Connect Muse to Whatsapp MCP. Send contact card to new lead, get business profile details for support, and more using natural language, with authentication handled for you.
WhatsApp is a business messaging platform for secure, automated customer communication. It streamlines chat workflows and customer outreach using the WhatsApp Business API.
Muse is Meta's AI assistant. It can connect to outside tools through custom connectors, which use the Model Context Protocol (MCP).
This guide explains how to connect Whatsapp to Muse using Composio Connect, which handles OAuth, token refresh, and reliability so you do not have to. You add Composio as a custom connector once, then ask Muse to work with Whatsapp in plain language.
For exact tool slugs and parameter tables, see the tool catalog in the Composio docs.
You add Composio to Muse once as a custom connector, then connect Whatsapp from the chat.
Start a new Muse chat and send this message. Muse builds the connector and shows a button to add your API key.
Create a Custom Connector for the Composio remote MCP server and connect to it:
- Name: Composio
- Transport: remote streamable HTTP
- URL: https://connect.composio.dev/mcp
- Auth: API key sent in the x-consumer-api-key header
Open the secure credentials store so I can enter the API key there, not in this chat. Then list its tools to confirm the connection works.Open the Muse page in your Composio dashboard and copy your API key. It starts with ck_.
Don't paste it into the chat. It goes in Muse's secure credentials store in the next step.
Tap the button Muse shows to open Add custom connector, paste your API key, then tap Add. Muse lists the Composio tools once it connects.
Back in the chat, ask Muse to connect to Whatsapp or give it any Whatsapp task.
For example, ask it to:
It will prompt you to authenticate and authorize access.
That's it. Composio's tools are now available in Muse, and your Whatsapp account is ready to use.
The WhatsApp MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your WhatsApp account. It provides structured and secure access to your WhatsApp Business account settings, profiles, templates, flows, and phone configuration, so your agent can manage business details, register phone numbers, maintain templates, update flows, and review account settings on your behalf.
Now that Whatsapp is connected, extend your setup by connecting the other apps you already use every day, so Muse can run true cross-app workflows end to end.
Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single connection, Muse can coordinate multiple tools safely and reliably in one conversation.
Muse shows the button only when you ask it to open the secure credentials store.
The key or the connector settings are not correct.
ck_.https://connect.composio.dev/mcp and the header is x-consumer-api-key.Muse may not pick the Composio connector for the request.
Your Whatsapp connection expired or was removed.
Treat the key as exposed.
Every Whatsapp action and event your agent gets out of the box.
