What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.

With Composio Connect, Cowork can securely access apps like Wati through MCP without you sharing account credentials directly with the agent.

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

The Wati MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Wati WhatsApp Business account. It provides structured and secure access to your business messaging, so your agent can add contacts, send WhatsApp messages, update contact details, and retrieve team information automatically on your behalf.

  • Automated contact management: Have your agent add new WhatsApp contacts, ensuring customers are registered before any communication starts.
  • Proactive messaging via WhatsApp: Empower your agent to send session messages to customers for support, marketing, or updates within the active session window.
  • Contact attribute updates: Let your agent update existing contact information or custom attributes, so your customer data stays fresh and relevant.
  • Team coordination and retrieval: Quickly fetch lists of your Wati teams, making it easy for your agent to understand and act on organizational structure.

FAQ

Frequently asked questions

With a standalone Wati MCP server, the agents and LLMs can only access a fixed set of Wati tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Wati 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 Wati tools.

Yes, absolutely. You can configure which Wati scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Wati data and credentials are handled as safely as possible.

A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.

We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.

As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.

Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.
