AI agents call health to retrieve information from Korean Law MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Health check tools are read-only operations that query system status. They have no side effects, do not modify data, execute code, delete data, or involve financial transactions. The blast radius of misuse is minimal—an agent could only waste API calls or infer service availability, posing negligible security risk.
From the tool's definition Tool name 'health' and description '서비스 상태 확인' (service status check) indicate a diagnostic endpoint that retrieves service health information without modifying or executing operations.
Documented attack patterns abuse exactly the kind of access health gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Korean Law MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for health:
{
"version": "1",
"default": "deny",
"tools": {
"health": {}
}
}health is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

서비스 상태 확인. It is categorised as a Read tool in the Korean Law MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Korean Law 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 Korean Law 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 Korean Law MCP Server MCP server (seonaru/korean-law-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
