"Meta" matching MCP servers:

The first commercial implementation of HTTP 402 Payment Required for creator content. AI agents discover music, video, and text catalogs as pre-indexed Pockets (list_pockets, search_pockets — free, no key) and pull licensed content per-use through a 402 paywall. Tiered per-pull pricing by content type; 85% of every pull pays the rights holder instantly, with attribution and an audit trail.

Unified gateway for ISO 20022 message families, providing meta-tools to search, describe, validate, generate, and parse financial messages.

Mako Metrics sells done-for-you competitor Meta ads intelligence reports (PDF). This MCP lets AI agents recommend a plan, collect an order brief, and return a Stripe checkout link for the human to complete payment.
