FiatDock

FiatDock is a marketplace where MCP servers get paid. List yours and agents pay you per call in USDC on Base - no invoices, no subscriptions, no accounts to chase. Payments settle wallet-to-wallet via x402; FiatDock never holds funds. Commission is 1%, waived for your first 30 days.

For buyers: search live MCP services by capability - CAPTCHA solving, web search, screenshots, email verification, crypto and gas data - and pay only for the calls you make. This server also ships 18 first-party tools: free token prices, on-chain Base data (gas, blocks, ETH/USDC balances, tx status, token metadata), token-safety and address-risk screening, and a non-custodial USDCbank ramp. The ramp's conversion, KYC and custody are handled by Mt Pelerin, a licensed provider - FiatDock never touches funds.

Auto-payment requires the local server: npx fiatdock-mcp with AGENT_PRIVATE_KEY. On the remote endpoint (https://fiatdock.com/mcp), call_service returns the x402 402 challenge for your client to sign

Requires a local install: run the server on your machine, then point your client at it.
