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 Gemini account to Claude via Composio Connect, enabling it to summarize this research article in 100 words, generate a creative image of a futuristic city, create a 30-second video based on this script, 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.

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

3. Connect your Gemini account

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

For example, ask Claude to:

  • "Summarize this research article in 100 words"
  • "Generate a creative image of a futuristic city"
  • "Create a 30-second video based on this script"

It will prompt you to authenticate and authorize access.

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

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

The Gemini MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Gemini account. It provides structured and secure access to Gemini's multimodal AI features, so your agent can generate text, images, and videos, analyze content, and manage model resources on your behalf.

  • Text and content generation: Instruct your agent to create high-quality, customized text using Gemini's advanced generative models—great for brainstorming, drafting, or summarizing information.
  • Creative image and video generation: Ask the agent to generate original images or high-quality videos from text prompts using Gemini 2.5 Flash and Veo models, with fine control over style and format.
  • Embedding and semantic analysis: Let your agent transform any text into rich semantic embeddings for similarity search, clustering, or classification tasks.
  • Model discovery and optimization: Have the agent list available Gemini and Veo models, check their capabilities, and select the best fit for your project or workflow.
  • Efficient resource management: Enable the agent to track video generation operations, download final assets, and optimize prompt inputs by counting tokens—all without manual intervention.

Troubleshooting

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

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

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

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

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

  • 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 Gemini.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Gemini authorization link not work?

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

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

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

The Gemini connection can expire or lose permission.

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

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

Claude can manage the Gemini connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click and click Clear cache.
  • If Gemini 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 Gemini.

FAQ

Frequently asked questions

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

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