概览

AI 生成的概览

只读 MCP 服务器，让助手从美国财政部每日数据源获取当前与历史的国债收益率、短期国库券利率和 TIPS 实际收益率。

可以做什么
  • 获取今日或 1990 年以来任意日期的国债平价收益率曲线，含日变动、月变动、10y-2y 与 10y-3m 利差及倒挂标记
  • 查询单一收益率在两个日期之间的历史，返回起止值、变动、最高、最低、均值及每日或抽样表格
  • 获取 4 至 52 周短期国库券的每日利率，包括银行贴现率和等效票息收益率
  • 读取 5 至 30 年期 TIPS 实际收益率，并给出同期限名义收益率与隐含盈亏平衡通胀率
  • 以结构化 JSON 加纯文本摘要返回结果，并附带 as_of 与来源字段
适用场景
适合回答依赖当前或指定日期国债市场数据、模型本身无法知道的问题，例如今日 10 年期收益率、收益率曲线是否倒挂、短期国库券利率或盈亏平衡通胀率，也适合做短周期收益率历史对比。
运行要求
需要远程 streamable HTTP 端点，无需令牌或注册。由于未发布 npm 包，README 另说明可用 Node 20 或更高版本从仓库本地构建 stdio 版本。需要能访问财政部数据源的网络。
安装前请注意
所有工具均标注为只读，且不要求任何凭据。数据为最近拍卖证券的财政部平价收益率，而非盘中市场报价；冷启动请求可能需 15 至 20 秒。单次调用历史最多 731 天，结果中会链接到第三方页面。

README

treasury-yields-rates-today-mcp

Treasury yields and rates today for AI assistants. Ask for the 10-year Treasury yield, whether the yield curve is inverted, what T-bills pay or where breakeven inflation sits, and get the U.S. Treasury's own daily numbers.

This is a Model Context Protocol (MCP) server. It reads the U.S. Department of the Treasury daily interest rate XML feed at call time and needs no API key.

Tools

ToolWhat it returns
treasury_yield_curveThe par yield curve from 1 month to 30 years for today or any date back to 1990, with the change from the previous business day and a month earlier, and the 10y-2y and 10y-3m spreads with an inversion flag.
treasury_yield_historyOne yield (10y, 2y, 3m, 30y and others) between two dates, up to 731 days per call: start, end, change, high, low, average and a table.
treasury_bill_ratesDaily bill rates for 4 to 52 week bills: bank discount rate and coupon-equivalent yield.
treasury_real_yieldsTIPS real yields for 5 to 30 years with the nominal yield and breakeven inflation.

Every result has structured JSON, a plain-text summary, as_of, source and more (a page on mcpstamp.com). Every tool is marked read-only.

What it knows that your model does not

  • Today's yields. Treasury publishes new rates after about 3:30 pm ET every business day.
  • Whether a date was a holiday or weekend: the server answers with the business day before and says so.
  • The spread and inversion arithmetic in basis points.

Example prompts

  • "What is the 10-year Treasury yield today?"
  • "Is the yield curve inverted right now?"

Limitations

  • Treasury par yields on the most recently auctioned securities, not market quotes during the day.
  • The feed can take 15 to 20 seconds to answer a cold request. The hosted server caches the current month for an hour and closed months for a week.
  • History is limited to 731 days per call.
