connect · Minecraft Server MCP: Risk & Policy

WHAT IT DOES

What connect does on Minecraft Server MCP

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

WHY IT NEEDS A POLICY

Why connect needs a policy

Establishing a connection to a server is a Write/state-change operation — it creates a new session or authenticated link. It is not purely reading data, nor is it destructive or financial. Misuse could allow an AI to connect to unintended servers and then leverage other tools (send_command, etc.) for further impact, giving it medium severity.

Verdict

connect Rate-limited

connect 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.
