Reset VNA to default state (*RST)
AI agents call vna_reset to permanently remove resources in Copper Mountain Vna — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
A factory/default reset (*RST) irreversibly clears all current configuration, calibration data, sweep settings, and measurements on the VNA. This cannot be undone — all active state is lost. This maps to Destructive. Severity is high because it would wipe calibration and measurement setups that may have taken significant time and effort to configure.

Attacks that exploit this kind of access
Reset VNA to default state (*RST). It is categorised as a Destructive tool in the Copper Mountain Vna MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Copper Mountain Vna MCP server in PolicyLayer and add a rule for vna_reset: 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 Copper Mountain Vna. Nothing to install.
vna_reset is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the vna_reset 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 vna_reset. 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.
vna_reset is provided by the Copper Mountain Vna MCP server (rfingadam/copper-mountain-vna-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
