pardon_player · OPanel MCP: Risk & Policy

WHAT IT DOES

What pardon_player does on OPanel MCP

AI agents use pardon_player to create or update resources in OPanel MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your OPanel MCP environment.

WHY IT NEEDS A POLICY

Why pardon_player needs a policy

This tool modifies the server's ban list by removing a player from it. It is reversible (the player can be re-banned), so it falls under Write rather than Destructive. Misuse could allow previously banned (e.g., abusive or cheating) players back onto the server, giving it a medium severity.

Verdict

pardon_player Rate-limited

pardon_player 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.
