What you can do with this MCP connector
This server lets your AI agent handle localized outdoor health checks using UV radiation metrics. You don't need a bunch of different weather sites; this is your single source for reliable environmental data.
Before you run anything, you can use the check_api_status tool to verify if the Open UV Index API connection is active and ready for service. It confirms whether the whole system is operational right now, so you don't waste cycles calling a dead endpoint. Knowing the status upfront saves time.
To get the actual measurement, your agent calls get_uv_index. This tool delivers the precise, current Ultraviolet Index reading based on any latitude and longitude pair you give it. It gives you the hard number—the risk level right now at that specific spot. You can use this data point to gauge immediate outdoor safety.
If you need to plan for tomorrow or later in the week, you'll pull data using get_uv_forecast. This tool audits the expected daily range and timing of solar intensity (UV forecast) for a location. It doesn't just give you an average; it shows you when the peak solar activity is going to hit that specific area.
Once your agent has the UV Index or the forecasted risk level, it uses get_uv_protection_guide. This tool takes that raw number and generates actionable sun safety advice. It'll tell you exactly what kind of SPF you need, if a hat is mandatory, or if sunglasses are enough based on the current risk.
You get concrete instructions, not just numbers.
These tools work together to give your agent full control over outdoor planning data. When you combine checking the status with getting real-time readings and then generating specific safety guides, your AI client acts like a specialized environmental consultant. It monitors UV levels and helps you keep track of things that matter for localized health—it's all tied back to accurate coordinates.
How Open UV Index API MCP Works
- 1 Subscribe to the server and input your OpenUV API Key.
- 2 Your AI client calls a tool (e.g.,
get_uv_index) specifying the required latitude and longitude. - 3 The service returns structured data: the current UV Index, ozone level, and the recommended safety guidance.
The bottom line is that your agent handles the coordinate input and multiple API calls so you just get a clear answer about how safe it is to be outside.
Who Is Open UV Index API MCP For?
Any professional whose job depends on knowing precise, localized environmental risk. This is for field scientists tracking radiation exposure, event planners organizing outdoor festivals, and health professionals needing immediate data validation in the field.
Uses get_uv_index and check_api_status to collect raw UV metrics and confirm continuous uptime for long-term research logging.
Calls get_uv_forecast days before an event, then uses get_uv_protection_guide during planning meetings to set up safety stations.
Uses the system on-site to check UV conditions for a group of people in real time, ensuring they have proper protection before starting an activity.
What Changes When You Connect
- Get immediate safety decisions. Instead of just seeing a number, calling
get_uv_protection_guidetells you exactly what to pack (SPF 30+, wide-brimmed hat). - Plan ahead with confidence. Use
get_uv_forecastweeks in advance to identify peak sun hours and adjust your outdoor schedule before the event even starts. - Monitor environmental factors beyond UV. The API also provides ozone levels, giving you a full picture of air quality risk alongside radiation exposure.
- Maintain continuous operations. Running
check_api_statusensures that if your safety workflow relies on this data, it won't fail unexpectedly mid-task. - Automate cross-functional reporting. Your agent can pull the real-time UV Index (
get_uv_index) and combine it with local ozone measurements in a single report for operations leads.
Real-World Use Cases
Organizing a Marathon
The event coordinator needs to know when the sun is strongest. They ask their agent to run get_uv_forecast for the start line coordinates. The agent reports that peak intensity hits at 1:00 PM, allowing staff to mandate water breaks and shade stations during that specific window.
Field Research on Pollution
A scientist needs UV data alongside ozone readings for a pollutant study. They use get_uv_index and then query the associated atmospheric data through their agent, getting both metrics in one response to correlate environmental factors.
Checking an Emergency Site
A rescue team leader needs immediate safety intel at a remote location. They run get_uv_index and immediately receive the reading (e.g., 9/10). The agent then calls get_uv_protection_guide, recommending full coverage clothing and immediate shelter.
Long-Term Event Scheduling
A park manager is planning a multi-day festival. They use get_uv_forecast for the entire week to identify days with consistently high UV risk, allowing them to schedule activities indoors or in shaded areas during peak times.
The Tradeoffs
Only checking one metric
A user calls only get_uv_index and gets a number (e.g., 8). They assume they know what to do next, but the response is incomplete.
→
Don't stop at the raw index. Always follow up by calling get_uv_protection_guide with the location data you used for get_uv_index. This ensures you get actionable advice (SPF 30+) instead of just a number.
Ignoring system status
A critical safety workflow fails because the API endpoint is temporarily down. The user doesn't realize the problem until they are in an emergency.
→
Make check_api_status the first tool call in any automated or mission-critical sequence. This verifies service uptime before you try to retrieve sensitive data.
Mixing up forecasts and real-time
A user asks for 'today's UV index' when they really mean 'the UV index three days from now.' They get the wrong time context.
→
For future planning, always use get_uv_forecast. Reserve get_uv_index only for checking conditions at this exact moment.
When It Fits, When It Doesn't
Use this API if your core concern is physical safety from solar radiation and atmospheric contamination. You need to know: 1) What the risk is right now (get_uv_index), 2) When the risk will peak (get_uv_forecast), or 3) What specific gear you need (get_uv_protection_guide).
Don't use this if your goal is general weather tracking (like rain chances, wind speed alone), or historical academic modeling that requires data from non-UV sources. For those tasks, look for a general meteorological API. If you only plan to check the status, just run check_api_status—it’s fast and confirms everything else works.
