Street FX rates of emerging-market currencies vs USD: latest, history, premium, stress, events
Remote MCP server for EMpulse Street FX Index: street exchange rates of emerging-market currencies vs USD, plus payment-rail and liquidity data.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.empulse-ai%2Fempulse-street-fx/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}A small stdio bridge to the EMpulse Street FX Index MCP server (https://api.empulse.ai/mcp) for clients that
only speak stdio. Standard library only, no build step: every JSON-RPC message from stdin is posted to the remote
server and the answer is written to stdout. Clients that support remote servers can skip this package and connect to
the URL directly — see https://github.com/empulse-ai/empulse-mcp#connect.
Client configuration (Claude Desktop, Cursor, Windsurf, Zed, …):
Environment: EMPULSE_API_KEY (optional — without it the free level applies: free currencies, data up to yesterday,
a daily limit per network), EMPULSE_MCP_URL (default https://api.empulse.ai/mcp).
Street exchange rates of emerging-market currencies against the US dollar — the rate people actually pay where the official rate is managed, lagging or unavailable — built from transaction-based market data and quotes from independent public market sources, with a confidence class and the number of sources on every figure.

Street rate of a currency
The latest street exchange rate of an emerging-market currency against the US dollar (USDT) from the EMpulse Street FX Index, or the rate on a given day: rate (mid), buy, sell, spread, 1/7/30-day changes, confidence class and a ready citation. Free access is delayed by one day; a Pro key gives the current day.
datelangcurrencyrequiredStreet rate history
Daily street rates of a currency between two dates (inclusive, UTC days, at most 400 days per call): rate, buy, sell, confidence per day, plus a summary (first, last, change, low, high). Defaults: the last 30 days up to the latest day of your plan.
langto_datecurrencyrequiredfrom_dateCovered currencies
Every currency of the EMpulse Street FX Index with its status (active, or coverage in progress while market sources are being added), the confidence class and the number of sources behind the latest day, coverage since, and whether your plan covers it.
Takes no parameters.
Official vs street premium
How far the street rate of a currency is from its official central-bank rate: official rate and its publication day, street rate, premium in percent, 7-day average and 30-day maximum. Pro and Enterprise keys.
langcurrencyrequiredFX stress signals
Early warning from the street: a none / watch / alert flag per currency when the street market shows stress (a run of weakening days, a 7-day move in the top decile of the currency's own year, a buy–sell spread blow-out), with the rules that fired and the day the episode started. One currency or all. Pro and Enterprise keys.
currencyCurrency-infrastructure events
A dated feed of events that move street FX in emerging markets — devaluations, cash and withdrawal limits, bans of stablecoin services, currency controls, payment outages — each a short quotation with a link to the public source. Filter by country or currency; `days` back from the latest day of your plan (free: 48-hour delay).
dayscountrycurrencyHourly street rates (Pro)
The street rate of a currency per UTC hour for one day, with the day's summary (vwap, high, low, hours, busiest hour). Pro and Enterprise keys; hours arrive with the daily update.
datecurrencyrequiredPayment rails of a country today
Which payment methods work in a country today and how reliably: for every method class (cards, bank transfers, instant transfers, e-wallets, mobile money, cash, crypto, direct local rails) and direction (pay-ins, payouts) a status — healthy / degraded / outage / no_data — with the time it began and a ready citation. Free level: the free currencies, one day behind. Pro keys of the Rail Health Index: today, every currency, the health index (100 = the rail's own norm), availability, supply.
currencyrequiredPayment-rail status changes (Pro)
Every change of status of a payment method class — degraded, outage, back to healthy — over the last `days` (default 30), newest first, each with a one-line summary ("Bank transfers (pay-ins) in Egypt: degraded since 2026-10-24 14:00 UTC"). Optionally one currency. Pro keys of the Rail Health Index.
dayscurrencyUnmet payment demand
Where payment demand in emerging markets is not being served. Without a currency: the ranking of covered markets by the share of demand no rail served, with the trend. With a currency: its rank and trend (free level, one day behind); Pro keys of the Unmet Demand Map also get the unmet share, the not-connected share, the index against the 90-day norm, the reason classes and the hours of day, per direction and method class.
currencyUSDT liquidity of a currency
Where and when the dollar actually moves through USDT: the liquidity index of a currency (0–100, 50 = the market's own 90-day norm) with a ready citation. Free level: yesterday, the free currencies. Pro keys of USDT Liquidity & Premium: today, every currency, the pay-in / payout balance, the spread, the active hours of day, the premium over the official rate and the supply class.
