Creates a new Normal, Standard, or Emergency change request.
AI agents use create_change_request to create or update resources in Snow — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Snow environment.
This tool creates new change request records in ServiceNow, which is a reversible write operation—change requests can be cancelled, closed, or reopened. However, the severity is high because creating change requests initiates formal change management processes that can affect production systems, require approvals, and have business impact.
From the tool's definition Tool description states it 'Creates a new Normal, Standard, or Emergency change request.' The verb 'creates' indicates data creation. ServiceNow change requests trigger documented change management workflows that modify infrastructure and systems.
Documented attack patterns abuse exactly the kind of access create_change_request gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Snow, and nothing reaches the server without passing your rules. This is the rule we recommend for create_change_request:
{
"version": "1",
"default": "deny",
"tools": {
"create_change_request": {
"limits": [
{
"counter": "create_change_request_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_change_request 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.

Creates a new Normal, Standard, or Emergency change request. It is categorised as a Write tool in the Snow MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Snow MCP server in PolicyLayer and add a rule for create_change_request: 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 Snow. Nothing to install.
create_change_request 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 create_change_request 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 create_change_request. 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.
create_change_request is provided by the Snow MCP server (shunyaai/snow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Snow, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
