Facebook Ad Library MCP server and CLI for Claude Code, Codex and AI agents. 9 tools that read every ad running on Facebook, Instagram, Messenger, Threads and Audience Network, for any advertiser in any country, free and with no API key.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"thenavidm-facebook-ad-library-mcp-cli","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
