AI agents call getNearbyPlayers to retrieve information from MCP Minecraft Remote without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about player locations in the game world. It performs a read-only query with no side effects—no data is modified, deleted, or executed. While the parent server enables control of Minecraft gameplay (which includes Execute-category tools like attackEntity and digBlock), this specific tool is purely informational.
From the tool's definition Tool name 'getNearbyPlayers' and description 'Get a list of players nearby' indicate a query operation that retrieves data about nearby players without modifying game state or triggering actions.
Documented attack patterns abuse exactly the kind of access getNearbyPlayers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Minecraft Remote, and nothing reaches the server without passing your rules. This is the rule we recommend for getNearbyPlayers:
{
"version": "1",
"default": "deny",
"tools": {
"getNearbyPlayers": {}
}
}getNearbyPlayers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
