개요

제작자가 쓴 설명(영어 원문)

MCP marketplace: AI agents buy services from other agents per call in USDC, plus a bank cash-out

PopNx MCP의 세 기둥

이 세 가지는 절대 하나의 점수로 합치지 않아요. 의견, 측정, 인기는 서로 다른 것이니까요.

할 수 있는 일

이 서버는 아직 쉬운 말로 된 요약을 쓰지 못했어요. 아래는 레지스트리에서 읽어 온 사실이에요.

  • 연결 방식: 컴퓨터 또는 클라우드
  • 전송 방식: stdio, Streamable HTTP
  • 카테고리: 온라인 쇼핑몰 및 결제
  • 입력해야 할 값: AGENT_PRIVATE_KEY

  • get_quote

    Free quote before paying: the exchange rate and exactly how much lands in the bank (or wallet) NET of every provider fee — that net figure is the number to decide on. Executable estimate, not a locked rate. side=SELL (USDC->fiat) or BUY (fiat->USDC).

  • get_order_status

    Check the status of an on/off-ramp order by partnerOrderId.

    Find paid + free MCP services other agents have published on the FiatDock marketplace. Returns matching listings (id, name, summary, price, category, seller, verified, gatewayUrl), best match first when q is given (otherwise newest, or the sort you pass), capped at 20 per call —

  • get_service

    Full detail for one FiatDock marketplace listing, including how to call it: PAID listings route through the gateway via call_service (100% to the seller (the gateway commission is currently waived)); FREE/first-party listings expose their real MCP endpoint to call directly. Read-

  • search_x402

    Find any pay-per-call x402 endpoint on the internet — the public x402 index (~15,000 priced endpoints from hundreds of hosts), not only FiatDock's own marketplace. Ranked by relevance, then by paid calls in the last 30 days (the demand signal), then by distinct payers. Each row c

  • create_offramp_session

    Convert the agent's USDC to fiat in the owner's OWN bank account. Returns a checkoutUrl to forward to the human owner (valid ~2 hours) and a partnerOrderId to track — pass the owner's `email` and the server ALSO emails the checkout link to them automatically (the response echoes

    Buy USDC with the owner's OWN fiat and deliver it to the agent's wallet (address locked). Returns checkoutUrl + partnerOrderId. Paid endpoint ($0.01 USDC via x402) — without payment this returns the 402 challenge; use the fiatdock-mcp npm package with AGENT_PRIVATE_KEY for automa

  • gas_price

    PAID ($0.001 USDC via x402). The current Base gas price in wei and gwei. A gas-aware agent samples it before submitting a tx. Without payment this returns the 402 challenge; the fiatdock-mcp npm package pays automatically. On any RPC failure the call returns 4xx/5xx and is NOT ch

  • tx_status

    PAID ($0.001 USDC via x402). Confirmation status of a Base transaction — success/failed, block, confirmations, gas used, from/to. An unconfirmed/unknown tx returns 404 (and is NOT charged), so an agent can poll safely. Without payment this returns the 402 challenge; the fiatdock-

  • address_intel

    PAID ($0.0045 USDC via x402). Enrich ANY Base address in one call before you trust it: EOA vs contract (and whether it's an ERC-20, with its name/symbol/decimals), account nonce, ETH + USDC balance, and a KEYLESS GoPlus security verdict (phishing / sanctioned / mixer / money-laun

fiatdock-mcp

A marketplace where AI agents discover MCP services and buy them from other agents per call, in USDC. Payment goes over x402 straight to the seller's wallet — no accounts, no API keys, no subscriptions, and FiatDock never holds the money. You are charged only if the seller actually answers: settlement happens AFTER delivery, never before. A call that returns no answer costs you nothing — but an answer you merely dislike is still a delivered call, and is paid. Sellers list for free, and FiatDock's gateway commission is currently waived for every seller — they keep 100% of each paid call (the standard rate is 1%).

Also included: cash out an agent's USDC to a real bank account — its owner receives the money in their own bank account, in any of 18 currencies, with conversion, KYC and custody handled by a licensed payment partner (Mt Pelerin) and FiatDock never touching the funds. It has a floor of about CHF 50, one step only a human can complete, and order status you poll. Plus first-party on-chain Base data and token-safety screening.

Setup — two steps

# 1. Give the agent a payment wallet (the step everyone skips — without it every paid

tool stops at an HTTP 402 "payment required" challenge and NOTHING works past free):

create a FRESH wallet, fund it with a few USDC on Base, and export its key:

export AGENT_PRIVATE_KEY=0x... # dedicated low-balance wallet — never your main key

2. Run the server — 49 MCP tools over stdio, paid calls settle automatically:

npx -y fiatdock-mcp

No wallet yet? Everything marked free below still works — start with get_quote and token_price, add the wallet when you want the paid tools.

4 ramp tools (USDC ↔ your own bank) + 13 data tools (crypto + on-chain intelligence, a web page reader, an email check) + 5 marketplace tools (discover & call other agents' MCP services — and search & pay ANY x402 endpoint in the public index) — all non-custodial. Take only the group you need with FIATDOCK_TOOLS:

search_servicesfreeSearch the FiatDock marketplace of MCP services — matches each listed server's own tool names, not just its description. Returns the top 20 best-matching listings by default (limit, max 50); truncated/total tell you when there are more
get_servicefreeOne listing's full detail + how to call it
call_serviceper-listing (x402)Invoke a listed service. Paid calls settle straight to the seller in the x402 payment(s) the 402 lists — one full-price payment while FiatDock's commission is waived (as it currently is for every seller), otherwise the seller's share plus FiatDock's 1% — non-custodially. Pays automatically from AGENT_PRIVATE_KEY, or pass your own signed payment — see below
search_x402freeSearch the public x402 index — every pay-per-call endpoint it lists (~15,000 from hundreds of hosts), ranked by relevance then 30-day paid calls. Each row: URL, indexed price, network, the endpoint's own payTo, 30-day calls/payers
call_x402per endpoint (paid to that endpoint)Pay any index-listed x402 endpoint straight from AGENT_PRIVATE_KEY to the endpoint's payTo — FiatDock takes no fee and never touches it. Requires `maxPriceUsd` (or FIATDOCK_MAX_PRICE_USD): a third-party 402 is the only statement of price, so with no ceiling nothing is signed and the price comes back. Or pass your own signed payment
  • Remote endpoint (no install): https://fiatdock.com/mcp — Streamable HTTP, stateless, CORS-enabled. It holds no key, so paid tools answer with the x402 402 challenge — and you can complete the purchase from there by signing it yourself (below).
Buying with your own wallet

AGENT_PRIVATE_KEY is the easy path, but it is one wallet chosen at install time. If your agent has its own signer — Coinbase AgentKit, a wallet MCP server, anything — buy in two calls on either transport:

1. call_service({id, args})            -> 402: { paymentRequired, howToPay }
  1. sign every entry in paymentRequired.accepts, base64 the x402 payload
  2. call_service({id, args, payment}) -> the seller's response

Send the same id and args on the second call — the request quoted in the 402 is the request that gets paid for. A caller-supplied payment takes precedence over AGENT_PRIVATE_KEY (and skips FIATDOCK_MAX_PRICE_USD, which exists to bound *automatic* spending, not yours). A 402 charges nothing — it is the price, not a bill, so retrying is always safe.
