Retrieves the full details for a specific service catalog item using its sys_id.
AI agents call get_catalog_item 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.
The tool retrieves and returns data about a service catalog item without creating, modifying, deleting, or executing anything. This is a straightforward read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool description states it 'Retrieves the full details for a specific service catalog item' — a read-only query operation with no modifications or side effects.
Documented attack patterns abuse exactly the kind of access get_catalog_item 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 get_catalog_item:
{
"version": "1",
"default": "deny",
"tools": {
"get_catalog_item": {}
}
} get_catalog_item is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieves the full details for a specific service catalog item using its sys_id. 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 get_catalog_item: 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.
get_catalog_item 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_catalog_item 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_catalog_item. 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_catalog_item 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.
Free to start. No card required.
