What you can research with Meta Ad Library
Ask Claude to find a competitor's Page and pull every active ad it is running, or search by keyword to see who else is advertising in a category. No setup is needed beyond having MCP Ads connected at all.
- "Find every ad Brand X is running right now"
- "What creative angles is this competitor testing?"
- "Search for active ads mentioning [keyword] in my category"
The coverage limit worth knowing upfront
Meta's public Ad Library website shows every active ad in most countries, but its official API — what Claude actually reads — only returns ordinary commercial ads for ads delivered in the EU or UK. Everywhere else, including the US, it returns only political and social-issue ads, so a US-only competitor search through this tool will come back empty by Meta's own rule, not a broken connection.
- EU/UK advertisers: full commercial ad coverage
- US and most other markets: political/social-issue ads only, via this tool
- For non-EU/UK commercial competitor research, use Google Ads Transparency instead — it covers 180+ countries with no such restriction
