WHAT IT DOES

What mcp_install_theme does on Wordpress

AI agents use mcp_install_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 mcp_install_theme is rated Medium

This tool installs (creates) a new theme in the WordPress environment. While installation is technically reversible (themes can be uninstalled), it modifies the site's state, adds executable code to the system, and could introduce vulnerabilities or alter site behavior. This is a Write operation rather than Execute because the tool itself doesn't run arbitrary code—it fetches and installs a pre-packaged theme.

From the tool's definition Tool name 'mcp_install_theme' and description 'Install a theme from WordPress.org by slug' indicate creation/installation of a new theme resource in WordPress.
