AI agents call samr_get_standard to retrieve information from GBMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The naming pattern and server context indicate this tool retrieves or queries standard documents/metadata without modification. No evidence of destructive, execute, or financial operations. The empty description lowers confidence slightly, but the sibling tools and server purpose strongly suggest read-only retrieval semantics.
From the tool's definition Tool name 'samr_get_standard' suggests retrieval of standard metadata (parallel to sibling 'cfsa_get_standard' and 'doc88_get_document').

Yes. Add a rate_limit block to the samr_get_standard 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 samr_get_standard. 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.
