[Licensing] List all installed licenses.
AI agents call licensing_list_licenses 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 queries and returns licensing information without side effects. It performs a read-only operation that retrieves existing data about installed licenses. There is no capability to modify, delete, execute operations, or commit financial transactions.
From the tool's definition Tool name contains 'list' and description states 'List all installed licenses' – a straightforward data retrieval operation with no modification, deletion, or execution of commands.

Register the CyPerf MCP Server MCP server in PolicyLayer and add a rule for licensing_list_licenses: 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.
licensing_list_licenses 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 licensing_list_licenses 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 licensing_list_licenses. 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.
