Find the nearest entity of a specific type
AI agents call find-entity to retrieve information from Minecraft MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the game world to locate entities (mobs, players, etc.) but does not create, modify, delete, execute commands, or move money. It is a pure information retrieval operation with no side effects on game state. The low severity reflects that merely detecting entity locations poses minimal risk of unintended harm.
From the tool's definition Tool is named 'find-entity' and described as 'Find the nearest entity of a specific type'. The verb 'find' indicates a search/query operation that retrieves information about game state without modifying it.
Attacks that exploit this kind of access
Find the nearest entity of a specific type. It is categorised as a Read tool in the Minecraft MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Minecraft MCP Server MCP server in PolicyLayer and add a rule for find-entity: 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 MCP Server. Nothing to install.
find-entity is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the find-entity 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.
Set action: deny in the PolicyLayer policy for find-entity. 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.
find-entity is provided by the Minecraft MCP Server MCP server (zeeweebee/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
