create-task · Google Tasks MCP: Risk & Policy

WHAT IT DOES

What create-task does on Google Tasks

AI agents use create-task to create or update resources in Google Tasks — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Google Tasks environment.

WHY IT NEEDS A POLICY

Why create-task needs a policy

The tool creates a new task, which is reversible (tasks can be deleted via the sibling delete-task tool). This is a standard write operation with minimal blast radius—creating a task does not modify existing data, execute code, delete anything, or move money. Severity is low because the impact is limited to task management data, and any unintended tasks created can be easily removed.

From the tool's definition Tool name is 'create-task' and description states 'Create a new task.' This is a write operation that creates new data in Google Tasks.

Verdict

create-task Rate-limited

create-task stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
