4. Connect your Sideshow account

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

For example, ask Cowork to:

  • "Create design review post for team"
  • "Update roadmap post with blockers"
  • "Summarize comments on launch surface"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your Sideshow 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 Sideshow through MCP without you sharing account credentials directly with the agent.

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

The Sideshow MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Sideshow account. It provides structured and secure access to your collaborative visual workspace, so your agent can publish posts, update surfaces, browse workspace content, manage discussions, and remove content on your behalf.

  • Visual post publishing: Have your agent publish posts with one or more ordered, interactive surfaces in a new or existing workspace session.
  • Post updates and history: Direct your agent to revise post titles or surface content while preserving earlier versions for reference.
  • Workspace discovery: Let the agent browse sessions, review recent posts, retrieve full post content and version history, and find available presentation kits.
  • Collaborative discussions: Instruct your agent to add comments to posts, review existing discussions, or remove comments that are no longer needed.
  • Content cleanup: Have your agent permanently delete outdated or unwanted posts from the workspace.

FAQ

Frequently asked questions

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

Yes, absolutely. You can configure which Sideshow 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 Sideshow 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.
