Check app server health and response time. Makes HTTP GET request to the app server endpoint. Default: casualgame.megafuncreative.com/server/version_check.php Returns: status code, response time (ms), response body preview. Checks the same endpoints used by VersionCheckTask.brs.
AI agents call roku_server_check to retrieve information from Roku MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a passive health check operation that queries a remote server endpoint and returns diagnostic information. It has no side effects on the Roku device, app deployment, or external systems. The GET request is non-mutative and only reads server status, placing it firmly in the Read category.
From the tool's definition Tool makes HTTP GET request to check app server health and response time, returning status code, response time, and response body preview. No modifications, deletions, or command execution—purely retrieves server status information.

Register the Roku MCP Server MCP server in PolicyLayer and add a rule for roku_server_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 Roku MCP Server. Nothing to install.
roku_server_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 roku_server_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 roku_server_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.
