WHAT IT DOES

What create_test_set does on Mxray

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

WHY IT NEEDS A POLICY

Why create_test_set needs a policy

This tool creates a new test set, which is a reversible write operation. It adds data to the Jira Cloud system but does not execute arbitrary code, delete data irreversibly, or move financial resources. The severity is medium because creating test sets in a test management system could affect test execution workflows, but the impact is limited to test metadata and is easily reversible.

From the tool's definition Tool name is 'create_test_set' and description states 'Create a new test set in Jira.' The verb 'create' and 'new' indicate data creation.
