WHAT IT DOES

What reopen_plan does on TestRail MCP Server

WHY IT NEEDS A POLICY

Why reopen_plan needs a policy

This tool modifies existing data (test plan status) in a reversible manner, characteristic of Write operations. It does not execute external code, delete data permanently, or involve financial transactions. The moderate severity reflects that reopening a test plan could affect test workflows and reporting if misused by an AI agent, but the change is recoverable (can be closed again).

From the tool's definition Tool name 'reopen_plan' and description 'Reopen test plan' indicate modification of test plan state from closed to reopened, a reversible state change operation.
