unpin_task · Filevine MCP: Risk & Policy

WHAT IT DOES

What unpin_task does on Filevine

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

WHY IT NEEDS A POLICY

Why unpin_task needs a policy

Unpinning a task changes its display/priority state but does not delete it. This is a reversible modification (the task can be re-pinned), so it falls under Write. Severity is low since it only affects task visibility/pinning status, not the task's core data or any sensitive legal information.

From the tool's definition 'Unpin a task' — unpinning modifies the pinned state of a task, which is a reversible change

Verdict

unpin_task Rate-limited

unpin_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.
