Overview

AllRatesToday exchange rates (hosted) connects MCP clients to AllRatesToday through a remote Streamable HTTP endpoint, so no local package installation is needed. It provides live mid-market quotes, historical series, multi-target lookups, central-bank tables, daily reference rates, currency validation, and trial-key provisioning. Keyless requests can use official central-bank data, while an API key unlocks broader live-rate access and paid-plan features such as historical queries. Reach for it when an agent needs current or reproducible fiat exchange rates rather than cryptocurrency, commodity, or amount-conversion calculations.

Use cases

  • Retrieve a current EUR/USD mid-market quote
  • Compare one currency with several targets
  • Review a currency pair over a fixed historical window
  • Retrieve an institution's published rate for accounting
  • Build a reproducible daily FX reference series

Key features

  • Hosted Streamable HTTP MCP endpoint
  • Live and historical fiat exchange rates
  • Official central-bank and tax-authority tables
  • Daily reference-rate data
  • 160+ ISO 4217 currency codes
  • Keyless access plus trial-key provisioning

How AllRatesToday exchange rates (hosted) works

What AllRatesToday exchange rates (hosted) MCP server does

AllRatesToday exchange rates (hosted) exposes foreign-exchange data through the hosted MCP endpoint at https://allratestoday.com/api/mcp. It is intended for MCP-compatible applications that need fiat currency information without running a local process. The service covers more than 160 ISO 4217 currencies and distinguishes between several kinds of rates:

  • Live mid-market rates for market-oriented quotes and conversions.
  • Official rates published by named central banks or tax authorities.
  • A once-daily reference rate designed for reproducible reporting and research.
  • Historical series over fixed periods or rates at specified past times.

The response identifies relevant dates and, where applicable, whether a value was derived or came from an official table. Applications displaying keyless rates must include a visible, followable AllRatesToday attribution link.

How it works

Add the hosted URL to an MCP client that supports remote MCP. The endpoint works without an API key for currency discovery, institution discovery, latest official tables, the latest reference table, and eligible central-bank-based lookups. It also offers a trial-key tool that issues a key limited to 100 calls over seven days; the key is adopted for the current session and can then be placed in client configuration.

With a key, live mid-market tools can query a broader set of currency pairs, compare one source against several targets, and request historical or point-in-time data according to the account plan. When a client supports authorization headers, send the key as a bearer token. A URL query parameter is available for clients that only accept credentials in the endpoint URL, but that form can expose the key through configuration files, logs, or screenshots.

The hosted endpoint is a Streamable HTTP MCP service. The package also has a separate stdio form, which clients launch as a subprocess through npx or a global npm installation.

Setup and configuration

Use the following endpoint in a remote-MCP client:

text
https://allratestoday.com/api/mcp

Claude Code can add it with:

Terminal
claude mcp add --transport http allratestoday https://allratestoday.com/api/mcp

For authenticated access, configure ALLRATES_API_KEY where the client supports environment variables, or pass Authorization: Bearer <key>. Registering at AllRatesToday provides a lasting key; the server also supports the in-session trial-key flow.

Tools and capabilities

The core exchange-rate tools include:

  • get_exchange_rate for one current fiat pair.
  • get_historical_rates for 1-day, 7-day, 30-day, or 1-year windows ending now, with period-specific sampling.
  • get_rates_authenticated for multiple targets or a specified historical time and bucket.
  • list_currencies for supported codes, names, and symbols.
  • list_central_banks for institution codes and publication metadata.
  • get_official_rates for the latest or dated table from a named institution.
  • get_reference_rate for the daily, never-revised reference table.
  • request_trial_key for a temporary API key.

The hosted service also lists additional central-bank functions from the related server, including official-rate history, rate comparisons, and publication-calendar access.

Limitations and notes

This service handles fiat currencies; it does not provide cryptocurrency or commodity rates. get_exchange_rate does not perform arithmetic on user-supplied amounts. Keyless exchange-rate results may be official central-bank values rather than live market quotes, and some currency crosses are unavailable without a key. Historical series, point-in-time lookups, and dated official or reference tables require a paid plan. Always relay the returned rate_date, and choose official or reference data when compliance, accounting, or reproducibility matters instead of treating a live mid-market quote as an official rate.

Frequently Asked Questions about AllRatesToday exchange rates (hosted)

AllRatesToday exchange rates (hosted) is an MCP server that connects AI clients to the AllRatesToday API through a hosted Streamable HTTP endpoint. Its main tools retrieve live, historical, official, and reference fiat rates, list currencies and institutions, query multiple targets, and request a trial API key.

You do not need to install the hosted service. Add `https://allratestoday.com/api/mcp` to an MCP client that supports remote MCP; Claude Code can use `claude mcp add --transport http allratestoday https://allratestoday.com/api/mcp`.

No, several tools work without a key, including currency and central-bank discovery, latest official tables, the latest reference table, and eligible official-rate lookups. A key enables broader live rates, while historical and dated queries require a paid plan.

It works with remote-MCP clients including Claude.ai, Claude Desktop, ChatGPT, Cursor, VS Code, Codex, and Gemini CLI. The package also supports stdio clients such as Claude Code and Windsurf, along with other MCP-compatible hosts.
