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)

Open Cursor Directory → omdaa-api → Add to Cursor
Get an API key from Dashboard → API Keys
Set auth (prefer header, not query string):

{ "mcpServers": { "Omdaa": { "url": "https://omdaa.com/api/v1/mcp", "headers": { "Authorization": "Bearer YOUR_OMDAA_API_KEY" } } } }

Restart Cursor MCP / reload window
Ask: “List my Omdaa MCP tools” or call get_health

Pair with the JS SDK

When you need scripts outside the editor:

npm install @omdaafreeapi/omdaa-api-client

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'], });
