What snow_fsm_work_order_manage does on Serac
AI agents use snow_fsm_work_order_manage 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.
Why snow_fsm_work_order_manage is rated Medium
The tool supports both read operations (list, get) and write operations (create, assign). Since it can create new work orders and assign them to technicians, it modifies state in the system reversibly. This is categorized as Write rather than Execute because the operations are data creation/modification, not arbitrary code execution or system commands.
From the tool's definition Tool includes 'create' and 'assign' actions that modify work order data: 'create — create a new work order' and 'assign — assign the work order to a technician'.
Attacks that exploit this kind of access
The rule that runs snow_fsm_work_order_manage safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Serac, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For snow_fsm_work_order_manage, this is the rule to start with:
snow_fsm_work_order_manage 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Serac, apply this rule, and every snow_fsm_work_order_manage call is checked against it from then on.

Unified tool for ServiceNow Field Service Management work orders. Wraps the wm_order, wm_task and wm_order_history tables installed by the Field Service Management plugin (com.snc.work_management). Actions: - list — list work orders, optionally filtered by state, assignment_group, assigned_to, or location - get — retrieve a single work order by sys_id or number (includes related task and history counts) - create — create a new work order with short_description, location, contact, priority, and optional scheduling window - assign — assign the work order to a technician (assigned_to) and/or dispatch group (assignment_group) - schedule — set the scheduled work_start and work_end on the work order - update_status — transition the state field by human-readable state name (Draft, Scheduled, En Route, Onsite, Closed Complete, ...) - list_tasks — list the wm_task rows linked to a parent work order Use when: the agent needs to create, dispatch, schedule, or report on field-service work orders. Requires the Field Service Management plugin (com.snc.work_management) on the target instance — every action surfaces a clear PLUGIN_MISSING error if wm_order is absent. Returns: work order records with sys_id, number, short_description, state, priority, assignment_group, assigned_to, location, contact, work_start, work_end. For list_tasks returns wm_task rows with sys_id, number, short_description and state. 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.
