certs_generate · CyPerf MCP Server MCP: Risk & Policy

WHAT IT DOES

What certs_generate does on CyPerf MCP Server

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

WHY IT NEEDS A POLICY

Why certs_generate needs a policy

Generating certificates creates new data assets that are reversibly modifiable (certificates can be regenerated, revoked, or replaced). This is a Write operation rather than Execute because it creates a specific artifact type through a bounded operation, not arbitrary code execution.

From the tool's definition Tool name 'certs_generate' and description 'Generate a new certificate' indicate creation of new cryptographic certificate artifacts.

Verdict

certs_generate Rate-limited

certs_generate 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 certs_generate

What does the certs_generate tool do? +

[Certificates] Generate a new certificate. It is categorised as a Write tool in the CyPerf MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on certs_generate? +

Register the CyPerf MCP Server MCP server in PolicyLayer and add a rule for certs_generate: 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 CyPerf MCP Server. Nothing to install.

What risk level is certs_generate? +

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

Can I rate-limit certs_generate? +

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

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

certs_generate is provided by the CyPerf MCP Server MCP server (keysight/cyperf-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
