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 Bread & Butter through MCP without you sharing account credentials directly with the agent.

What is the Bread & Butter MCP server, and what's possible with it?

The Bread & Butter MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Bread & Butter account. It provides structured and secure access to your applications, leads, visitor activity, attribution data, and user insights, so your agent can review application settings, find leads, analyze events, assess attribution, and summarize visitor journeys on your behalf.

  • Lead and visitor research: Have your agent list lead and visitor profiles, find profiles by email address, and review saved lead lists.
  • Attribution reporting: Let the agent retrieve visitor and conversion attribution metrics by reporting period and source.
  • User journey insights: Direct your agent to summarize attribution and user journey trends, including top pages and geographic details when needed.
  • Activity event review: Instruct your agent to list tracked events by user or date range and review the event definitions configured for your application.
  • Application overview: Have your agent list available applications and review settings, feature flags, plan details, and lead status definitions.

FAQ

Frequently asked questions

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

Yes, absolutely. You can configure which Bread & Butter 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 Bread & Butter 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.
