Health check endpoint for monitoring.
AI agents call health_check to retrieve information from Reddit MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Health check endpoints are standard monitoring tools that query service state and availability. They retrieve status information with no side effects, no code execution, no data modification, and no destructive actions. This is a benign Read operation. Severity is low because even if called excessively or at unexpected times, it only returns status and poses minimal risk to the system or data.
From the tool's definition Tool named 'health_check' with description 'Health check endpoint for monitoring.' — a diagnostic read-only operation that returns service status without modifying, executing, or deleting anything.

Register the Reddit MCP Server MCP server in PolicyLayer and add a rule for health_check: 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 Reddit MCP Server. Nothing to install.
health_check 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_check 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_check. 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_check is provided by the Reddit MCP Server MCP server (padak/apify-actor-reddit-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
