wpdev_fs_delete

THE RISK

Critical Risk

This tool irreversibly deletes files or folders, which is the defining characteristic of the Destructive category. While the tool includes a safety restriction (only paths within sitePath), the core functionality remains data destruction. The high severity reflects that an AI agent could accidentally delete critical WordPress configuration files, themes, plugins, or content.

From the tool's definition Tool name contains 'delete' and description explicitly states 'Delete a file or folder'. The operation is irreversible and removes data permanently.

HOW TO CONTROL WPDEV_FS_DELETE

PolicyLayer is an MCP gateway — it sits between your AI agents and WordPress Developer MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for wpdev_fs_delete:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "wpdev_fs_delete"
  ]
}

wpdev_fs_delete disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register WordPress Developer MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
