mc_deop · Mc Rcon MCP: Risk & Policy

WHAT IT DOES

What mc_deop does on Mc Rcon

WHY IT NEEDS A POLICY

Why mc_deop needs a policy

Removing operator (admin) privileges from a player is a reversible modification to the server's operator list. The action can be undone by re-granting op status with mc_op, making it Write rather than Destructive. However, misuse could disrupt server administration by removing legitimate admins, giving it medium severity.

Verdict

mc_deop Rate-limited

mc_deop stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
