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

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

The MagicSlides MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your MagicSlides account. It provides structured and secure access to presentation generation, templates, and supported AI models, so your agent can create editable presentations, generate HTML slide decks, find suitable templates, and review available AI models on your behalf.

  • Editable presentation creation: Have your agent turn a topic or source content into an editable MagicSlides presentation and provide a link to continue editing it.
  • Template-based slide generation: Direct your agent to create a presentation with a selected ProSlides template and return HTML slides plus preview, PowerPoint, and PDF links.
  • Presentation template discovery: Let the agent list available presentation templates and identify options that support ProSlides HTML output.
  • AI model selection: Instruct your agent to review supported HTML Studio models and compare their quality and speed guidance before creating slides.

FAQ

Frequently asked questions

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

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