Cross-reference platform and ad format to see which formats perform best on each platform. Use for:
AI agents call platform_format_matrix 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 displays performance metrics comparing platforms and ad formats against historical data. It has no side effects: it does not create, modify, delete, execute code, or trigger financial transactions.
From the tool's definition The tool is described as 'cross-reference' and 'see which formats perform best' — verbs indicating data retrieval and analysis.
