close_plan · TestRail MCP Server MCP: Risk & Policy

WHAT IT DOES

What close_plan does on TestRail MCP Server

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

WHY IT NEEDS A POLICY

Why close_plan needs a policy

Closing a plan changes its state reversibly—it can typically be reopened or the change undone through other operations. This is a write operation (modifying data) rather than destructive (permanent deletion). The blast radius is medium because it affects test plan workflow and visibility for team members, but the action remains reversible.

From the tool's definition Tool name 'close_plan' and description 'Close a test plan' indicate a state change operation on a TestRail plan resource. This modifies plan status/metadata but does not delete or destroy the plan irreversibly.

close_plan Rate-limited
