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

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

The Lucid MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Lucid account. It provides structured and secure access so your agent can perform Lucid operations on your behalf.

FAQ

Frequently asked questions

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

Yes, absolutely. You can configure which Lucid 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 Lucid data and credentials are handled as safely as possible.
