Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Gamma account to Claude via Composio Connect, enabling it to create a pitch deck for a startup idea, generate an interactive onboarding presentation, summarize a research paper as slides, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Gamma account

Back in Claude, ask it to connect to Gamma or give it any Gamma-related task.

For example, ask Claude to:

  • "Create a pitch deck for a startup idea"
  • "Generate an interactive onboarding presentation"
  • "Summarize a research paper as slides"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Gamma account is ready to use.

What is the Gamma Claude Connector, and what's possible with it?

The Gamma MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Gamma account. It provides structured and secure access to Gamma’s AI-powered content creation platform, so your agent can generate new presentations, monitor generation progress, and retrieve finished files on your behalf.

  • AI-driven presentation generation: Instantly create beautiful, interactive decks or documents through simple prompts, letting your agent handle the heavy lifting.
  • Automated content creation: Ask your agent to produce engaging summaries, reports, or educational material as shareable Gamma presentations.
  • Real-time generation status tracking: Have your agent monitor the progress of each presentation request and keep you updated on completion status.
  • Direct retrieval of generated files: Let your agent fetch download URLs for finished Gamma files, making it easy to share or embed them anywhere.

Troubleshooting

1. Why does Claude not use the Composio connector for Gamma?

The connector can show as connected, but Claude must use it in each Gamma conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Gamma again.

2. Why does Claude show an MCP server error before Gamma connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Gamma.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Gamma.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Gamma authorization link not work?

The Composio connector is one server. Your Gamma account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Gamma connection.
  • Composio creates a fresh Gamma authorization link.
  • Open that link in your browser and finish the Gamma sign-in.

4. Why do Gamma actions fail after they worked before?

The Gamma connection can expire or lose permission.

  • Ask Claude to inspect the Gamma connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Gamma account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Gamma.
  • If the action still fails with a permission error, check that the connected account has that permission in Gamma itself.

5. How do I switch to a different Gamma account?

Claude can manage the Gamma connection for you.

  • Ask Claude to disconnect or delete the current Gamma account.
  • Ask Claude to connect Gamma again.
  • Open the new Composio authorization link for Gamma.
  • Sign in with the other Gamma account in the browser.
  • After the account connects, ask Claude to retry the Gamma task.

6. Why is my Gamma connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Gamma connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Gamma tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Gamma.

FAQ

Frequently asked questions

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

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