add_comment · AI-Powered Jira MCP Server MCP: Risk & Policy

WHAT IT DOES

What add_comment does on AI-Powered Jira MCP Server

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

WHY IT NEEDS A POLICY

Why add_comment needs a policy

Adding a comment modifies issue data but does not delete it, make it irreversible, or cause financial impact. It is a Write operation because it creates or modifies data reversibly.

From the tool's definition Tool description states 'Add a comment to an existing Jira issue.' Comments are modifications to issue data that are reversible (comments can be edited or deleted).
