Request a snapshot backup of the current ServiceNow instance under a chosen name, optionally including attachments. Returns the backup name and timestamp; the backup itself runs asynchronously.
AI agents use snow_backup_instance 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 backup artifact (snapshot) which is a reversible operation—backups can be replaced or deleted later. While it has significant operational impact on system state and resources, it does not permanently delete data (ruling out Destructive), execute arbitrary code (Execute), or involve financial transactions (Financial).
From the tool's definition Creates a snapshot backup of the ServiceNow instance under a chosen name; specified as 'request a snapshot backup' which triggers data creation/capture rather than retrieval or destruction.
Attacks that exploit this kind of access
Request a snapshot backup of the current ServiceNow instance under a chosen name, optionally including attachments. Returns the backup name and timestamp; the backup itself runs asynchronously. 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_backup_instance: 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_backup_instance 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_backup_instance 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_backup_instance. 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_backup_instance 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_backup_instance 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.
