获取当前设备的 IPv4 信息
AI agents call getIpv4Info to retrieve information from Current operating environment without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves IPv4 network information from the operating environment. It is a passive query operation that reads and returns configuration data (IP addresses, network details) without modifying system state, executing commands, or performing destructive actions. Severity is low because IP information disclosure alone has limited direct impact—it is informational only.
From the tool's definition Tool name 'getIpv4Info' and description '获取当前设备的 IPv4 信息' (Get current device's IPv4 information) indicate retrieval of network configuration data without modification or side effects.

获取当前设备的 IPv4 信息. It is categorised as a Read tool in the Current operating environment MCP Server, which means it retrieves data without modifying state.
Register the Current operating environment MCP server in PolicyLayer and add a rule for getIpv4Info: 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 Current operating environment. Nothing to install.
getIpv4Info 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 getIpv4Info 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 getIpv4Info. 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.
getIpv4Info is provided by the Current operating environment MCP server (jackxuyi/env-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
