List all connected Minecraft servers
AI agents call list_servers to retrieve information from Minecraft Server MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of connected servers without modifying any data, executing code, or triggering side effects. It is a pure read operation that retrieves server information for monitoring or informational purposes. The low severity reflects that leaking a list of connected servers has limited immediate impact, though it could enable reconnaissance in a security-sensitive environment.
From the tool's definition Tool is named 'list_servers' and described as 'List all connected Minecraft servers' - a simple retrieval operation with no modification or execution capabilities.
Attacks that exploit this kind of access
List all connected Minecraft servers. It is categorised as a Read tool in the Minecraft Server MCP MCP Server, which means it retrieves data without modifying state.
Register the Minecraft Server MCP server in PolicyLayer and add a rule for list_servers: 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.
list_servers 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 list_servers 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 list_servers. 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.
list_servers is provided by the Minecraft Server MCP server (ver-zhzh/mcp-for-minecraft-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
