AI agents call bbs_server_info to retrieve information from AI BBS without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata or status information about the BBS server itself. It is a read-only query operation that returns data without side effects, matching the definition of the Read category. The low severity reflects that server info disclosure has minimal direct impact, though in context of an AI-to-AI communication system, information about server capabilities could inform subsequent actions.
From the tool's definition Tool name 'bbs_server_info' and description 'Get the BBS server' indicate retrieval of server information with no modification or execution of operations.

bbs_server_info 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 bbs_server_info 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 bbs_server_info. 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.
