AI agents use servicenow_source_control to create or update resources in Servicenow Api — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Servicenow Api environment.
Although the tool description is empty, reducing confidence slightly, the tool name and server context suggest this tool performs write operations such as committing code, managing repositories, or modifying configurations within ServiceNow's source control integration. These are reversible write operations (commits can be reverted, branches can be deleted).

PolicyLayer is an MCP gateway — it sits between your AI agents and Servicenow Api, and nothing reaches the server without passing your rules. This is the rule we recommend for servicenow_source_control:
{
"version": "1",
"default": "deny",
"tools": {
"servicenow_source_control": {
"limits": [
{
"counter": "servicenow_source_control_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}servicenow_source_control 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.
