## Why add_user_to_group is rated Medium

This tool creates or modifies data (group membership) in a reversible manner. A user can be removed from a group if needed. While it affects access control and permissions (warranting medium severity), it is not destructive, financial, or code execution. The blast radius is moderate: an agent could add unauthorized users to sensitive groups, but the action is undoable.

From the tool's own definition: "Tool name is 'add_user_to_group' and description states it will 'Add a user to a group' — a create/modify operation that changes group membership."

## Use case

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