What snow_sp_page_manage does on Serac
AI agents use snow_sp_page_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_sp_page_manage is rated Medium
While the tool includes a destructive delete action, the primary design intent is page lifecycle management spanning create/update/clone operations. The delete action is noted to not cascade (limited scope). The majority of actions (list, update, clone, add_widget_instance) are reversible modifications.
From the tool's definition Tool performs multiple write/modification actions: 'update' patches sp_page fields, 'clone' duplicates pages, 'add_widget_instance' creates sp_instance rows. Also includes 'delete' which removes sp_page rows irreversibly.
Attacks that exploit this kind of access
The rule that runs snow_sp_page_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_sp_page_manage, this is the rule to start with:
snow_sp_page_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_sp_page_manage call is checked against it from then on.

Unified tool for ServiceNow Service Portal page lifecycle beyond creation: list, update, delete, clone, add_widget_instance. Wraps sp_page and sp_instance. Actions: - list — list sp_page rows, optionally filtered by portal id, public flag, or title fragment - update — patch sp_page fields (title, public, draft, css, internal) - delete — delete an sp_page row (does not cascade widget instances) - clone — duplicate an sp_page with a new id and title (optionally copying widget instances) - add_widget_instance — place an sp_widget on the page by creating an sp_instance row Use when: the agent needs to maintain Service Portal pages — renaming, retiring, duplicating layouts, or wiring widgets onto a page. For authoring a new sp_page, use snow_create_sp_page; for authoring a new sp_widget, use snow_create_sp_widget. Returns: sp_page rows with sys_id, id, title, public, draft; widget instance rows with sys_id, sp_widget reference, and column placement.
