prioritize_task · Todos MCP: Risk & Policy

WHAT IT DOES

What prioritize_task does on Todos

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

WHY IT NEEDS A POLICY

Why prioritize_task needs a policy

Prioritizing a task modifies task metadata reversibly—the priority can be changed again or reverted. This is a standard write operation with low blast radius since it does not delete data, execute arbitrary code, or create financial obligations. The impact is limited to reordering task execution sequence, which is a normal task management function.

From the tool's definition Tool name 'prioritize_task' and description 'Set a task' indicate modification of task properties (priority level). The verb 'Set' and context of a task management system confirm this is a write operation that modifies existing data.

Verdict

prioritize_task Rate-limited

prioritize_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.
