How to integrate Google Tasks MCP with Antigravity

Antigravity IDE is Google's agentic IDE, built on a VS Code-style editor and powered by models like Gemini 3.5 Flash, Gemini 3.1 Pro, Opus 4.6, and more. It treats the AI agent as a first-class teammate, planning, coding, and validating work through an Agent Manager dashboard with deep browser connectivity.

In this guide, I will explain the easiest and most secure way to connect your Google Tasks account to Antigravity IDE via Composio Connect, so it can add a new task to your work list, list all tasks due this week, delete completed tasks from your shopping list, and more without ever putting your account credentials at risk.

Why use Composio?

Composio provides:

  • Access to 1,000+ managed apps from a single MCP endpoint. This makes it convenient for agents to run cross-app workflows.
  • Programmatic tool calling. Allows LLMs to write code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
  • Large tool response handling outside the LLM context. This minimizes context bloat from large tool responses.
  • Dynamic just-in-time access to thousands of tools across hundreds of apps. Composio loads the tools your agent needs, so LLMs are not overwhelmed by tools they do not need.

Connect Google Tasks to Antigravity

Antigravity does not ship with one-click custom MCP install links yet, so configuration goes through the IDE's raw config file. The process takes under a minute.

1. Open the MCP Config

Go to Antigravity Settings, open the Customizations tab, then click Open MCP Config to open mcp_config.json in the editor.

2. Get your API key

Go to the Composio Dashboard and copy your API key.

3. Add Composio to mcp_config.json

Paste the following configuration into the file:

bash
{
  "mcpServers": {
    "remote-composio": {
      "serverUrl": "https://connect.composio.dev/mcp",
      "headers": {
        "x-consumer-api-key": "your-composio-api-key"
      }
    }
  }
}

Note: Antigravity uses serverUrl, not url, for remote HTTP-based MCP servers. This differs from the url key used in Cursor and VS Code configs.

Save the file and click refresh in the Installed MCP Servers section.

Connect your Google Tasks account

Back in the Antigravity agent panel, ask the agent to connect to Google Tasks or give it any Google Tasks-related task.

For example, ask it 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 to Google Tasks.

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

Supported Tools & Triggers

Tools
Triggers
Batch Execute Google Tasks OperationsExecutes multiple Google Tasks API operations in a single HTTP batch request and returns structured per-item results.
Clear tasksPermanently and irreversibly clears all completed tasks from a specified Google Tasks list; this action is destructive, idempotent, and cannot be undone.
Create a task listCreates a new task list with the specified title and returns a tasklist_id.
Delete taskDeletes a specified task from a Google Tasks list.
Delete task listPermanently deletes an existing Google Task list, identified by `tasklist_id`, along with all its tasks; this operation is irreversible.
Get TaskRetrieve a specific Google Task.
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 All Tasks Across All ListsTool to list all tasks across all of the user's task lists with optional filters.
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 task list or to a different 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.
Patch task listUpdates the title of an existing Google Tasks task list.
Update Task (Full Replacement)Tool to fully replace an existing Google Task using PUT method.
Update Task ListUpdates the authenticated user's specified task list.

Conclusion

You have successfully connected Google Tasks to Antigravity using Composio Connect. Your agent can now use Google Tasks securely without exposing credentials in prompts or local scripts.

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 Antigravity?

Yes, you can. Antigravity 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.
