Add a private comment/note to a ticket (not visible to requestor).
AI agents use add_ticket_comment_tool to create or update resources in MCP Request-tracker — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Request-tracker environment.
This tool creates new comment data (reversible write operation) on a ticket. While it modifies state, it does not delete data, execute code, move money, or produce irreversible changes. The scope is limited to adding internal notes to a single ticket. The private nature (not visible to requestor) slightly reduces blast radius but does not change the category from Write.
From the tool's definition Tool description states 'Add a private comment/note to a ticket', which is a create/modify operation that adds data to an existing ticket.
