Cursor's MCP support lets you connect external data sources directly to the AI panel. Add InstantReply once and Cursor can read every WhatsApp chat, Instagram DM, and Messenger thread — draft and send replies without leaving the editor.

~/.cursor/mcp_servers.json
{
"mcpServers": {
"instantreply": {
"command": "npx",
"args": [
"-y",
"@instantreply/mcp"
],
"env": {
"INSTANTREPLY_API_KEY": "ir_live_YOUR_KEY_HERE"
}
}
}
}Swap ir_live_YOUR_KEY_HERE for your key from the dashboard. Restart Cursor. Try it.
What you can ask
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.
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.
Use a key starting with ir_test_. Cursor calls the live API. Nothing ships to real customers. Build your webhook handler or custom flow with real data in a clean sandbox.
Why InstantReply
Most teams bolt five tools together and still miss leads. InstantReply ships all of it in one inbox your Cursor can call directly.
