Retrieve UniFi devices (switches, APs, gateways) for a site
AI agents call get_devices 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 retrieves device information (switches, APs, gateways) from a UniFi network controller without creating, modifying, or deleting any data. It produces no side effects and presents minimal risk even if queried arbitrarily. Severity is low because the information retrieved is operational metadata about network infrastructure with limited sensitivity in most contexts.
From the tool's definition Tool name 'get_devices' and description 'Retrieve UniFi devices' indicate data retrieval with no modification. Server is explicitly described as 'Read-only MCP server'.
Attacks that exploit this kind of access
Retrieve UniFi devices (switches, APs, gateways) for a site. 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_devices: 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_devices 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_devices 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_devices. 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_devices 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.
