已验证Streamable HTTP可网页运行位置与生活

概览

AI 生成的概览

远程 MCP 服务器，让助手按美国邮编或城市实时查询 EPA/NWS 的紫外线指数预报。

可以做什么
  • 按美国邮编或城市与州查询当日紫外线指数，含 EPA 等级、防晒建议、紫外线警报状态、小时峰值及紫外线达 3 及以上的时段
  • 获取按当地时间的逐小时紫外线预报，含每小时 EPA 等级、峰值时段与防护时段
  • 解释紫外线指数在 EPA 量表上的含义、对应的 EPA 建议以及 NWS 紫外线警报规则，无需联网
适用场景
适合回答关于美国某地今日紫外线强度、最适合或最安全的户外时段、防晒时机，以及当地是否发布紫外线警报的问题——这些实时数值无法从模型训练数据中获得。
运行要求
需要一个远程 streamable HTTP 端点；无需 API 密钥、令牌或注册。服务器在调用时访问 EPA Envirofacts 紫外线指数服务，因此需要网络连接。仅覆盖美国邮编和城市。
安装前请注意
仅做只读查询，不涉及账号、凭据或写入操作。结果为预报，云量、海拔、积雪、沙地和水面都会改变实际暴露。当 EPA 无该地预报或服务不可用时，工具会返回错误而非凭记忆给出的数值。

安装

在 SourceWeft 中

  1. 打开 控制台中的 UV Index Today MCP，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。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/io.github.theluckystrike%2Fuv-index-today-mcp/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

README

uv-index-today-mcp

Today's UV Index for AI assistants, by US ZIP code or city, read live from the EPA UV Index forecast that the National Weather Service issues each day.

This is a Model Context Protocol (MCP) server. It calls the EPA Envirofacts UV Index service at call time. It needs no API key.

Tools

ToolWhat it returns
get_uv_index_todayToday's UV Index for a ZIP code or city and state, the EPA category and sun protection advice, whether a UV Alert is in effect, the hourly peak and the local hours when UV is 3 or higher.
get_uv_index_hourlyHour by hour UV Index forecast in the local time of the place, each hour with its EPA band, plus the peak hour and the protection window.
explain_uv_indexWhat a UV Index number means on the EPA scale and the EPA advice for it, plus the NWS UV Alert rule. Works offline.

Every result has structured JSON, a one-paragraph summary, as_of, source (the exact EPA request) and more (a page on mcpstamp.com).

What it knows that your model does not

  • Today's UV Index for your ZIP code. It changes every day with season, cloud cover and ozone, so a model's training data cannot know it.
  • The hour when the sun is strongest today and the hours when EPA says protection is needed.
  • Whether NWS and EPA have issued a UV Alert for the place today.

Cursor

Add to ~/.cursor/mcp.json:

{  "mcpServers": {    "uv-index": { "url": "https://uv-index-today-mcp.lipmichal.workers.dev/mcp" }  }}

VS Code

Add to .vscode/mcp.json:

json
{  "servers": {    "uv-index": { "type": "http", "url": "https://uv-index-today-mcp.lipmichal.workers.dev/mcp" }  }}

Local stdio (after npm release)

The npm package is not published yet. After it is, run it locally with Node 20 or newer:

claude mcp add uv-index -- npx -y uv-index-today-mcp

Example prompts

  • "What is the UV index today in 33101?"
  • "When is the UV highest in Phoenix today, and when do I need sunscreen?"
  • "Is there a UV alert for Denver today?"
  • "Is a UV index of 7 high?"

Data sources

Full list with fetch dates in DATA_SOURCES.md.

Limitations

  • US ZIP codes and cities only. EPA does not cover every small town by name. Use the ZIP code or the nearest larger city.
  • These are forecasts. Clouds, altitude, snow, sand and water change the real exposure.
  • Hourly times are local time for the place, as EPA publishes them.
  • When EPA is down or has no forecast for a place, the tool returns a clear error instead of a remembered number.
