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 Tasks account to Claude via Composio Connect, enabling it to add a new task to your work list, list all tasks due this week, delete completed tasks from your shopping list, 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 Tasks account

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

For example, ask Claude to:

  • "Add a new task to your work list"
  • "List all tasks due this week"
  • "Delete completed tasks from your shopping list"

It will prompt you to authenticate and authorize access.

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

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

The Google Tasks 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 Tasks account. It provides structured and secure access to your to-do lists and tasks, so your agent can create task lists, add or update tasks, reorganize and clean up your lists, and fetch or manage your action items automatically.

  • Intelligent task list management: Ask your agent to create new to-do lists, fetch existing ones, or remove lists you no longer need—all without manual clicks.
  • Automated task creation and updates: Let your agent add new tasks, set due dates, or update existing to-dos to keep your lists current and organized.
  • Efficient task organization and movement: Move tasks between lists, reorder them, or set parent/child relationships so your priorities always stay clear.
  • Fast cleanup and deletion: Direct your agent to clear completed tasks or delete specific items and lists, helping you declutter swiftly and securely.
  • Detailed task retrieval and review: Have your agent pull details on any task or list so you can review upcoming deadlines, notes, and status at a glance.

Troubleshooting

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

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

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

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

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

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

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

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

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

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

The Google Tasks connection can expire or lose permission.

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

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

Claude can manage the Google Tasks connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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