FiatDock MCP Server

PAID ($0.002 USDC via x402). Name, symbol, decimals and total supply for any ERC-20 contract on Base — the identity fields an agent needs before pricing or safety-checking a token. Without payment this returns the 402 challenge; the fiatdock-mcp npm package pays automatically. A non-ERC-20 / bad address returns 4xx and is NOT charged; on any RPC failure it returns 5xx and is NOT charged.

FREE real-time price snapshot for any EVM token by contract address: USD price, 5m/1h/6h/24h change, liquidity, 24h volume, market cap/FDV and the most-liquid DEX pair (DexScreener). Or pass a major symbol (ETH/BTC) for a Coinbase spot price. Read-only, free.

PAID ($0.05 USDC via x402). The full picture on an ERC-20 in ONE call: live price, liquidity, 24h volume, market cap/FDV and the most-liquid DEX pair (DexScreener) TOGETHER with the complete safety verdict — honeypot / buy&sell tax / owner privileges / holder concentration / LP-locked / CEX listing (GoPlus). One payment instead of chaining token_price + token_safety. Without payment this returns the 402 challenge; the fiatdock-mcp npm package pays automatically. A bad address returns 400; no liquidity/security data returns 404; an upstream outage or partial scan returns 502 — none is charged. Not financial advice.

PAID ($0.01 USDC via x402). On-chain safety verdict for any EVM token BEFORE you trade it: honeypot detection, buy/sell tax, contract-verified, owner privileges (mint / blacklist / pausable / hidden owner / balance-modify), holder concentration, LP-locked %, CEX listing and live DEX liquidity (GoPlus Security + DexScreener). Returns verdict safe|caution|danger with the exact risks. Without payment this returns the 402 challenge; the fiatdock-mcp npm package (AGENT_PRIVATE_KEY) pays automatically. Not financial advice.

PAID ($0.005 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-laundering / blacklist and more) — the loop input for triaging a counterparty, payout target or approval spender. Without payment this returns the 402 challenge; the fiatdock-mcp npm package pays automatically. A bad address returns 400; if Base RPC or GoPlus is unavailable it returns 502 — neither is charged.

PAID ($0.001 USDC via x402). The latest Base block number plus its timestamp — a freshness/liveness probe for agents that need to know the chain head. 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 charged.

Invoke a listed FiatDock service. PAID listings go THROUGH the gateway (POST /s/:id) so the non-custodial split is enforced — normally TWO payments (99% seller + 1% FiatDock), or ONE full-price payment to the seller during that seller's first-month 0% launch window; this remote /mcp cannot sign payments, so it returns the gateway's 402 challenge as an error (use the fiatdock-mcp npm package with AGENT_PRIVATE_KEY to pay whatever the 402 lists automatically). FREE / first-party listings are forwarded to their real MCP endpoint directly (no payment). Pass the service's expected request body as `args`.

PAID ($0.001 USDC via x402). The native ETH balance of any address on Base, in wei and ETH. Without payment this returns the 402 challenge; the fiatdock-mcp npm package pays automatically. An invalid address returns 400 and is NOT charged; on any RPC failure it returns 5xx and is NOT charged.

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 charged.

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 emailedTo). Paid endpoint ($1.00 USDC via x402) — without payment this returns the 402 challenge; use the fiatdock-mcp npm package with AGENT_PRIVATE_KEY for automatic payment. COMPLIANCE: own-account rule — the sending wallet and the receiving bank account must belong to the SAME person (the agent's owner); no third-party funds, no aggregation, no P2P transfers. 18+; served worldwide via our licensed provider across ~160 countries — EUR bank transfer in the SEPA zone (incl. Portugal), card/Apple Pay/Google Pay elsewhere — excluding US persons, sanctioned countries and the UK (NOT the UK). Crypto is volatile; not investment advice.

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).

PAID ($0.002 USDC via x402). Supply, peg health and per-chain breakdown for USDC and other stablecoins: total circulating supply, deviation from the $1.00 peg, peg mechanism, the amount circulating on Base (with its share of total) and the top chains by supply (DefiLlama). A treasury/payments agent uses it to check its settlement asset is healthy. Without payment this returns the 402 challenge; the fiatdock-mcp npm package pays automatically.
