reassign_task · Todos MCP: Risk & Policy

WHAT IT DOES

What reassign_task does on Todos

AI agents use reassign_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 reassign_task needs a policy

Reassigning a task modifies the task's assignment metadata, which is a reversible write operation. It does not delete data or execute code, but it does change ownership/routing of work, which could disrupt ongoing agent workflows if misused.

Verdict

reassign_task Rate-limited

reassign_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.
