"Fiat" matching MCP tools:

• priceConverter

  CoinPaprika

  Convert an amount from one crypto or fiat to another at the current rate, e.g. 'how much is 0.5 BTC in USD', 'convert 100 USDC to EUR'. For a plain coin price without an amount, use getTickersById. Read-only; baseCurrencyId and quoteCurrencyId are canonical ids and amount is the quantity to convert. No API key required.

• eur_usd

  Bitstamp

  Bitstamp's own EUR↔USD conversion rate — the buy/sell prices Bitstamp applies when converting fiat balances on the exchange, quoted with the exchange's retail markup (the two legs can differ by several percent). Use when you need the rate a Bitstamp account actually transacts at. For the market FX rate — "EURUSD spot", "current euro to dollar rate", anything macro or reporting-grade — use ecb_exchange_rate, which publishes the official euro reference rate.

• mark_job_paid

  Human Pages

  Record payment for an ACCEPTED job. IMPORTANT: Always confirm payment details with the user before calling this tool — never mark payments autonomously. Job must be in ACCEPTED status (use get_job_status to check). Crypto payments (usdc, eth, sol): provide tx hash + network → verified on-chain instantly, job moves to PAID. Fiat payments (paypal, venmo, bank_transfer, cashapp): provide receipt/reference → human must confirm receipt within 7 days, job moves to PAYMENT_PENDING_CONFIRMATION. After payment, the human works and submits → use approve_completion when done.

• pay_mail_with_shared_payment_token

  PostAgent — Print and Mail

  Autonomous, no-browser FIAT payment for a locked quote using a Stripe Shared Payment Token (SPT / Machine Payments Protocol). Use this when the agent can mint an SPT on the buyer's behalf and wants to pay by card/wallet without a human in a browser (prefer x402 first if the agent has a USDC-on-Base wallet; this is the autonomous fiat alternative). CHARGES MONEY AND IS IRREVERSIBLE: the server authorizes the SPT, prints the letter, then captures — a job comes back inline (no polling needed). Only call after the user has explicitly confirmed the recipient, sender, content, and price from create_mail_quote. Minting the token (the agent's responsibility, NOT this server): the SPT must be scoped to THIS seller's Stripe profile and to at least the quote amount. The quote's `paymentOptions` entry for `mpp` carries the `stripeProfileId`, `currency`, `maxAmountCents`, and `expiresAt` you need. Mint it with the buyer's payment method via the Stripe `@stripe/link-cli` (`spend-request create … --network-id <stripeProfileId> --credential-type shared_payment_token`) or the SharedPaymentIssuedToken API, then pass the resulting `spt_…` here. SPTs are US-only and cards carry a 0.50 USD minimum. Returns an error if MPP is not enabled/configured on the server.

• create_offramp_session

  FiatDock

  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.

• ramp.agent_card

  DPX — Institutional Cross-Border Settlement

  Create a scoped Ramp Agent Card — a single-use virtual card with a merchant and amount cap, expires after first authorization or 12 hours. Used to fund the fiat leg of a DPX settlement without pre-funding a crypto wallet. Returns a task ID; poll ramp.agent_card_status to get PAN/CVV once ready. Requires cards:read_agentic scope (granted via ramp.connect).

• currency_convert

  Inferventis MCP Server

  Converts a monetary amount from one currency to another using live exchange rates sourced from the Frankfurter API (European Central Bank data). Returns the converted amount, the exact exchange rate applied, and the timestamp of the rate. Supports 30+ currencies including USD, EUR, GBP, JPY, CHF, AUD, CAD, SEK, NOK, DKK, SGD, HKD, and all major ISO 4217 codes. Use currency_convert when an agent needs to convert prices, invoices, salaries, payments, or any financial figure between fiat currencies in real time with full ECB-backed rate metadata. Prefer currency_convert_lite or currency_fx_lite when only the numeric converted amount and rate are needed without metadata. Use currency_rates when the conversion must use a historical rate from a specific past date. Do not use this tool for cryptocurrency conversion — use crypto_fx_rates (amount conversion via CoinAPI) or crypto_price (spot price lookup via CoinGecko).

• get_convert

  webbersites-x402-data-api

  Live crypto conversion at CoinGecko prices: any coin to any coin or fiat, and fiat to coin. ?amount=0.5&from=bitcoin&to=ethereum — common tickers (btc, eth, sol…) accepted. Returns the rate, the converted amount, and the underlying prices. Prices cached ≤30s; cheap enough to call in a loop. ($0.001 per call, paid via x402)

• flat_auth

  Flat Cash

  Authenticate an existing FlatID user. Actions: password (login with username + password to get a fresh API key with full permissions), token (verify an existing API key is valid and see account info). Use this if you already have a FlatID account from flat.cash and want to access it from your LLM. IMPORTANT: Ask for username first, then password — one question per message. After successful login, offer to store the password in environment variables for automatic future logins.

• onramp-coverage

  x402 Bazaar

  Can money get in and out of crypto here, and how? — The feasibility check before you ask a user for money: which fiat-in and cash-out rails Coinbase actually runs in a country, the currencies and min/max limits for each, and how many assets across which networks. Distinguishes a country with card rails from one where crypto can only be transferred in — a difference most integrations discover only after a user fails. 122 countries covered. Required input: country. Priced $0.02 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.

  Connector

• currency_convert_lite

  Inferventis — Financial Data, News & Web MCP

  Converts a monetary amount between any two fiat currencies using live exchange rates from the Frankfurter API (European Central Bank data). Returns the converted amount and the exchange rate applied. This is a lightweight variant of currency_convert — minimal response without rate timestamp or source attribution. Use currency_convert_lite when only the converted value and rate are needed and ECB/Frankfurter-sourced rates are preferred. Prefer currency_convert when the agent also needs rate timestamp and richer structured output. Prefer currency_fx_lite for the same minimal output (amount + rate) when the ECB data source is not specifically required — both return identical fields but draw from different rate providers. Use currency_rates when a historical rate from a specific past date is required (e.g. accounting, tax, or audit). Use currency_convert_open as a fallback when Frankfurter is unavailable or rate-limited. Does not support cryptocurrency pairs — use crypto_price or crypto_fx_rates for crypto-to-fiat conversions. Accepts all major ISO 4217 currency codes (USD, EUR, GBP, JPY, CHF, AUD, CAD, SGD, NOK, SEK, DKK, PLN, CZK, HUF, etc.).

• finnhub_stock_quote

  Inferventis MCP Server

  Retrieves real-time stock price quotes and company information for any publicly traded company via the Finnhub API. Returns current price, intraday high and low, percentage change from previous close, previous close price, sector, and exchange. Use stock_quote when an agent needs to look up a stock price, check intraday market performance, retrieve company sector data, monitor equity portfolio values, or answer any question about the current trading price of a publicly listed company. Prefer stock_quote over stock_price_lite when the agent needs price change, intraday range, company name, or sector — stock_price_lite returns only the raw current price with no additional context. Do not use for cryptocurrency prices — use crypto_price (CoinGecko, 10,000+ assets) or crypto_price_lite for a lightweight variant. Do not use for fiat currency conversion — use currency_convert or currency_fx_lite. Requires a Finnhub API key to be configured on the server.

• flat_register

  Flat Cash

  Register a new FlatID account. IMPORTANT: Do NOT call this tool until you have asked the user for EACH field one at a time (see llms.txt Conversational Onboarding Flow). Ask for username first, then primary email, then recovery email, then password — one question per message. REQUIREMENTS: 2 valid email addresses (primary + recovery, must be different) and a password of at least 12 characters. After calling, 6-digit codes are sent to BOTH emails. User must verify BOTH within 10 minutes using flat_verify or the account is deleted. After verification, CELEBRATE the new FlatID and offer to store the password in env variables for auto-login.

Supports all major cryptocurrencies including Bitcoin (BTC), Ethereum (ETH), Solana (SOL), XRP, Cardano (ADA), Dogecoin (DOGE), Polygon (MATIC), Chainlink (LINK), Avalanche (AVAX), and 10,000+ additional coins. Use crypto_price when an agent needs the full market picture for a digital asset — price, change, market cap, and volume in one call. Prefer crypto_price_lite when only the spot price and 24h change are needed and a smaller response payload is preferred. Use crypto_fx_rates (via CoinAPI) when converting a specific amount between a cryptocurrency and fiat, or between two cryptocurrencies.

• crypto_price_lite

  Inferventis — Financial Data, News & Web MCP

  Retrieves the current spot price and 24-hour change for any cryptocurrency using the CoinGecko public API. Returns price, percentage change, and a timestamp. This is a lightweight variant of crypto_price that omits extended market data (market cap, volume) — use it when only the raw price and 24h direction are needed. Prefer crypto_price when the agent also needs market capitalisation, trading volume, or richer structured output. Use crypto_fx_rates when converting a specific amount between a cryptocurrency and fiat (e.g. 'convert 0.5 BTC to USD') rather than looking up a spot price. Supports all major coins including BTC, ETH, SOL, XRP, ADA, DOGE, and 10,000+ CoinGecko-listed assets. Accepts ticker symbols (BTC, ETH) or full names (bitcoin, ethereum). Target currency defaults to USD but accepts any ISO 4217 code.

• currency_convert_open

  Inferventis — Financial Data, News & Web MCP

  Converts a monetary amount between two fiat currencies using live exchange rates from an open currency exchange API. Returns the converted amount and the rate applied. Use currency_convert_open as an alternative live-rate source when currency_convert (Frankfurter/ECB) or currency_fx_lite are unavailable or rate-limited. The underlying source is an open public exchange rate feed suitable for informational use. Prefer currency_convert or currency_rates when ECB-auditable Frankfurter rates are required for accounting or compliance. Prefer currency_convert_lite for the same minimal output (amount + rate) backed by ECB/Frankfurter rates. Prefer currency_fx_lite for lightweight mid-market conversions. Does not support cryptocurrency pairs — use crypto_fx_rates for any conversion involving a digital asset.
