clean_admin_temp · Mealie MCP Server MCP: Risk & Policy

WHAT IT DOES

What clean_admin_temp does on Mealie MCP Server

AI agents invoke clean_admin_temp to trigger actions in Mealie 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.

WHY IT NEEDS A POLICY

Why clean_admin_temp needs a policy

This tool executes a system-level operation (admin cleanup) that performs side effects on the server's filesystem. While not permanently destructive in the sense of deleting user data, it irreversibly removes files and cannot be easily undone if the wrong temporary files are affected.

From the tool's definition 'Run admin temporary file cleanup' indicates execution of a cleanup/maintenance operation that modifies the filesystem state by deleting temporary files.
