Compare performance across ad formats (banner, interstitial, rewarded, native). Use for:
AI agents call format_comparison to retrieve information from AdMob MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and compares existing AdMob performance data across different ad format types. It has no side effects—it does not create, modify, delete, or execute arbitrary operations. It falls squarely into the Read category (retrieves/queries data for analysis).

Register the AdMob MCP Server MCP server in PolicyLayer and add a rule for format_comparison: 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 AdMob MCP Server. Nothing to install.
format_comparison is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the format_comparison 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 format_comparison. 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.
format_comparison is provided by the AdMob MCP Server MCP server (willhou/admob-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
