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):
``json
{
"mcpServers": {
"Omdaa": {
"url": "https://omdaa.com/api/v1/mcp",
"headers": {
"Authorization": "Bearer YOUR_OMDAA_API_KEY"
}
}
}
}
`
4. Restart Cursor MCP / reload window
5. Ask: “List my Omdaa MCP tools” or call get_health

Example agent prompts
`text
Create a WhatsApp session named support, return the QR, then pause until connected.
`
`text
Set webhook to https://omdaa.com/n8n/webhook/omdaa-whatsapp for message.received events and test it.
`
`text
Send "Hello from Cursor MCP" to 201234567890 on session default.
`
`text
Create mailbox hello@omdaa.com and show IMAP settings.
`
Pair with the JS SDK
When you need scripts outside the editor:
`bash
npm install @omdaafreeapi/omdaa-api-client
`
`javascript
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'],
});
`
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`)
