Qrblox tools (14, 5 write)

write = sends, deletes, buys or posts
  • qrblox.analytics.scan_summaryFree

    Summarize recent scan activity for a merchant workspace.

  • qrblox.audio.createwrite actionFree

    Create a draft audio code payload that can later be published as a near-ultrasonic sharing experience.

  • qrblox.challenge.createwrite actionFree

    Create a draft scan challenge, streak, game, or loyalty campaign.

  • qrblox.menu.add_itemFree

    Add an item to a section in an existing merchant menu.

  • qrblox.menu.createwrite actionFree

    Create a merchant menu that can be connected to QR codes, audio codes, and scan experiences.

  • qrblox.menu.listFree

    List recent menus for the merchant.

  • qrblox.merchant.get_profileFree

    Get the merchant workspace attached to this user or API key.

  • qrblox.pingFree

    Confirm that the Qrblox MCP server is reachable for the authenticated merchant.

  • qrblox.qr.createwrite actionFree

    Create a finished QR code: returns a hosted PNG (qrImageUrl) plus, for dynamic codes, a qrb.dev dynamic link you can re-point later. Options: template wraps the code in a Qrblox hex frame; boostFrame renders a scan-to-earn reward frame (scans through the Qrblox app award boosted points); scanBeepSound makes the Qrblox app play that sound on every scan (forces dynamic). Plain calls with none of these return a simple static code.

  • qrblox.qr.get_analyticsFree

    Per-code scan report from the Qrblox analytics pipeline: total scans, daily counts, and every scan with date and city/state. Works for dynamic codes and app-scanned codes (last 365 days max).

  • qrblox.qr.listFree

    List recent QR codes for the merchant.

  • qrblox.qr.updatewrite actionFree

    Edit an existing QR code: re-point the destination URL (dynamic codes redirect immediately, no reprint), change the scan sound, or rename it. Identify the code by codeId (from qr.create/qr.list) or uniqueQRCodeID.

  • qrblox.voice_agent.lookupFree

    Look up a business in the Qrblox Voice Agent Phone Book by website domain — returns their confirmed AI voice agent phone number if registered.

  • qrblox.voice_agent.registerFree

    Register a business's AI voice agent phone number and domain in the Qrblox Voice Agent Phone Book directory (free; creates a backlink page at qrblox.com/d/<domain> once approved).

What the publisher says

From the Qrblox repository's README, as published. We do not edit it. Read it on GitHub

Qrblox MCP

The Model Context Protocol server for Qrblox — let any MCP-aware AI agent generate and manage QR codes, audio codes, menus, and loyalty campaigns.

📚 Full reference: docs.qrblox.com/mcp.html 🌐 Endpoint: https://app.qrblox.com/api/mcp 🔑 Mint a key: create.qrblox.com/settings/api-keys 🟢 No-key sandbox: POST https://app.qrblox.com/api/generate-qr-code

This is a public, README-only repo. The MCP server itself is

deployed at the endpoint above; the canonical docs live at

docs.qrblox.com/mcp.html.

What is it?

qrblox-mcp is a JSON-RPC 2.0 MCP server. Point Claude Desktop, Cursor, Codex, or any MCP client at https://app.qrblox.com/api/mcp, paste in a sk-qrblox- key, and the assistant can immediately draft QR codes (and audio codes, menus, and loyalty campaigns) and read scan analytics on a merchant workspace.

Every code created via the MCP lives on the caller's Qrblox account alongside codes made from the iOS, Android, Canva, and web surfaces.

Quick start

1. Try it free (no signup, no OAuth)

curl -X POST https://app.qrblox.com/api/generate-qr-code \
  -H 'content-type: application/json' \
  -d '{"url":"https://example.com"}'

Returns:

{
  "ok": true,
  "code": {
    "codeId": "…",
    "destinationUrl": "https://example.com",
    "qrImage":    "data:image/png;base64,…",            // inline PNG
    "qrImageUrl": "https://storage.googleapis.com/…",    // hosted PNG
    "claimToken": "…",
    "expiresAt":  "…"
  },
  "upgrade": { "signup": "https://app.qrblox.com", "apiKeys": "https://create.qrblox.com/settings/api-keys" }
}

Sandbox limits: 3 codes / IP / day, codes expire in 7 days.

2. Mint an API key

Sign in to create.qrblox.com → Settings → API keys → New API key. Keys are sk-qrblox-<64 hex chars>, shown once, and revocable anytime.

3. Connect Claude Desktop

// ~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "qrblox": {
      "url": "https://app.qrblox.com/api/mcp",
      "headers": {
        "Authorization": "Bearer sk-qrblox-..."
      }
    }
  }
}

Restart Claude Desktop. Then ask: "Generate a QR code for https://my-spring-menu.com."

4. Or Cursor / Codex / curl

Same URL, same Authorization header.

# tools/list — no auth required
curl -X POST https://app.qrblox.com/api/mcp \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

# tools/call — create a code on your account
curl -X POST https://app.qrblox.com/api/mcp \
  -H 'authorization: Bearer sk-qrblox-...' \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call",
       "params":{"name":"qrblox.qr.create",
                 "arguments":{"title":"Spring menu",
                              "destinationUrl":"https://qrblox.com/menu/spring"}}}'

Tools

All tools are merchant-scoped and draft-first — agents propose, the merchant approves before publishing.

Plus two REST endpoints for non-MCP callers:
