獲取系統基本信息（OS、CPU、內存等）
AI agents call get_system_info to retrieve information from Node Js MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns system metadata about the operating system, CPU, and memory. It performs no side effects, does not modify state, and does not execute code or commands. It is a straightforward read operation that retrieves static system information.
From the tool's definition Tool name 'get_system_info' and description 'retrieve system basic information (OS, CPU, memory, etc.)' indicate data retrieval with no modification or execution of operations.

獲取系統基本信息（OS、CPU、內存等）. It is categorised as a Read tool in the Node Js MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Node Js MCP Server MCP server in PolicyLayer and add a rule for get_system_info: 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 Node Js MCP Server. Nothing to install.
get_system_info 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_system_info 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_system_info. 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_system_info is provided by the Node Js MCP Server MCP server (weiweicode/20250923mcptest). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
