Qrpaint 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
Art QR codes via a hosted service: generate, vary, list and retarget scannable picture QR codes.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user qrpaint-mcp '--' npx -y @reneturcios/qrpaint mcp
# 2 — ask your agent for something these tools do
# generate_qr_code, generate_qr_code_from_image, vary_qr_code and 6 more
Qrpaint costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts Qrpaint as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.
This is a public server: you run it yourself and this marketplace is not in the path. You need Node.js — the current LTS (24) is the safe choice; npx comes with it. Claude Code registers it in one command; --scope user makes it available in every project. The '--' is in quotes so that PowerShell passes it on.
claude mcp add --scope user qrpaint-mcp '--' npx -y @reneturcios/qrpaint mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
9 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Read from its source code. A server that builds its tool list when it starts can list more tools than this.
Use this when the user wants a new QR code that is also a picture: a scannable code painted into art from a description, that opens a link. It starts the code and answers at once with its id while the picture is painted, which usually takes under a minute; then call get_qr_code with the id to wait…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| prompt | string | yes | What the picture should show, e.g. "a lighthouse on a cliff at sunset". |
| destination | string | yes | The link scans open: an absolute http or https URL, e.g. https://example.com/menu. |
| style | string | no | A style id from list_styles. Leave out for the default. |
Use this when the user wants a scannable QR code woven into a picture they already have (a photo, an illustration or artwork) instead of one painted from a description. Pass the picture once, as exactly one of an attached file (image), a public https link (imageUrl) or base64 (imageBase64): PNG,…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| image | object | no | The picture as a file the user attached in the conversation. |
| imageUrl | string | no | Or: a public https link to the picture. |
| imageBase64 | string | no | Or: the picture as base64, or a base64 data: URL. |
| destination | string | yes | The link scans open: an absolute http or https URL, e.g. https://example.com/menu. |
| prompt | string | no | Optional: what the picture shows, to guide how it is redrawn. Leave out to have it described automatically. |
| style | string | no | A style id from list_styles. Leave out to keep the picture’s own look. |
Use this when the user wants a new QR code based on one of their existing codes, with a change to its picture, e.g. "more trees" or "make it night time". It makes a new code with its own id and short link that opens the same destination and keeps the original’s style and logo; the original code…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | The id of the code to start from. |
| change | string | yes | What to change in the picture, e.g. "add more trees" or "make it autumn". |
Use this when you have a QR code’s id (from generate_qr_code, vary_qr_code or list_qr_codes) and need its status or finished image. While the code is still being painted it waits up to wait seconds (25 by default) for it to finish before answering, so call it again if it is still processing. Do…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | The code’s id. |
| wait | integer | no | Seconds to wait for a processing code to finish before answering, 0 to 25. |
Use this when the user asks about QR codes they already have, newest first, a page at a time (pass nextCursor as cursor for the next page). Do not use it to make a code.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| limit | integer | no | How many codes to return, 1 to 100. |
| cursor | string | no | nextCursor from the previous page. |
Use this when the user wants an existing link QR code to open a different web address. Printed copies follow at once. It only works for link codes, and only if the account’s plan allows changing destinations. Do not use it to make a new code.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | The code’s id. |
| destination | string | yes | The new link scans should open: an absolute http or https URL. |
Use this when the user asks how many QR codes they can still make today, when the daily count resets, or what their QRX account can do. Do not use it to make or list codes.
No parameter schema on file.
Use this when you need to know which QRX account is connected, for example to confirm it with the user. Do not use it for limits; use get_account.
No parameter schema on file.
Use this when the user wants to choose a look for a new QR code; pass a style id to generate_qr_code. Do not use it to make a code.
No parameter schema on file.
- Every tool, no call limit
- No card, and mcprush charges nothing for it
- Source published under MIT
- Runs on your machine — nothing of it reaches our gateway
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable: mcprush charges nothing to install Qrpaint or to call it, at any volume.
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 | minimal | capability blast radius (minimal) — client exposure if the model is manipulated | −0 |
| verification-discount | repo | publisher verification (public source) — no provenance, but the source is public and inspectable | −1 |
| coverage-honesty | source | inspection depth (source) — how much of the target the scan could see | −0 |
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.
Tools were statically extracted from the published source (9 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. minimal is the level these add up to.
| Tool | Capability tags | Why the tag was assigned |
|---|---|---|
| generate_qr_code | no tags | |
| generate_qr_code_from_image | no tags | |
| vary_qr_code | no tags | |
| get_qr_code | no tags | |
| list_qr_codes | no tags | |
| change_qr_code_destination | no tags | |
| get_account | no tags | |
| get_profile | no tags | |
| list_styles | no tags |
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.
Supply chain and provenance
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.
Release history
Always latest — the install command names no version, so it installs the newest release when it runs; the current release on file is 0.1.0. Pin a release below and the command asks for exactly that one.
No release note was published with this version.
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.
Any signed-in account that does not publish Qrpaint can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
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.
