# Give your AI agent WhatsApp and email: is it really that easy? > One hosted MCP server lets Claude, ChatGPT, Claude Code, Cursor or n8n send WhatsApp and email from your own number and mailbox. Setup and limits. Source: https://unlimitedmessaging.app/articles/ai-agent-email-whatsapp AI agents # Give your AI agent _WhatsApp and email_ One hosted MCP server, two channels, your own number and mailbox. Connect Claude, ChatGPT, Claude Code, Cursor or n8n in a few minutes, without running a WhatsApp bridge yourself. [Connect my agent](https://app.unlimitedmessaging.app)[See pricing](https://unlimitedmessaging.app/pricing) The idea ## What does it mean to give an agent WhatsApp and email? An AI agent is a model that can act: it calls tools, reads the result and decides the next step. Giving it WhatsApp and email means handing it tools to read and send messages on those two channels, and with the [Model Context Protocol](https://modelcontextprotocol.io) one server can provide both. Most setups today stitch several pieces together: a WhatsApp MCP server you host yourself, a separate email server for IMAP and SMTP, and a WhatsApp session to keep alive on your machine. Each has its own login, its own failure modes and its own idea of who a contact is. UnlimitedMessaging puts both channels behind one hosted server, https://mcp.unlimitedmessaging.app. The agent sees a send-message tool that sends WhatsApp, email or both, from your own WhatsApp number and your own mailbox, and a list-messages tool that reads what came back. Nothing to run, and OAuth instead of keys pasted into a config file. MCP is now hosted by the Linux Foundation's Agentic AI Foundation, which counted more than 10,000 active servers in December 2025\. Claude, ChatGPT, Claude Code and Cursor all speak it. For tools that don't, the same actions exist as a REST API, TypeScript and Python SDKs and an n8n node. ![Illustration: an envelope in front of an inbox, with the headline “Your AI agent, on WhatsApp and email”.](https://unlimitedmessaging.app/_next/image?url=%2Fassets%2Farticles%2Fcovers%2Fai-agent-email-whatsapp-en.png&w=3840&q=75) Definition AI agent An AI model that reaches a goal in several steps by calling tools, reading their results and choosing what to do next, instead of answering a single prompt. Also called agentic AI or a tool-using assistant. [Source: Model Context Protocol↗](https://modelcontextprotocol.io) Use cases ## What agents do with WhatsApp and email * Tell you on WhatsApp when a long Claude Code task finishes or fails, so you can leave your desk. * Prepare a morning digest of unanswered emails and WhatsApp messages, with drafted replies for you to approve. * Follow up a lead: a short WhatsApp message and the quote by email, in the same request, from your own accounts. * Read a support inbox and answer on the channel the customer used, with a human checking before anything goes out. Two ways to wire it ## Self-hosted MCP servers or one hosted server Open-source WhatsApp and email MCP servers exist and work. Here is what changes when the two channels live in one hosted service. __Self-hosted MCP servers or one hosted server__ | Self-hosted serversone per channel, on your machine | UnlimitedMessaging MCPhosted, WhatsApp + email | | | --------------------------------------------------- | ---------------------------------------------- | -------------------------------------------------- | | Channels | One server per channel | WhatsApp and email in one server | | Hosting | Your computer or a VPS, always on | Hosted, nothing to run | | WhatsApp session | A local bridge you restart and re-link | Kept online by the service | | Sign-in | Tokens or passwords in a config file | OAuth, revocable from your account | | Incoming messages | The agent polls the bridge | list-messages tool, or a webhook on Medium and Max | | Cost | Free software, your infrastructure | Free plan, Medium at €19 or Max at €29 a month | Setup ## Connect your agent in a few minutes 1. 01 ### Link your accounts Create a free account at app.unlimitedmessaging.app, scan the QR code to link your WhatsApp number, and connect your mailbox over IMAP/SMTP (Gmail with an app password, or any provider). 2. 02 ### Claude or ChatGPT Add a connector with the URL https://mcp.unlimitedmessaging.app, then approve the OAuth sign-in. See our Claude and ChatGPT guides for the screens. 3. 03 ### Claude Code Run: claude mcp add --transport http unlimited-messaging https://mcp.unlimitedmessaging.app - then type /mcp in a session and sign in in the browser. 4. 04 ### Cursor Add the server to .cursor/mcp.json: {"mcpServers": {"unlimited-messaging": {"url": "https://mcp.unlimitedmessaging.app"}}} - Cursor lists its tools once you sign in. 5. 05 ### n8n or your own code Use the n8n-nodes-unlimited-messaging node, or call POST /message from the REST API or the TypeScript and Python SDKs. Good to know ### Keep a human in the loop An agent sends from your real number and address. Have it show you a new message before sending, keep it to people who expect to hear from you, and never use it for bulk messages: WhatsApp's terms forbid automated spam. UnlimitedMessaging is not affiliated with Meta, Anthropic or OpenAI. FAQ ## AI agents, WhatsApp and email: your questions Yes. Add the MCP server to Claude Code, then ask it to message you on WhatsApp at the end of the task, or write that instruction in your project's CLAUDE.md. The message comes from your own linked number. No. You link your normal WhatsApp or WhatsApp Business app number by QR code. The Meta Business API, its templates and its verification are not involved. List your accounts, read an account, link a WhatsApp number or a mailbox, list and read messages, and send a message on WhatsApp, email or both. MCP access is included in every plan, the Free plan too. Paid plans add throughput, webhooks and remove the small "Sent with UnlimitedMessaging.app" footer. It can read them with list-messages whenever it runs. To react as they arrive, use a webhook (Medium and Max plans) that triggers your agent, for example from n8n. Keep a human check before anything goes out. Sources ## Sources & references To check the information in this article for yourself: 1.
