wp_theme_activate · Wp Cli MCP: Risk & Policy

WHAT IT DOES

What wp_theme_activate does on Wp Cli

AI agents invoke wp_theme_activate to trigger actions in Wp Cli. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why wp_theme_activate needs a policy

Activating a theme is a site-wide operation that changes the public-facing appearance and functionality of the WordPress site for all users. It triggers WordPress action hooks (switch_theme, after_switch_theme) that can execute arbitrary code, and can break site functionality if an incompatible theme is activated.

From the tool's definition 'Activate a theme' — changes the active theme for the entire WordPress site, triggering theme switch hooks and affecting all site visitors immediately
