Windsurf's Cascade agent supports MCP servers natively. Add one block to the Windsurf config and Cascade can read every WhatsApp chat, Instagram DM, and Messenger thread — then draft and send replies as part of any agentic flow.

~/.codeium/windsurf/mcp_config.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 Windsurf. Try it.
What you can ask
Build a multi-step flow. Step one fetches today's open WhatsApp chats. Step two tags hot leads by temperature. Step three drafts replies with your AI Brain. Cascade runs all three and waits for your approval.
Ask Cascade: show me today's Instagram DMs from hot leads. It pulls the list, shows the last message from each, and lets you reply inline. No switching tabs. No copy-pasting.
Tell Cascade to rewrite pending replies in a warmer tone using your AI Brain. Review all 20 in one panel. Approve and they send across WhatsApp, Instagram, and Messenger.
