List site-to-site VPN tunnels (IPsec, WireGuard, OpenVPN site-to-site) at a site. Returns: tunnel definitions per row (per-row schema not rendered in 10.5.43 docs — call to inspect). For roaming client VPN servers, see unifi_list_vpn_servers.
AI agents call unifi_list_vpn_tunnels to retrieve information from UniFi Network MCP Server 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 VPN tunnel configuration data from a UniFi site without modifying, executing, or deleting anything. While VPN tunnel information could be sensitive, the tool itself performs only information retrieval. Severity is low because listing configurations is non-destructive and does not directly grant access to network data—only metadata about tunnel definitions.
From the tool's definition Tool name contains 'list' and description states 'List site-to-site VPN tunnels' with 'Returns: tunnel definitions per row'. The verb 'list' and the return-only nature indicate a read operation with no side effects.

List site-to-site VPN tunnels (IPsec, WireGuard, OpenVPN site-to-site) at a site. Returns: tunnel definitions per row (per-row schema not rendered in 10.5.43 docs — call to inspect). For roaming client VPN servers, see unifi_list_vpn_servers. It is categorised as a Read tool in the UniFi Network MCP Server MCP Server, which means it retrieves data without modifying state.
Register the UniFi Network MCP Server MCP server in PolicyLayer and add a rule for unifi_list_vpn_tunnels: 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 MCP Server. Nothing to install.
unifi_list_vpn_tunnels 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 unifi_list_vpn_tunnels 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 unifi_list_vpn_tunnels. 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.
unifi_list_vpn_tunnels is provided by the UniFi Network MCP Server MCP server (owine/unifi-network-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
