Get metadata for a specific Splunk index. Args: index_name: Name of the index to get metadata for Returns: Dictionary containing index metadata
AI agents call get_index_info 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 and queries index metadata without modifying, deleting, executing code, or causing financial impact. It is a simple read operation that returns information about an existing Splunk index.
From the tool's definition The tool gets metadata for a specific Splunk index and returns a dictionary of index metadata. The description uses 'Get metadata' and 'Returns', indicating a read-only retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_index_info 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 get_index_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_index_info": {}
}
}get_index_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get metadata for a specific Splunk index. Args: index_name: Name of the index to get metadata for Returns: Dictionary containing index metadata. 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 get_index_info: 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.
get_index_info 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 get_index_info 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 get_index_info. 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.
get_index_info 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.
