Google Chat is Google Workspace's messaging and collaboration service for teams. It keeps conversations, spaces, files, and work updates in one shared place.

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 Google Chat account to Claude via Composio Connect, enabling it to summarize recent messages in project space, send standup reminder to engineering space, list members of support chat space, 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 Google Chat account

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

For example, ask Claude to:

  • "Summarize recent messages in project space"
  • "Send standup reminder to engineering space"
  • "List members of support chat space"

It will prompt you to authenticate and authorize access.

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

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

The Google Chat MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Google Chat account. It provides structured and secure access so your agent can perform Google Chat operations on your behalf.

Troubleshooting

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

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

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

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

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

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

3. Why does the Google Chat authorization link not work?

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

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

4. Why do Google Chat actions fail after they worked before?

The Google Chat connection can expire or lose permission.

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

5. How do I switch to a different Google Chat account?

Claude can manage the Google Chat connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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