List all defined limits
AI agents call vna_list_limits to retrieve information from Copper Mountain Vna without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates existing limit definitions from a Copper Mountain Vector Network Analyzer. It performs a non-destructive read operation that returns configuration information without modifying, executing, or deleting any data. The blast radius is minimal—an AI agent misusing this tool would only retrieve information it may not need, with no capability to harm hardware, calibration, or measurements.
From the tool's definition Tool name 'vna_list_limits' and description 'List all defined limits' indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
List all defined limits. It is categorised as a Read tool in the Copper Mountain Vna MCP Server, which means it retrieves data without modifying state.
Register the Copper Mountain Vna MCP server in PolicyLayer and add a rule for vna_list_limits: 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_list_limits 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 vna_list_limits 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_list_limits. 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_list_limits 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.
