Connect Cursor to WhatsApp via MCP

Cursor is an AI-powered code editor that supports MCP servers. With Pons, you can check WhatsApp Business messages, search conversations, and send quick replies — all from within your editor.

Prerequisites

• Cursor installed
• A Pons account at pons.chat with a WhatsApp Business number connected (setup guide)

Step 1: Create an API key

1. Sign in to pons.chat
2. Click the key icon to open the API Key Manager
3. Click Create Key with the scopes you need
4. Copy the key

Step 2: Configure Cursor

You have two options:

Option A: Cursor Settings UI

1. Open Cursor Settings → MCP Servers
2. Click Add Server
3. Fill in:
   • Type: HTTP
   • URL: https://pons.chat/api/mcp
   • Headers: Authorization: Bearer pons_your_api_key_here

Option B: Project config file

Create .cursor/mcp.json in your project root:

{
  "mcpServers": {
    "pons": {
      "url": "https://pons.chat/api/mcp",
      "headers": {
        "Authorization": "Bearer pons_your_api_key_here"
      }
    }
  }
}

The project config approach is useful if you want Pons available only in specific projects. Use the Settings UI for global access.

Step 3: Use it

In Cursor's AI chat, ask:

"Check my WhatsApp messages"

Cursor will call the Pons tools and show your recent conversations.

More examples:

• "Any unanswered WhatsApp messages?"
• "Search WhatsApp for 'bug report'"
• "Reply to that conversation with 'Fix is deployed, can you test?'"
• "Send the status update template to +49123456789"

Why WhatsApp in your editor?

If you're building a product and your customers or team communicate via WhatsApp, having access inside your editor means fewer context switches. Get a bug report on WhatsApp, find the relevant code, fix it, and reply "deployed" — all without leaving Cursor.

Scopes

Create a minimal key for your use case:

• Just reading: read scope only — browse conversations, search messages
• Reading + reacting: read + write scopes — also mark as read and react with emoji
• Full access: all three scopes — includes sending messages

See the API Keys guide for details on scopes and key management.
