Introduction

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.

Why use Composio?

  • Cross-app workflows across 1,500+ apps from a single plugin layer.
  • On-demand tool loading so Muse only loads the tools needed for the current task.
  • Programmatic tool calling through a remote workbench for complex, multi-step workflows.
  • Multi-account support so users can connect and switch between multiple accounts for the same app.
  • Shared account access so teams or agents can work through common business accounts and service connections.
  • Managed authentication with OAuth handling, credential storage, and token refresh managed by Composio.
  • Safer credential handling so app credentials stay outside the model context and tool responses.
  • User-level account isolation so actions run against the correct connected account instead of mixing user access.

Connecting Whatsapp to Muse

You add Composio to Muse once as a custom connector, then connect Whatsapp from the chat.

1. Ask Muse to connect to Composio

Start a new Muse chat and send this message. Muse builds the connector and shows a button to add your API key.

bash
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.

2. Copy your API key

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.

3. Add your API key in the secure credentials store

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.

Muse secure credentials store with the connect.composio.dev URL, an API Key field, and the Add button

4. Connect your Whatsapp account

Back in the chat, ask Muse to connect to Whatsapp or give it any Whatsapp task.

For example, ask it to:

  • "Send contact card to new lead"
  • "Get business profile details for support"
  • "List all approved message templates"

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.

What is the Whatsapp MCP server, and what's possible with it?

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.

  • Business profile management: Have your agent update your business description, contact information, and other WhatsApp Business profile settings.
  • Phone number administration: Direct your agent to register or deregister a WhatsApp Business phone number and set its two-step verification PIN.
  • Message template management: Let the agent browse the template library and create or update templates for your WhatsApp Business account.
  • Flow and commerce configuration: Instruct your agent to review Flow assets, update Flow configurations, and check commerce settings for your business phone number.
  • Account oversight and access: Have your agent review owned or shared business accounts, inspect compliance and encryption details, manage assigned user access, and subscribe your application to account notifications.

Way Forward

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.

  • Connect Calendar to turn threads into scheduled meetings automatically.
  • Connect Slack or Teams to post summaries, approvals, and alerts where your team works.
  • Connect Notion, Linear, Jira, or Asana to convert requests into tickets, tasks, and docs.
  • Connect Drive, Dropbox, or OneDrive to fetch, file, and share attachments without manual steps.

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.

Troubleshooting

1. Why doesn't Muse show a button to add my API key?

Muse shows the button only when you ask it to open the secure credentials store.

  • Start a new chat.
  • Send the message from step 1 exactly as written.
  • If Muse asks for the key in the chat, do not paste it. Ask Muse to open the secure credentials store.

2. Why does the Composio connection fail after I add my API key?

The key or the connector settings are not correct.

  • Copy the full key from the Composio dashboard. It starts with ck_.
  • Make sure the URL is https://connect.composio.dev/mcp and the header is x-consumer-api-key.
  • Remove the Composio connector in Muse settings, then do steps 1 to 3 again.

3. Why doesn't Muse use the Composio tools for Whatsapp?

Muse may not pick the Composio connector for the request.

  • Ask Muse to list its Composio tools.
  • Name Composio and Whatsapp in your request, for example: Use Composio to connect to Whatsapp.
  • If it still does not work, start a new chat and try again.

4. Why does Muse ask me to connect Whatsapp again?

Your Whatsapp connection expired or was removed.

  • Open the link Muse gives you and sign in to Whatsapp again.
  • Check that the Whatsapp connection shows as ACTIVE in the Composio dashboard.

5. What do I do if I pasted my API key into the chat?

Treat the key as exposed.

  • Create a new API key in the Composio dashboard and delete the old one.
  • Add the new key in Muse's secure credentials store, not in the chat.
