概览

AI 生成的概览

远程 MCP 服务器，让助手通过付费的 currencylayer 账户查询实时与历史汇率并换算金额。

可以做什么
  • 获取最多 174 种货币及贵金属相对基准货币的实时汇率
  • 查询某个过去日期的汇率，最早可回溯至 1999 年
  • 按实时或历史汇率在两种货币之间换算金额
  • 获取最长 365 天区间内逐日汇率
  • 对比两个日期的汇率，给出绝对变化与百分比变化
  • 查看当月用量、提交功能请求、升级或取消订阅
适用场景
适合在对话中需要汇率或货币换算的场景，例如按其他货币报价、查询某个历史日期的汇率，或了解某货币对在一段时间内的走势。适合已有 currencylayer 账户并接受按量计费付费服务的用户。
运行要求
远程端点，仅需添加 URL；客户端配置中不要放 API 密钥或 Authorization 头。通过 OAuth 登录，登录页会要求填写 currencylayer 凭据。需要 currencylayer 账户及套餐：免费版每月 50 次工具调用，货币换算需 Basic 及以上套餐，日期区间需 Enterprise 及以上套餐。
安装前请注意
每次调用汇率工具都会消耗一次月度配额，即使认证后失败也照常扣除。付费套餐通过升级工具返回的 Stripe Checkout 链接付款，取消后当期不退款。README 将汇率工具标为 write 类型并建议客户端确认，尽管它们只读取汇率。currencylayer 凭据需在该服务器的登录页输入。

安装

在 SourceWeft 中

  1. 打开 控制台中的 currencylayer MCP by usefulapi，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

README

currencylayer MCP by usefulapi

Read and calculate exchange rates with your paid currencylayer account.

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://currencylayer.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http currencylayer https://currencylayer.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "currencylayer": {      "url": "https://currencylayer.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your currencylayer credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/currencylayer/

工具

5

currencylayer_get_live_rates

Get live exchange rates

SPENDS 1 request of your currencylayer monthly quota per call (also when it fails after authentication; it is never retried). Real-time exchange rates for up to 174 world currencies and precious metals relative to a source currency (default USD). Quotes are keyed by pair, e.g. USDEUR = 0.918 means 1 USD = 0.918 EUR. The free plan refreshes daily, higher plans hourly down to every 60 seconds. Use 'currencies' to limit the reply. GET /live.

输入参数sourcecurrencies

currencylayer_get_historical_rates

Get historical exchange rates

SPENDS 1 request of your currencylayer monthly quota per call (also when it fails after authentication; it is never retried). Exchange rates for one past date (data back to 1999 for most currencies; a currency added later has no data before its start date and the whole request then fails). Quotes are keyed by pair, e.g. USDEUR. Use 'currencies' to limit the reply. GET /historical.

输入参数date必填sourcecurrencies

currencylayer_convert_currency

Convert an amount

SPENDS 1 request of your currencylayer monthly quota per call (also when it fails after authentication; it is never retried). Convert an amount from one currency to another with real-time rates, or with the rates of a past date. Returns the result and the quote used. Needs the Basic plan or higher. GET /convert.

输入参数to必填datefrom必填amount必填

currencylayer_get_timeframe_rates

Get exchange rates for a date range

SPENDS 1 request of your currencylayer monthly quota per call (also when it fails after authentication; it is never retried). Daily exchange rates for every date from start_date to end_date (at most 365 days apart), one entry per date. Needs the Enterprise plan or higher. The reply must stay small: days x currencies may not exceed 2000 (without 'currencies' that is 174 per day), checked before the request is sent. GET /timeframe.

输入参数sourceend_date必填currenciesstart_date必填

currencylayer_get_rate_changes

Get exchange rate changes

SPENDS 1 request of your currencylayer monthly quota per call (also when it fails after authentication; it is never retried). How exchange rates changed between two dates: per currency pair the start_rate, end_rate, absolute change and change_pct. Pass both dates or none (none = yesterday's end-of-day rate against the latest rate). Forex markets are closed on weekends, so a weekend change can be zero. Needs the Enterprise+ plan or higher. GET /change.

输入参数sourceend_datecurrenciesstart_date
