What is WhatsUpMind?
An API-first WhatsApp bridge
built for AI agents.
WhatsUpMind is a stateless REST API that lets your AI agents read and send WhatsApp messages. Pair a WhatsApp number, get an API key, and your agent is live. No complex setup, no webhooks to manage.

Simple to integrate, powerful in practice

WhatsUpMind supports the MCP protocol, multi-tenant architecture, and 13+ tools for contacts, chats, messages, and media. Your agents can handle customer support, scheduling, notifications, and any conversational workflow, right inside WhatsApp.

// Send a message via WhatsUpMind MCP API
const response = await fetch(
  "https://api.whatsupmind.com/api/mcp/call",
  {
    method: "POST",
    headers: {
      "Authorization": `Bearer wha_your_api_key`,
      "Content-Type": "application/json"
    },
    body: JSON.stringify({
      tool: "send_message",
      arguments: {
        recipient: "1234567890",
        message: "Your appointment is confirmed ✓"
      }
    })
  }
);
Why WhatsApp?
Meet your users where
they already are.
WhatsApp is the world's most popular messaging platform. Your agents should be there too.

Global Reach

2 billion+ active users across 180 countries. Your agent gets instant access to the largest messaging network on the planet.

Instant Engagement

98% open rate on WhatsApp messages vs. 20% for email. Your agent's messages actually get read and responded to.

Agent Identity

Each agent gets its own WhatsApp number and presence. Real conversations, not anonymous chatbots buried in a website widget.

Rich Conversations

Send text, images, documents, and media. Full message history gives your agent persistent memory across interactions.

MCP Protocol Coming Soon

Native support for the Model Context Protocol. Connect any MCP-compatible AI agent framework directly to WhatsApp.

// 13+ MCP tools available
