postpone_task · RTM MCP Server MCP: Risk & Policy

WHAT IT DOES

What postpone_task does on RTM MCP Server

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

WHY IT NEEDS A POLICY

Why postpone_task needs a policy

This tool modifies task metadata (due date) reversibly without deleting data or executing arbitrary operations. It falls under Write category because it updates an existing resource. Severity is medium because mistaken postponements could disrupt task management workflows, but the change is easily undone by adjusting the date forward again.

From the tool's definition Tool description states it 'Postpone a task (moves due date by one day)' - this modifies the due date attribute of a task, which is a reversible change to task data. The operation is a temporal adjustment rather than deletion or execution of external commands.

postpone_task Rate-limited

postpone_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.
