AI agents use snow_create_project 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 new data (a project record) in ServiceNow, which is reversible through deletion or updates. It does not execute arbitrary code, delete data permanently, or move money. The 'medium' severity reflects that creating enterprise projects could affect resource allocation, scheduling, and organizational planning, but the impact is confined to a single project record creation and can be undone.
From the tool's definition Tool creates a PPM (Project Portfolio Management) project record with name, description, planned start/end dates, and project manager assignment. The description explicitly states 'Create' and references 'pm_project' table creation.
Attacks that exploit this kind of access
Create a PPM project (pm_project) with name, description, planned start/end dates, and a project manager (sys_user). Container for project tasks created via snow_create_project_task. 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_project: 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_project 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_project 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_project. 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_project 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_project 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.
