QR codes in Cursor — MCP setup
Add UseQR to the Cursor MCP config and the agent can make verified QR codes. It is free forever, there is no account, and there is no API key to request.
Setup
~/.cursor/mcp.json
{
"mcpServers": {
"useqr": {
"url": "https://useqr.app/api/mcp"
}
}
}Or call it directly from code
const png = await fetch("https://useqr.app/q/hello.png").then((r) => r.arrayBuffer());What you should know
- No API key to store in your dotfiles, and nothing to rotate.
- The verify tool rasterises the styled output and reads it back with a real decoder, so the agent can prove a branded code still scans before committing it.
