AI agents use pause_line_item to create or update resources in Google Ad Manager MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Google Ad Manager MCP Server environment.
Pausing a line item stops ad delivery but is a reversible action (can be resumed), placing it in the Write category. However, the blast radius is high because pausing an active line item immediately halts ad serving, potentially causing significant revenue loss or campaign disruption. Confidence is moderate because the description is empty and behavior is inferred from the name alone.
From the tool's definition Tool name: pause_line_item; description is empty. Inferred from name that it pauses a line item, which is a reversible state change (can be unpaused).

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