[Create my account](https://app.unlimitedmessaging.app)[See pricing](https://unlimitedmessaging.app/pricing) Background ## What is an MCP connector for Claude? An "MCP connector" builds on the [Model Context Protocol](https://modelcontextprotocol.io), the open standard that lets Claude call external tools securely, directly from a conversation. The Model Context Protocol (MCP) was introduced by Anthropic as an open standard to connect AI assistants to the systems where data and actions live. Concretely, an MCP server exposes "tools" (for example "send a message", "list messages") that Claude can decide to call on its own, at the right moment, without you writing a single line of code. Unlimited Messaging is one of these servers: once added as a connector in Claude - whether in Claude Desktop or on claude.ai - it gives Claude controlled access to your WhatsApp. You stay in charge of authorization: the connection goes through an OAuth flow, and each sensitive action can ask for your confirmation before it runs. The result is an assistant that speaks WhatsApp in natural language. "Reply to this customer", "send Marie an appointment reminder tomorrow morning", "summarize my latest exchanges with the supplier": Claude reads, writes and reasons about your conversations - on your normal WhatsApp account, with no Meta business account, no template to get approved and no per-message billing. ![Illustration: a grid of small icons with one highlighted, with the headline “Ask Claude to send your WhatsApps”.](https://unlimitedmessaging.app/_next/image?url=%2Fassets%2Farticles%2Fcovers%2Fmcp-claude-en.png&w=3840&q=75) Definition MCP connector for Claude A Model Context Protocol-compatible service that Claude can query to act on an external system - here, your WhatsApp: send a message, read your conversations, list your accounts.
