세션 상태 확인
AI agents call check_session to retrieve information from PerfDog to Tableau MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads/queries the current session status to verify authentication or connection state. It has no side effects, does not modify data, execute code, or perform destructive operations. It is a simple status check typical of Read-category tools. Severity is low because misuse cannot cause harm beyond potentially exposing session metadata or connection state.

Yes. Add a rate_limit block to the check_session 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 check_session. 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.
check_session is provided by the PerfDog to Tableau MCP Server MCP server (kimjeonghyun225-cpu/perfdog_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
