How to integrate Google Tasks MCP with ChatGPT

ChatGPT is one of the most popular AI tools today, with capabilities ranging from deep research and image generation to writing, coding, and everyday productivity.

In this guide, I will explain the easiest and most secure way to connect your Google Tasks account to ChatGPT via Composio Connect, so it can summarize unread updates from this morning, create draft replies to urgent messages, fetch contact details for recent senders, and more without ever putting your account credentials at risk.

Also integrate Google Tasks with

Why use Composio over default connectors?

  • Apps with read and write access. Default connectors mostly can read your data. Composio's Google Tasks integration lets ChatGPT take actions like creating drafts, sending updates, labeling records, and more.
  • 1,000+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce.
  • One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app.
  • Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand.
  • Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation.

Prerequisites

  • A ChatGPT account with Plus subscription or higher (Business, Enterprise, Edu, or Pro). We will use ChatGPT Web.
  • Access to the Google Tasks workspace you want to connect.
  • Composio MCP.

Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account.

Step-by-step: Connect Google Tasks to ChatGPT

1. Enable Developer Mode

In ChatGPT, go to Settings > Apps > Advanced settings and turn on Developer Mode.

2. Add the MCP server

Click Create app, then paste the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
ChatGPT create app flow with Composio MCP URL

3. Authorize in your browser

A browser window will open automatically. Sign in to authorize ChatGPT to access your Composio account.

4. Start using Composio

Composio tools are now available in ChatGPT chats and Deep Research. In every new chat, click the + icon at the bottom, click More, and select Composio to enable tools for that conversation.

What you can do after connecting Google Tasks

  • Add a new task to your work list
  • List all tasks due this week
  • Delete completed tasks from your shopping list
  • Move an urgent task to the top of your personal list

Security + privacy notes (important)

  • Use least-privilege access: Only grant permissions you actually need.
  • Review OAuth permissions before approving: Make sure requested scopes match what you expect Composio and ChatGPT to do.
  • Keep write actions human-reviewed: For actions like sending messages, creating labels, or editing drafts, keep manual confirmation enabled.
  • Be careful with sensitive data: Avoid using this setup with highly sensitive information unless allowed by your personal, company, or client policies.

Supported Tools & Triggers

Delete taskDeletes a specified task from a given task list in google tasks.
Delete task listPermanently deletes an existing google task list, identified by `tasklist id`, along with all its tasks; this operation is irreversible.
Get TaskUse to retrieve a specific google task if its `task id` and parent `tasklist id` are known.
Get task listRetrieves a specific task list from the user's google tasks if the `tasklist id` exists for the authenticated user.
Insert TaskCreates a new task in a given `tasklist id`, optionally as a subtask of an existing `task parent` or positioned after an existing `task previous` sibling, where both `task parent` and `task previous` must belong to the same `tasklist id` if specified.
List task listsFetches the authenticated user's task lists from google tasks; results may be paginated.
List TasksRetrieves tasks from a google tasks list; all date/time strings must be rfc3339 utc, and `showcompleted` must be true if `completedmin` or `completedmax` are specified.
Move TaskMoves the specified task to another position in the destination task list.
Patch TaskPartially updates an existing task (identified by `task id`) within a specific google task list (identified by `tasklist id`), modifying only the provided attributes from `taskinput` (e.

How to build Google Tasks MCP Agent with another framework

FAQ

What are the differences in Tool Router MCP and Google Tasks MCP?

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.

Can I use Tool Router MCP with ChatGPT?

Yes, you can. ChatGPT 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.

Can I manage the permissions and scopes for Google Tasks while using Tool Router?

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.

How safe is my data with Composio Tool Router?

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.
