close-task · Todoist MCP: Risk & Policy

WHAT IT DOES

What close-task does on Todoist MCP

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

WHY IT NEEDS A POLICY

Why close-task needs a policy

Closing a task is a write operation that updates task state. It is reversible (tasks can be reopened), so it does not qualify as Destructive. The severity is medium because an AI agent misusing this could mark many tasks as complete, disrupting productivity workflows, but this can be undone by reopening tasks.

From the tool's definition Tool description states 'Close (complete) a task in Todoist' — this modifies task state from open to closed/completed, a reversible action that changes data without destruction.

Verdict

close-task Rate-limited

close-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.
