Lists user stories with optional filtering and pagination.
AI agents call list_stories to retrieve information from Snow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries user story data from ServiceNow without creating, modifying, deleting, or executing operations. It has no capability to alter state or trigger external actions. The filtering and pagination are standard query parameters for scoped data retrieval. Blast radius is minimal—misuse would at worst expose user story information visible to the authenticated user already.
From the tool's definition Tool name 'list_stories' and description 'Lists user stories with optional filtering and pagination' indicate a pure data retrieval operation.
Documented attack patterns abuse exactly the kind of access list_stories gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Snow, and nothing reaches the server without passing your rules. This is the rule we recommend for list_stories:
{
"version": "1",
"default": "deny",
"tools": {
"list_stories": {}
}
}list_stories is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Lists user stories with optional filtering and pagination. It is categorised as a Read tool in the Snow MCP Server, which means it retrieves data without modifying state.
Register the Snow MCP server in PolicyLayer and add a rule for list_stories: 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 Snow. Nothing to install.
list_stories 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_stories 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_stories. 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_stories is provided by the Snow MCP server (shunyaai/snow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Snow, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
