Updates an existing service catalog category's title or description.
AI agents use update_catalog_category to create or update resources in Snow — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Snow environment.
This tool creates or modifies data reversibly without deleting or destroying information. It updates metadata (title/description) of a catalog category, which is a classic Write operation. Severity is medium because misconfiguration of catalog categories could impact service offerings and user experience, but changes are reversible and lack the blast radius of Execute or Destructive operations.
From the tool's definition Tool name 'update_catalog_category' and description 'Updates an existing service catalog category's title or description' indicate modification of existing data (title/description fields) in a reversible manner.
Documented attack patterns abuse exactly the kind of access update_catalog_category 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 update_catalog_category:
{
"version": "1",
"default": "deny",
"tools": {
"update_catalog_category": {
"limits": [
{
"counter": "update_catalog_category_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_catalog_category stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Updates an existing service catalog category's title or description. It is categorised as a Write tool in the Snow MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Snow MCP server in PolicyLayer and add a rule for update_catalog_category: 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.
update_catalog_category is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_catalog_category 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 update_catalog_category. 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.
update_catalog_category 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.
