Quality QR

Quality QR MCP Server

Create and manage trackable QR codes through AI assistants like Claude, Cursor, and any MCP-compatible tool.

Unlike generic QR code generators, Quality QR codes are saved to your account with scan tracking, analytics, and the ability to update destinations without reprinting.

Endpoint: https://quality-qr.app/api/mcp

Setup

1. Get an API Key

Sign up at quality-qr.app and generate an API key at Dashboard > Settings > API Keys.

2. Configure Your MCP Client

Smithery users: If you install via Smithery, you'll be prompted for your apiKey directly — Smithery handles the Authorization header for you. The configs below are for manual setup.

Claude Desktop

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on Mac):

{
  "mcpServers": {
    "quality-qr": {
      "url": "https://quality-qr.app/api/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Cursor

Add to your Cursor MCP settings:

{
  "mcpServers": {
    "quality-qr": {
      "url": "https://quality-qr.app/api/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Claude Code

claude mcp add quality-qr --transport http https://quality-qr.app/api/mcp \
  --header "Authorization: Bearer YOUR_API_KEY"

3. Start Using It

Ask your AI assistant:

• "Create a QR code for https://example.com";
• "Make a WiFi QR code for network MyWiFi with password guest123"
• "Show me the analytics for my QR codes"
• "List all my QR codes"
• "Disable QR code abc123"

Available Tools

QR Code Types

Dynamic (URL can be changed after printing): URL, PDF, Menu, App Store, Social

Static (data encoded directly): WiFi, vCard, Email, Phone, SMS, Text, Event

Rate Limits

MCP tool calls count against your API rate limit. Protocol messages (initialize, tools/list) are free.

Rate-Limit Response Headers

Every response includes headers to help you manage usage:

When you receive a 429 Too Many Requests response, wait for the number of seconds specified in Retry-After before retrying.

Security

• All requests authenticated via API key (Bearer token)
• Keys can be revoked instantly from the dashboard
• QR codes are scoped to your account (no cross-user access)
• No admin, billing, or team management operations exposed
• GDPR and CCPA compliant, hosted on Cloudflare's global edge network
• See SECURITY.md to report a vulnerability, and PRIVACY.md for data handling details

API Key Management

Your API key grants full access to your QR codes and analytics. Treat it like a password.

• Rotate regularly. Generate a new key in Dashboard > Settings > API Keys, update your MCP client config, then revoke the old key. You can have multiple active keys to allow zero-downtime rotation.
• Revoke compromised keys immediately. Revocation takes effect instantly — any in-flight requests using the old key will fail.
• Restrict access to config files. MCP client configs store your key in plaintext. On macOS/Linux, ensure only your user can read them (e.g., chmod 600). Avoid committing config files with real keys to version control.
