4. Connect your OpenUI Cloud account

Back in Cowork, ask the agent to connect to OpenUI Cloud or give it any OpenUI Cloud-related task.

For example, ask Cowork to:

  • "Generate interactive SaaS pricing dashboard"
  • "Create onboarding wizard UI artifact"
  • "Summarize recent OpenUI Cloud conversations"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your OpenUI Cloud account is ready to use.

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 OpenUI Cloud through MCP without you sharing account credentials directly with the agent.

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

The OpenUI Cloud MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your OpenUI Cloud account. It provides structured and secure access to generated interfaces, managed conversations, and persisted artifacts, so your agent can generate interactive interfaces, organize conversations, review conversation history, find artifacts, and retrieve renderable content on your behalf.

  • Interactive interface generation: Have your agent turn text or structured instructions into interactive user interface responses.
  • Conversation organization: Let the agent create conversations, list existing ones, rename them, or delete conversations you no longer need.
  • Conversation history review: Direct your agent to read persisted messages and function call activity from a managed conversation.
  • Artifact discovery: Instruct your agent to list saved artifacts and narrow the results by name or artifact type.
  • Renderable artifact retrieval: Have your agent retrieve a saved artifact with its complete renderable content for review or reuse.

FAQ

Frequently asked questions

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

Yes, absolutely. You can configure which OpenUI Cloud 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 OpenUI Cloud 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.
