AI agents call check_dashboard_health to retrieve information from Kibana without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though check_dashboard_health only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Perform health check on a Dashboard to detect broken references, performance issues, etc.. It is categorised as a Read tool in the Kibana MCP Server, which means it retrieves data without modifying state.
Register the Kibana MCP server in PolicyLayer and add a rule for check_dashboard_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 Kibana. Nothing to install.
check_dashboard_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 check_dashboard_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 check_dashboard_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.
check_dashboard_health is provided by the Kibana MCP server (TocharianOU/mcp-server-kibana). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
