WHAT IT DOES

What jira_edit_comment does on Jira MCP Server

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

WHY IT NEEDS A POLICY

Why jira_edit_comment needs a policy

This tool creates or modifies data reversibly by editing comment text on Jira tickets. The change can be undone (previous versions retained, comment can be edited again), making it a Write operation rather than Destructive. The severity is medium because misuse could modify important project documentation or communications, but the impact is limited to comment metadata and can be corrected.

From the tool's definition Tool name 'jira_edit_comment' and description 'Edit an existing comment on a Jira ticket. Replaces the comment text' explicitly indicates modification of existing data.

Questions about jira_edit_comment

What does the jira_edit_comment tool do? +

Edit an existing comment on a Jira ticket. Replaces the comment text.
