jump · Minecraft MCP Server MCP: Risk & Policy

WHAT IT DOES

What jump does on Minecraft MCP Server

AI agents invoke jump to trigger actions in Minecraft 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 jump needs a policy

Jumping is an in-game action that executes a physical operation controlling the Minecraft character. It has minimal blast radius as it only causes the bot to jump momentarily with no persistent or destructive effects, but it is still an execution of an external action rather than a simple read.

From the tool's definition 'Make the bot jump' - triggers an external operation (physical action) in the Minecraft world

Verdict

jump Rate-limited

jump stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
