서비스 상태 확인
AI agents call health to retrieve information from Guardian News MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Health/status checks are read-only operations that query the current state of a service. They have no side effects, cannot modify data, and pose minimal security risk. This fits the 'Read' category as a simple information retrieval operation.
From the tool's definition Tool name 'health' and description '서비스 상태 확인' (service status check in Korean) indicate a status/health check endpoint that retrieves service operational state without modifying data or triggering side effects.

Register the Guardian News MCP Server MCP server in PolicyLayer and add a rule for health: 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 Guardian News MCP Server. Nothing to install.
health 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 health 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 health. 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.
health is provided by the Guardian News MCP Server MCP server (seonaru/guardian-news-analyst). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
