Feegate Marketplace MCP Server

Official Model Context Protocol server of the Feegate data marketplace — listed in the official MCP Registry as org.feegate/marketplace.

Feegate helps AI-agent-facing data providers monetize APIs with x402: buyers pay per call in USDC on Base, no accounts, no API keys, no subscriptions. This server exposes Feegate's own product catalog and platform metrics over MCP with the same pay-per-call model — Feegate runs on the protocol it sells.

How payment works (x402)

  1. Your MCP client calls a paid tool.
  2. The server responds HTTP 402 with a signed payment request (EIP-3009 transferWithAuthorization).
  3. The client pays USDC on Base (eip155:8453) — gas is sponsored by the facilitator; buyers never need ETH.
  4. The call is retried with the payment header and returns the data. Settlement is verified on-chain.

No account, no API key, no minimum — one HTTP round trip, one micropayment.

For data providers

If you have data (market data, research, rankings, monitoring, anything an agent would pay for), Feegate handles hosting, x402 payment rails, promotion and settlement. See feegate.org/jieshao.
