WHAT IT DOES

What wp_activate_theme does on Wordpress

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

RISK

Why wp_activate_theme is rated Medium

Activating a theme modifies the WordPress site's appearance and functionality by changing which theme is currently active. This is a write operation because it changes persisted configuration state. However, it is reversible (another theme can be activated afterward) so it does not qualify as Destructive.

From the tool's definition Tool name 'wp_activate_theme' with description 'Activate a theme (switch themes)' — the verb 'activate' indicates modification of WordPress configuration state by changing the active theme, which is a reversible write operation.
