Mantaray is live: the ad-intelligence MCP
Why we built an MCP server that gives AI assistants eyes on every ad your competitors run — and how to add it to yours in 30 seconds.
Your competitors’ ads are public. Meta, Google, and TikTok all publish them in transparency libraries. But those libraries were built for humans with browser tabs, not for the AI assistants that increasingly do the actual work of marketing.
Mantaray closes that gap. It’s an MCP server that connects Claude, Cursor, and your agents directly to the world’s ad libraries — so competitive intelligence becomes something your assistant just knows how to do.
What it looks like
Add one URL to your assistant:
claude mcp add --transport http mantaray https://mantaray.sh/mcpThen ask, in plain language:
what ads is Acme Cosmetics running on Meta right now?
Mantaray answers in under a second — with verbatim ad copy, creative formats, run dates, and playable video creatives, right in the chat.
Why “Mantaray”
Manta rays don’t chase. They glide through enormous volumes of ocean and filter out exactly what feeds them. Mantaray does the same across the world’s ad libraries — sweeping millions of public ads so your assistant can surface the handful that matter to you.
