WHY IT NEEDS A POLICY

Why nec2_create_inverted_v needs a policy

This tool creates and stores a new antenna design configuration within the NEC2 simulator. While it modifies the simulation state by adding a new antenna model, the change is reversible (the antenna design can be replaced, updated, or deleted), and there are no permanent system changes, irreversible deletions, code execution, financial impacts, or external side effects.

From the tool's definition Tool name 'nec2_create_inverted_v' with description 'Create an inverted-V dipole antenna' indicates creation of a new antenna design object.

FAQ

Questions about nec2_create_inverted_v

What does the nec2_create_inverted_v tool do? +

Create an inverted-V dipole antenna (requires only one support). It is categorised as a Write tool in the Mcp Nec2 Antenna MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on nec2_create_inverted_v? +

Register the Mcp Nec2 Antenna MCP server in PolicyLayer and add a rule for nec2_create_inverted_v: 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 Mcp Nec2 Antenna. Nothing to install.

What risk level is nec2_create_inverted_v? +

nec2_create_inverted_v is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit nec2_create_inverted_v? +

Yes. Add a rate_limit block to the nec2_create_inverted_v 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.

How do I block nec2_create_inverted_v completely? +

Set action: deny in the PolicyLayer policy for nec2_create_inverted_v. 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.

What MCP server provides nec2_create_inverted_v? +

nec2_create_inverted_v is provided by the Mcp Nec2 Antenna MCP server (rfingadam/mcp-nec2-antenna). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
