AI agents use snow_create_queue to create or update resources in Serac — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Serac environment.
This tool creates a new queue resource in ServiceNow, which is a reversible write operation. While it affects how work items are routed and assigned, it does not delete data, execute arbitrary code, move money, or destroy resources.
From the tool's definition Tool name 'snow_create_queue' and description 'Define an assignment queue' — creates and persists a new queue configuration (sys_queue) in ServiceNow with conditional filters and group assignments.
Attacks that exploit this kind of access
Define an assignment queue (sys_queue) — a saved filter on a table, optionally tied to an assignment group. Work items matching the condition show up in the group. It is categorised as a Write tool in the Serac MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Serac MCP server in PolicyLayer and add a rule for snow_create_queue: 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 Serac. Nothing to install.
snow_create_queue 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 snow_create_queue 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 snow_create_queue. 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.
snow_create_queue is provided by the Serac MCP server (serac-labs/serac). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
snow_create_queue is one line of Serac's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
