Get basic Splunk connection information and list available apps
AI agents call health_check to retrieve information from Splunk without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves connection status and configuration metadata from Splunk without modifying any data, executing code, or triggering side effects. It is a diagnostic/informational endpoint typical of API health checks. The blast radius of misuse is minimal—an attacker gains visibility into Splunk's state and available apps, but cannot manipulate data or execute operations.
From the tool's definition Tool name 'health_check' and description 'Get basic Splunk connection information and list available apps' indicate read-only diagnostic operations. The terms 'Get' and 'list' are explicitly retrieval/query operations with no data modification or execution.
Documented attack patterns abuse exactly the kind of access health_check gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Splunk, and nothing reaches the server without passing your rules. This is the rule we recommend for health_check:
{
"version": "1",
"default": "deny",
"tools": {
"health_check": {}
}
}health_check is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get basic Splunk connection information and list available apps. It is categorised as a Read tool in the Splunk MCP Server, which means it retrieves data without modifying state.
Register the Splunk 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 Splunk. 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 Splunk MCP server (livehybrid/splunk-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Splunk, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
