unblock_task · Keshro MCP: Risk & Policy

WHAT IT DOES

What unblock_task does on Keshro MCP

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

WHY IT NEEDS A POLICY

Why unblock_task needs a policy

Unblocking a task modifies task metadata/state reversibly (a blocked task can be blocked again), placing it in Write rather than Execute or Destructive. The empty description reduces confidence. Medium severity reflects potential workflow disruption if an agent unblocks critical tasks inappropriately, but the effect is reversible.

From the tool's definition Tool name 'unblock_task' indicates modification of task state; description is empty, limiting certainty. Sibling tools like 'block_task', 'complete_task', 'edit_task' suggest this server manages task workflow state reversibly.

Verdict

unblock_task Rate-limited

unblock_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.
