WHAT IT DOES

What alm_update_defect does on HP ALM MCP Server

WHY IT NEEDS A POLICY

Why alm_update_defect needs a policy

Updating a defect modifies QA workflow state and tracking data. This is reversible (Write category) rather than destructive or read-only. Severity is medium because defect modifications could affect test tracking and reporting, but individual updates are unlikely to cause critical system failures. Confidence is slightly reduced because the tool description is empty, requiring inference from name and context.

From the tool's definition Tool name is 'alm_update_defect' indicating modification of defect records in HP ALM. Sibling tools show this server manages test cases, defects, and requirements. The 'update' verb signals reversible modification rather than deletion.
