81 of Google Ads MCP Server's 142 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.
PolicyLayer is an MCP gateway — it sits between your AI agents and Google Ads MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:
{
"google_ads_update_campaign_budget_v2": {
"deny_if": [
{
"conditions": [],
"on_deny": "Requires human approval."
}
]
}
} Financial tools should be explicitly enabled per use case, not open by default.
{
"google_ads_batch_status_change": {
"limits": [
{
"counter": "google_ads_batch_status_change_per_hour",
"window": "hour",
"max": 30,
"scope": "grant"
}
]
}
} Prevents bulk unintended modifications from agents caught in loops.
{
"google_ads_account_performance": {
"limits": [
{
"counter": "google_ads_account_performance_per_minute",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
} Controls API costs and prevents retry loops from exhausting upstream rate limits.

Yes. The Google Ads MCP Server server exposes 1 financial tools including google_ads_update_campaign_budget_v2. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. PolicyLayer lets you block financial tools by default, require human approval, or set per-tool rate limits — enforced on every call.
The Google Ads MCP Server server has 77 write tools including google_ads_batch_status_change, google_ads_add_audience_to_ad_group, google_ads_add_audience_to_campaign. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Google Ads MCP Server.
142 tools across 3 categories: Execute, Read, Write. 61 are read-only. 81 can modify, create, or delete data.
Register the Google Ads MCP Server MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.
