Lists epics from ServiceNow with filtering options.
AI agents call list_epics 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 and queries epic data from ServiceNow without side effects. Filtering options allow customized queries but do not modify, delete, or execute external operations. The blast radius of misuse is minimal—an agent could retrieve unwanted epic information, but cannot cause data loss or irreversible changes. No financial transactions or code execution are involved.
From the tool's definition Tool name 'list_epics' and description 'Lists epics from ServiceNow with filtering options' indicate data retrieval with no modification or deletion. The verb 'lists' and the context of filtering query results are consistent with Read operations.
Documented attack patterns abuse exactly the kind of access list_epics 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_epics:
{
"version": "1",
"default": "deny",
"tools": {
"list_epics": {}
}
}list_epics is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Lists epics from ServiceNow with filtering options. 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_epics: 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_epics 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_epics 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_epics. 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_epics 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.
