AI agents call get_gpo_links to retrieve information from LegacyMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Although the description is empty, the naming convention and context within a read-only AD assessment server indicate this is a Read operation.

Yes. Add a rate_limit block to the get_gpo_links 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.
