AI agents call get_device to retrieve information from Unifi without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns data about a network device (details, uplink topology) with no side effects. It is a read-only information retrieval operation, comparable to 'get' or 'fetch' operations. The severity is low because reading device metadata poses minimal risk even if misused by an agent.
From the tool's definition Tool name is 'get_device' and description indicates it 'Get full details for a single adopted device including uplink topology' — this retrieves information without modifying or executing actions.
Attacks that exploit this kind of access
Get full details for a single adopted device including uplink topology,. It is categorised as a Read tool in the Unifi MCP Server, which means it retrieves data without modifying state.
Register the Unifi MCP server in PolicyLayer and add a rule for get_device: 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. Nothing to install.
get_device 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_device 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_device. 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_device is provided by the Unifi MCP server (pproenca/unifi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
