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

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

The Amazing Marvin MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Amazing Marvin account. It provides structured and secure access to your tasks, projects, planning items, reminders, labels, and time tracking, so your agent can create and complete tasks, organize projects, manage reminders, review plans, and track time on your behalf.

  • Task and project management: Have your agent create tasks and projects with schedules, priorities, estimates, notes, labels, and project organization, or mark finished tasks complete.
  • Planning and workload review: Let the agent list open items, check what is scheduled for a specific date, or review work due by a chosen date.
  • Reminder management: Direct your agent to review scheduled reminders, set mobile push reminders, replace existing reminders, or delete reminders you no longer need.
  • Time tracking control: Instruct your agent to check which task is currently being tracked, start tracking time for a task, or stop the active timer.
  • Category and label organization: Have your agent list your available categories or labels, then use them to organize new tasks and projects.

FAQ

Frequently asked questions

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

Yes, absolutely. You can configure which Amazing Marvin 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 Amazing Marvin 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.
