Connect Windsurf to WhatsApp Business
One line gives Windsurf your WhatsApp Business account as tools: 6 endpoints, send message, media, templates, called with your own connection. No key in the prompt, a receipt for every call, revoke Windsurf's access alone any time.
Three steps
- Create a free 0n3 account and connect WhatsApp Business. Paste a key or sign in; it lands in your vault, encrypted.
- Install 0n3 into Windsurf. The mcp_config.json block.
- Ask Windsurf: whoami. Then: "Send a text message in WhatsApp Business".
Write it yourself · ~/.codeium/windsurf/mcp_config.json
{
"mcpServers": {
"0n3": {
"serverUrl": "https://0n3.app/mcp",
"headers": {
"Authorization": "Bearer <your 0n token>"
}
}
}
}The line above carries a placeholder; 0n3.app/install mints a real key named for Windsurf and fills it in.
