Cursor MCP server for WhatsApp and Instagram DMs.
Cursor's MCP support lets you connect external data sources directly to the AI panel. Add InstantReply once and Cursor can use the inbox tools allowed by your plan, connected channels, API-key scopes, and rate limits. Write tools require an eligible paid plan and write scope.

What you can ask
Three things Cursor can do today.
- 01
Close a WhatsApp lead without breaking flow
You are mid-feature. A hot lead messages. Open the Cursor AI panel, type one prompt: reply to that WhatsApp lead. Cursor pulls the chat history, drafts the reply using your AI Brain, and sends after you confirm.
- 02
Triage today's Instagram DMs from the editor
Ask Cursor: show me today's open Instagram DMs sorted by lead temperature. It lists hot leads first with their last message. Pick which ones to close now - no tab switching.
- 03
Test outbound flows without live data
Use a key starting with ir_test_ for documented synthetic send and trigger simulations. Live tenant reads and every other operation are rejected.
