List all KV store collections across apps. Returns: List of KV store collections with metadata including app, fields, and accelerated fields
AI agents call list_kvstore_collections 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 KV store collection metadata (app, fields, accelerated fields) without modifying, deleting, or executing any operations. It is purely informational, matching the 'Read' category for data retrieval operations.
From the tool's definition Tool name is 'list_kvstore_collections' and description states it 'List all KV store collections' and 'Returns: List of KV store collections with metadata'. The verb 'list' and action of returning metadata indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_kvstore_collections 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 list_kvstore_collections:
{
"version": "1",
"default": "deny",
"tools": {
"list_kvstore_collections": {}
}
}list_kvstore_collections is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all KV store collections across apps. Returns: List of KV store collections with metadata including app, fields, and accelerated fields. 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 list_kvstore_collections: 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.
list_kvstore_collections 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 list_kvstore_collections 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 list_kvstore_collections. 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.
list_kvstore_collections 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.
