RECOMMENDED RULE

The rule that runs add_google_ads_keywords safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Hermoso, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For add_google_ads_keywords, this is the rule to start with:

add_google_ads_keywords Rate-limited

add_google_ads_keywords 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.

FAQ

Questions about add_google_ads_keywords

What does the add_google_ads_keywords tool do? +

Add keywords — and NEGATIVE keywords — to a Google Ads ad group. A Search ad group with no keywords never shows. Each keyword takes text (≤80 chars, ≤10 words) and matchType EXACT | PHRASE | BROAD (default PHRASE). Set negative:true to BLOCK a term instead of targeting it, which is the cheapest way to stop wasted spend. Read back from Google before you are told they exist. If the parent campaign and ad group are already LIVE, a positive keyword starts bidding real money at once — get an explicit yes and pass confirm:true, or add it with paused:true. Negative keywords only restrict spend and never need confirmation. It is categorised as a Write tool in the Hermoso MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on add_google_ads_keywords? +

Register the Hermoso MCP server in PolicyLayer and add a rule for add_google_ads_keywords: 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 Hermoso. Nothing to install.

What risk level is add_google_ads_keywords? +

add_google_ads_keywords is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit add_google_ads_keywords? +

Yes. Add a rate_limit block to the add_google_ads_keywords 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.

How do I block add_google_ads_keywords completely? +

Set action: deny in the PolicyLayer policy for add_google_ads_keywords. 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.

What MCP server provides add_google_ads_keywords? +

add_google_ads_keywords is provided by the Hermoso MCP server (https://app.hermoso.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
