What add_jira_comment does on GalaxyMCP Server

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

WHY IT NEEDS A POLICY

Why add_jira_comment needs a policy

Adding a comment modifies ticket state by creating new content, making it a Write operation. It is not Read (does not merely retrieve data), not Execute (does not run arbitrary code or external operations based on comment content), not Destructive (comments are not irreversibly deleted by this action), and not Financial.

From the tool's definition Tool description: 'Add a comment to an existing JIRA ticket' — this creates/appends new data (a comment) to an existing JIRA ticket, which is reversible (comments can be deleted or edited).
