[Configurations] List configuration categories.
AI agents call configs_categories to retrieve information from CyPerf MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or lists metadata about configuration categories without creating, modifying, deleting, or executing any operations. It is a read-only query operation with minimal blast radius if misused by an AI agent—an assistant cannot cause harm by listing categories.

[Configurations] List configuration categories. It is categorised as a Read tool in the CyPerf MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CyPerf MCP Server MCP server in PolicyLayer and add a rule for configs_categories: 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.
configs_categories 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 configs_categories 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 configs_categories. 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.
configs_categories 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.
