdx.dev/mcp
# 2 — ask your agent for something these tools do
# design_qr, list_options, generate_qr_code and 9 more
QRdx costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http qrdx-mcp https://mcp.qrdx.dev/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
12 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Design a QR code for any content type (link, Wi-Fi, contact, email, SMS, WhatsApp, payments, social profiles and more) with the style you choose: colors and gradients, dot, eye and eye center shapes, a built-in call-to-action frame with its text or a custom frame spec, a border, a logo icon or your own uploaded logo (logo_file_id, with an API key), margin and error correction. Can start from a bui

List every value design_qr accepts: content types with their fields, colors and gradients, body patterns, eye and eye center shapes, frame styles and their text limit, custom frames, border templates, logo icons, built-in presets, error correction levels, margin and size limits, and how the scan score works.
No parameter schema on file.
Render a QR code with the editor's style options: colors or gradients (linear, radial), dot and eye shapes, eye and dot colors, a built-in frame with its text or a custom frame spec, a border template, a logo icon or your own uploaded logo (logoFileId, needs an API key), or a community item.

Save a design to QRdx as a saved theme, listed under Themes in the dashboard and offered in the editor. Needs a QRdx API key with full access on this MCP connection (Authorization: Bearer qrdx_…).

ATool-list grade · score 93 / 100
Release 1.1.0 · scanned 10 Nov 2026
Graded from the tools this server lists, not from its source code.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | moderate | capability blast radius (moderate) — client exposure if the model is manipulated | −3 |
| coverage-honesty | manifest | inspection depth (manifest) — how much of the target the scan could see | −4 |
score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish QRdx can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
