nec2_create_dipole · Mcp Nec2 Antenna MCP: Risk & Policy

WHAT IT DOES

What nec2_create_dipole does on Mcp Nec2 Antenna

AI agents use nec2_create_dipole to create or update resources in Mcp Nec2 Antenna — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Nec2 Antenna environment.

WHY IT NEEDS A POLICY

Why nec2_create_dipole needs a policy

This tool creates a new antenna design object (reversible data creation) without executing simulations, deleting data, or moving resources. The created antenna configuration can be modified or deleted later. While it prepares for Execute-category simulation, the tool itself only performs Write operations.

From the tool's definition Tool description states "Create a half-wave dipole antenna. Returns antenna ID for simulation." The verb "Create" indicates data creation; the tool generates and stores a new antenna configuration artifact.

Verdict

nec2_create_dipole Rate-limited

nec2_create_dipole stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about nec2_create_dipole

What does the nec2_create_dipole tool do? +

Create a half-wave dipole antenna. Returns antenna ID for simulation. 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_dipole? +

Register the Mcp Nec2 Antenna MCP server in PolicyLayer and add a rule for nec2_create_dipole: 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_dipole? +

nec2_create_dipole is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit nec2_create_dipole? +

Yes. Add a rate_limit block to the nec2_create_dipole 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_dipole completely? +

Set action: deny in the PolicyLayer policy for nec2_create_dipole. 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_dipole? +

nec2_create_dipole 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.
