AI agents call net_check_connectivity to retrieve information from LuzzyTool without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only network diagnostic — it checks TCP connectivity and measures latency. It does not modify any data, execute commands, or have side effects beyond sending probe packets. Equivalent to a ping/port-check utility.
From the tool's definition 检测到指定主机端口的 TCP 连通性，返回是否可达和延迟 (detects TCP connectivity to a specified host port, returns reachability and latency)

【网络诊断】检测到指定主机端口的 TCP 连通性，返回是否可达和延迟。. It is categorised as a Read tool in the LuzzyTool MCP Server, which means it retrieves data without modifying state.
Register the LuzzyTool MCP server in PolicyLayer and add a rule for net_check_connectivity: 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 LuzzyTool. Nothing to install.
net_check_connectivity 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 net_check_connectivity 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 net_check_connectivity. 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.
net_check_connectivity is provided by the LuzzyTool MCP server (luzzymeow/luzzytool). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
