Useqr

useqr-mcp

Generate a static QR code from any AI agent. No account. No API key.

npx -y useqr-mcp generate --data https://example.com --out qr.png

This repository is the agent-facing QR generator for useqr.co. It writes PNG or SVG locally. Styled dots, logos, and dynamic /r/{code} short links stay on the product site.

Install and discovery

• npm: useqr-mcp
• Official MCP registry name: io.github.aaronte/useqr-mcp
• Hosted remote: https://useqr.co/api/mcp
• Search: curl "https://registry.modelcontextprotocol.io/v0.1/servers?search=useqr"

npx -y useqr-mcp

No arguments (or mcp) starts the stdio MCP server. Source install still works: npx -y github:aaronte/useqr-mcp.

MCP

Stdio (works in Cursor, Claude, Copilot, and other clients that spawn a command):

{
  "mcpServers": {
    "useqr": {
      "command": "npx",
      "args": ["-y", "useqr-mcp"]
    }
  }
}

Hosted Streamable HTTP (same tools, nothing to install):

{
  "mcpServers": {
    "useqr": {
      "url": "https://useqr.co/api/mcp"
    }
  }
}

stdio-only clients can wrap the hosted server with mcp-remote:

{
  "mcpServers": {
    "useqr": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://useqr.co/api/mcp"]
    }
  }
}

Tools

CLI

npx -y useqr-mcp generate --data https://example.com --format svg --out qr.svg
npx -y useqr-mcp help

npx -y useqr-mcp with no arguments starts the MCP stdio server.

What this is not

This is not the UseQR product app. Accounts, billing, public pages, and destination edits live at useqr.co. See useqr.co/mcp for the hosted server card and product brief.

The live product card uses namespace co.useqr/mcp. This OSS listing uses the GitHub namespace io.github.aaronte/useqr-mcp and points at the same hosted remote.
