openems_create_microstrip · Mcp Openems MCP: Risk & Policy

WHAT IT DOES

What openems_create_microstrip does on Mcp Openems

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

WHY IT NEEDS A POLICY

Why openems_create_microstrip needs a policy

This tool creates design artifacts (microstrip geometry) within an electromagnetic simulation context. The output is reversible design data that can be modified, deleted, or replaced. While it performs calculations and generates geometry, it does not execute external commands, delete data irreversibly, move money, or trigger uncontrolled side effects.

From the tool's definition Tool 'generates 2-port geometry for S-parameter extraction' and 'Design a microstrip trace' — creates or modifies electromagnetic design data (geometry/trace definitions) that can be edited or discarded.

Verdict

openems_create_microstrip Rate-limited

openems_create_microstrip 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 openems_create_microstrip

What does the openems_create_microstrip tool do? +

Design a microstrip trace and calculate characteristic impedance using Hammerstad formula. Generates 2-port geometry for S-parameter extraction. It is categorised as a Write tool in the Mcp Openems MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on openems_create_microstrip? +

Register the Mcp Openems MCP server in PolicyLayer and add a rule for openems_create_microstrip: 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 Openems. Nothing to install.

What risk level is openems_create_microstrip? +

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

Can I rate-limit openems_create_microstrip? +

Yes. Add a rate_limit block to the openems_create_microstrip 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 openems_create_microstrip completely? +

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

openems_create_microstrip is provided by the Mcp Openems MCP server (rfingadam/mcp-openems). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
