List Central NAC Named MPSK registrations (bounded by default).
AI agents call list_mpsk_registrations to retrieve information from API-Central without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and lists existing MPSK (Multi-Pre-Shared Key) NAC registrations from HPE Aruba Central. The verb 'list' is explicitly a read-only operation that queries data without creating, modifying, or deleting anything. The qualifier '(bounded by default)' indicates the results are constrained, further reducing any potential impact.
From the tool's definition Tool name 'list_mpsk_registrations' and description 'List Central NAC Named MPSK registrations' indicate a retrieval/query operation with no modification or side effects.

List Central NAC Named MPSK registrations (bounded by default). It is categorised as a Read tool in the API-Central MCP Server, which means it retrieves data without modifying state.
Register the API-Central MCP server in PolicyLayer and add a rule for list_mpsk_registrations: 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 API-Central. Nothing to install.
list_mpsk_registrations 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 list_mpsk_registrations 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 list_mpsk_registrations. 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.
list_mpsk_registrations is provided by the API-Central MCP server (secure-ssid/centralmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
