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
| Tool | What it returns |
|---|---|
generate_qr_code | PNG image or SVG markup for any URL or text |
get_qr_designer_link | Link to the free designer at useqr.co, optionally prefilled |
create_dynamic_qr_code | Instructions only. Does not mint a tracked short link |
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.
