AI agents invoke wordpress_execute_shortcode to trigger actions in WordPress MCP Server. 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.
Shortcode execution in WordPress is inherently an Execute action—it triggers callbacks and PHP logic. The empty description is uninformative, but the tool name and server context (site-wide control) make the intent clear. High severity because malicious shortcodes can read/write files, exfiltrate data, or compromise the site; blast radius depends on what the shortcode does but is typically broad.
From the tool's definition Tool name 'wordpress_execute_shortcode' explicitly indicates execution of shortcode logic. Shortcodes in WordPress are code execution mechanisms that run arbitrary PHP/callback functions.

"window": "minute",
"max": 10,
"scope": "grant"
}
]
