Retrieve UniFi controller and site sysinfo
AI agents call get_sysinfo to retrieve information from Unifi Network 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 system information about the UniFi controller and sites without any ability to modify, delete, or execute operations. It is purely informational (Read category). Severity is low because sysinfo disclosure has minimal blast radius—it provides operational details but not sensitive credentials or network data that would enable further attacks.
From the tool's definition Tool description states 'Retrieve UniFi controller and site sysinfo' and the server is explicitly described as 'Read-only MCP server'. The tool retrieves system information with no modification capability.
Attacks that exploit this kind of access
Retrieve UniFi controller and site sysinfo. It is categorised as a Read tool in the Unifi Network MCP Server, which means it retrieves data without modifying state.
Register the Unifi Network MCP server in PolicyLayer and add a rule for get_sysinfo: 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 Unifi Network. Nothing to install.
get_sysinfo 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_sysinfo 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_sysinfo. 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_sysinfo is provided by the Unifi Network MCP server (unifi-network-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
