获取当前系统的用户信息
AI agents call getUserInfo 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 queries and retrieves user information from the system. It performs a read-only operation that does not create, modify, delete, or execute any actions. However, severity is elevated to 'medium' due to the sensitivity of user information disclosure, which could reveal account names, UIDs, group memberships, and other identity data useful for reconnaissance or privilege escalation planning by a malicious…

获取当前系统的用户信息. 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 getUserInfo: 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.
getUserInfo 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 getUserInfo 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 getUserInfo. 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.
getUserInfo 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.
