Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Whatsapp account to Claude via Composio Connect, enabling it to send contact card to new lead, get business profile details for support, list all approved message templates, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Whatsapp account

Back in Claude, ask it to connect to Whatsapp or give it any Whatsapp-related task.

For example, ask Claude 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 Claude, and your Whatsapp account is ready to use.

What is the Whatsapp Claude Connector, 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.

Troubleshooting

1. Why does Claude not use the Composio connector for Whatsapp?

The connector can show as connected, but Claude must use it in each Whatsapp conversation.

Click + at the lower left of the chat, or type /.
Hover Connectors.
Turn on Composio.
Ask Claude to connect to Whatsapp again.

2. Why does Claude show an MCP server error before Whatsapp connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Whatsapp.

Check that the connector URL is https://connect.composio.dev/mcp.
Connectors run from Anthropic's cloud, so your device network is usually not the problem.
Add the connector again from Customize > Connectors, then ask Claude to connect Whatsapp.
If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Whatsapp authorization link not work?

The Composio connector is one server. Your Whatsapp account connects separately when Claude asks for it.

If the browser does not open, or the link expires, ask Claude to retry the Whatsapp connection.
Composio creates a fresh Whatsapp authorization link.
Open that link in your browser and finish the Whatsapp sign-in.

4. Why do Whatsapp actions fail after they worked before?

The Whatsapp connection can expire or lose permission.

Ask Claude to inspect the Whatsapp connection.
If the connection is unhealthy, disconnect it when Claude prompts you.
Reconnect the Whatsapp account and retry the action.
If Claude shows a permission prompt, approve it before Claude changes data in Whatsapp.
If the action still fails with a permission error, check that the connected account has that permission in Whatsapp itself.

5. How do I switch to a different Whatsapp account?

Claude can manage the Whatsapp connection for you.

Ask Claude to disconnect or delete the current Whatsapp account.
Ask Claude to connect Whatsapp again.
Open the new Composio authorization link for Whatsapp.
Sign in with the other Whatsapp account in the browser.
After the account connects, ask Claude to retry the Whatsapp task.

6. Why is my Whatsapp connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Whatsapp connection works in Claude Web, Desktop, and Cowork.

In Claude Desktop, open Customize > Connectors.
Next to Composio, click ⋮ and click Clear cache.
If Whatsapp tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Whatsapp.

FAQ

Frequently asked questions

With a standalone Whatsapp MCP server, the agents and LLMs can only access a fixed set of Whatsapp tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Whatsapp and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Whatsapp tools.
