Cursor MCP WhatsApp: 109 Free Tools (Wassenger Alternative)

Want WhatsApp + Mail inside Cursor without an Enterprise MCP plan? Omdaa's free Cursor MCP plugin exposes 109 tools (v2.3.0) over Streamable HTTP — sessions, inbox, groups, bulk, webhooks, Omdaa AI, and Omdaa Mail.

Series: Free Forever WhatsApp Dev · Install: cursor.directory/plugins/omdaa-api

Why this matters in 2026

AI editors are becoming the control plane. Instead of clicking dashboards, you tell the agent:

“Create a WhatsApp session, show QR, set webhook to n8n, and enable Omdaa AI.”

Omdaa MCP does that free forever — a practical alternative to paid WhatsApp MCP offerings.

Install (2 minutes)

  1. Open Cursor Directory → omdaa-api → Add to Cursor
  2. Get an API key from Dashboard → API Keys
  3. Set auth (prefer header, not query string): 
{
  "mcpServers": {
    "Omdaa": {
      "url": "https://omdaa.com/api/v1/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_OMDAA_API_KEY"
      }
    }
  }
}
Enter fullscreen mode Exit fullscreen mode
  1. Restart Cursor MCP / reload window
  2. Ask: “List my Omdaa MCP tools” or call get_health

What you can do (tool groups)

Area Examples
Sessions create_session, get_qr, get_connection_state, logout_session

Pair with the JS SDK

When you need scripts outside the editor:

npm install @omdaafreeapi/omdaa-api-client
Enter fullscreen mode Exit fullscreen mode 
const { OmdaaClient } = require('@omdaafreeapi/omdaa-api-client');
const client = new OmdaaClient({ apiKey: process.env.OMDAA_API_KEY });
await client.webhooks.set({
  url: 'https://omdaa.com/n8n/webhook/omdaa-whatsapp',
  enabled: true,
  events: ['message.received'],
});
Enter fullscreen mode Exit fullscreen mode

Security tips

  • Prefer Authorization: Bearer headers — avoid ?key= in URLs
  • Rotate keys from Dashboard → API Keys
  • Scope bots with least privilege sessions
  • Verify webhook HMAC (X-Webhook-Signature)
