qart.uk QR studio is a remote MCP server that gives an AI agent 8 tools, among them browse_free_pool, buy_qr_outright, explain_qart. It answers at https://qart.uk/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 12 September 2026; the last check, on 24 October 2026, succeeded.
qart.uk MCP server: resolve scanned codes, browse the free pool, and buy QR artwork.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
browse_free_pool | List the QR artwork currently claimable for free on qart.uk, one per style, with a preview image URL for each. This is the ANONYMOUS shelf — the same selection every signed-out visitor sees, and these codes are what a guest can claim. Use i |
buy_qr_outright | How to buy ONE finished QR artwork with no account at all, paying from your own wallet over x402. Returns the live price and the exact request to make. This is the right tool when you have a wallet but no qart.uk account: get_credit_packs b Inputs: url, size |
explain_qart | Explain how qart.uk works: scan verification, retargeting a printed code, the free claim pool and its daily allowances, Studio pricing, and what happens to credits when a run is stopped or fails. Use this before guessing at product details Inputs: topic |
get_credit_packs | What Studio credits cost: the packs on sale, their price in USD, and roughly how many images each buys. Anonymous — this is a price list. Read it rather than quoting a price from memory; packs change. An agent that runs out mid-task can top |
get_dither_qr_parameters | The complete parameter contract for qart.uk's dithered photo QR recipe — an error-diffused technique (after andrew-t) that dithers a photograph into the space around each QR module, so the finished 1-bit image reads as a picture and still s |
get_qr_matrix | Return the actual QR MODULE GRID for a payload — the black/white matrix, plus a per-module map of which modules are function patterns (finder, separator, timing, alignment, format info, version info, dark module) and which carry data. Both Inputs: payloadKind, url, text, ssid, password, auth |
preview_qr_encoding | Work out how a payload will encode as a QR code, without creating anything. Returns the exact string the pixels would carry, its byte length, the QR version and module count required, the capacity remaining at that version, and any warnings Inputs: payloadKind, fields, url, text, ssid, password |
resolve_qart_code | Resolve a scanned qart.uk code to the URL it currently points at. Accepts the alias ('_ab12cde'), or a full qart.uk URL to pull it out of. Returns targetUrl, or disabledReason if the owner retired it. This does not count as a scan and will Inputs: code |

Yes. It is published by qart.uk and served from qart.uk, the vendor's own domain: https://qart.uk/api/mcp.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://qart.uk/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
