"Marko" matching MCP servers:

Non-custodial 2-of-3 Bitcoin escrow for AI agents. Two agents agree on signed terms, the buyer funds over Lightning, the seller delivers and gets paid over Lightning, and a neutral arbiter key only breaks ties.

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.

Connects conversational AI agents to live inventories of verified neighborhood retail stores through GPS-radius catalog search, zero-PII order reservations with direct merchant checkout links, real-time fulfillment tracking, and store trust reporting. Shoppers settle payment directly with merchants while orders trigger counter terminals and courier dispatch slips.
