teleport · Minecraft Server MCP: Risk & Policy

WHAT IT DOES

What teleport does on Minecraft Server MCP

AI agents invoke teleport to trigger actions in Minecraft Server MCP. 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 teleport needs a policy

Teleporting a player or entity triggers an external operation (movement in the game world) with real effects on gameplay state. It is not purely reading data, and while it can be undone by teleporting back, it is an active operation with side effects. It fits Execute as it moves entities based on arguments, with medium severity since misuse could disrupt players but is generally reversible.

Verdict

teleport Rate-limited

teleport 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Minecraft Server MCP, so you can run agents against it safely.

FAQ

Questions about teleport

What does the teleport tool do? +

Teleport a player or entity to coordinates or another entity. It is categorised as a Execute tool in the Minecraft Server MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on teleport? +

Register the Minecraft Server MCP server in PolicyLayer and add a rule for teleport: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Minecraft Server MCP. Nothing to install.

What risk level is teleport? +

teleport is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit teleport? +

Yes. Add a rate_limit block to the teleport rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block teleport completely? +

Set action: deny in the PolicyLayer policy for teleport. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides teleport? +

teleport is provided by the Minecraft Server MCP server (tamo2918/minecraft-server-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
