List all sites available on a UniFi controller target
AI agents call list_sites 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 returns information about available sites without creating, modifying, deleting, or executing any operations. It is a straightforward data retrieval function consistent with the Read category. The read-only nature of the server and the lack of any side effects makes this low severity.
From the tool's definition Tool name 'list_sites' and description 'List all sites available on a UniFi controller target' indicate a retrieval operation with no modification capability. Server is explicitly described as 'Read-only MCP server'.
Attacks that exploit this kind of access
List all sites available on a UniFi controller target. 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 list_sites: 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.
list_sites 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 list_sites 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 list_sites. 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.
list_sites 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.
