UVLens for AI assistants
Ask ChatGPT, Grok Bot, Muse and other AI assistants about the UV index. UVLens gives them hourly UV forecasts for anywhere in the world and burn times for your skin type.
What you can ask
Ask in your own words. Your assistant gets the forecast from UVLens and answers in the chat.
- The UV index now, or hour by hour for any day in the forecast
- The lowest-UV time for a walk, run or other outdoor plan
- The UV for events in your calendar
- How long until unprotected skin burns, if you give your skin type
-
UVLens What's the UV like where I am today?
-
UVLens When is UV lowest for a one-hour walk tomorrow?
-
UVLens How long until I burn at midday? I'm skin type 2.
-
UVLens Check the UV for my outdoor events this week.

Questions
Is the UVLens plugin free?
Yes. The ChatGPT plugin and the MCP server are free, and you don't need a UVLens account.
Which AI assistants work with UVLens?
ChatGPT has the UVLens plugin. Grok Bot, Claude, Muse, Cursor and other assistants that support MCP connectors can use the UVLens MCP server at https://mcp.uvlens.com/mcp.
Does UVLens know my location?
No. The plugin doesn't use your device location. Your assistant sends UVLens the name or coordinates of the place you ask about. UVLens doesn't save your location or skin type.
What skin type should I give?
UVLens uses the Fitzpatrick scale, from type 1 (always burns, never tans) to type 6 (rarely or never burns). The plugin doesn't work out your skin type. To find yours, take the skin quiz in the UVLens app.
Are burn times safe exposure times?
No. A burn time is an estimate of how long until unprotected skin starts to burn. Protect your skin whenever the UV index is 3 or higher.
Where does the UV forecast come from?
The plugin uses the same hourly UV forecasts as the UVLens app and UV map. They account for cloud, ozone and the position of the sun.
