Get the list of players currently on the Minecraft server, as well as the maximum player count and whether the whitelist is enabled.
AI agents call get_players to retrieve information from OPanel MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves server state information (current players, max player count, whitelist status) without creating, modifying, deleting, or executing operations. It is purely a query operation with read-only access to non-sensitive server metadata. The low severity reflects minimal blast radius if an AI agent calls this tool—it gathers information only.
From the tool's definition Tool name 'get_players' and description 'Get the list of players currently on the Minecraft server' indicate data retrieval with no modification or side effects.
Attacks that exploit this kind of access
Get the list of players currently on the Minecraft server, as well as the maximum player count and whether the whitelist is enabled. It is categorised as a Read tool in the OPanel MCP MCP Server, which means it retrieves data without modifying state.
Register the OPanel MCP server in PolicyLayer and add a rule for get_players: 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 OPanel MCP. Nothing to install.
get_players 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 get_players 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 get_players. 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.
get_players is provided by the OPanel MCP server (opanel-mc/opanel-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
