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_ for documented synthetic send and trigger simulations. Live tenant reads and every other operation are rejected.
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.
