What you can do with this MCP connector
The Weather Open-Meteo MCP Server connects your AI client directly to high-precision meteorological data for any city on Earth. You'll get real-time readings and forecasts without having to open a single external weather site.
weather.current gives you the immediate, live conditions for any location, delivering things like temperature, wind speed, and humidity right now. This tool lets your agent know what's happening on the ground at this very moment in time.
For planning ahead, weather.hourly breaks down exactly what to expect over the next 24 hours, giving you an hour-by-hour view of changing weather patterns. If you need a longer look, weather.forecast generates multi-day forecasts covering up to 14 days for whatever place you're interested in.
When your planning involves multiple places, weather.compare lets you run simultaneous comparisons across two to five different cities. It doesn't just list the readings; it calculates a comfort score based on current conditions across all those locations so you know where's goin' to be easiest to deal with. You can also use weather.best_time to scope out the next 72 hours, scoring specific times for optimal outdoor activities—whether that’s running, shooting photos, or just chilling outside.
Safety and health are handled by other tools too. If you need to know about potential dangers, weather.alerts pulls up any active weather advisories or warnings issued for a city's forecast data. For air quality checks, weather.air_quality gets the current Air Quality Index (AQI) and details specific pollutant levels like PM2.5.
This tool even spits out a health recommendation so you know what to do with that info.
This suite of tools lets your agent act as a personal meteorologist, giving you actionable data points instead of vague summaries. You can pull together current temperature readings from weather.current, combine it with the detailed pollutant breakdown from weather.air_quality, and then use that combined info to check for optimal outdoor times using weather.best_time—all in one go.
How Weather (Open-Meteo) MCP Works
- 1 First, subscribe to this server and connect it to your AI client (Claude, Cursor, etc.).
- 2 Next, ask your agent a specific weather question, referencing the location and the desired time frame (e.g., 'What's the air quality in London?').
- 3 The agent calls the appropriate tool (
weather.air_qualityorweather.forecast), receiving structured data that it uses to write a plain-English answer.
The bottom line is, your AI client handles all the complex API calling; you just ask the question in natural language.
Who Is Weather (Open-Meteo) MCP For?
Anyone who plans anything outside needs this. Think logistics managers checking routes for wind warnings, outdoor guides planning multi-day treks, or travel planners comparing destinations before booking a trip. This is essential for field operations and detailed personal scheduling.
Checks weather.forecast and weather.alerts to determine if a planned delivery route will be impacted by heavy rain or high winds.
Uses weather.best_time and weather.air_quality to adjust daily itineraries, ensuring clients have the safest window for hiking or running.
Compares multiple destinations using weather.compare so a client can choose where they'll actually enjoy their trip.
What Changes When You Connect
- Know if an activity is actually possible. Instead of guessing, run
weather.best_timeto score the next 72 hours and find the optimal window for hiking or cycling in any city. - Manage health risks immediately. Use
weather.air_qualityto check local AQI levels; it tells you if pollutants like PM2.5 make outdoor activity unsafe right now. - Compare destinations instantly. Need to pick between Miami and New York? Run
weather.compareto see side-by-side conditions and a comfort score for both locations. - Plan routes with confidence. Check
weather.alertsbefore sending teams out; the tool flags active warnings like severe storms or high UV levels, so you don't miss critical safety info. - Get minute-by-minute detail. For today, use
weather.hourlyto track expected changes over the next 24 hours—it’s better than a simple daily average.
Real-World Use Cases
Planning an Outdoor Event
You're organizing a charity race in Denver. Instead of checking general forecasts, you use weather.best_time to pinpoint the best 3-hour window over the next 72 hours for running. The agent reports back with a score and specific tip, letting you set the perfect start time.
Trip Comparison
A client wants to visit Paris or Rome this weekend. You run weather.compare on both cities. The agent immediately flags which city has better current conditions and a higher comfort score, saving you the back-and-forth emails.
Checking Pollution Safety
You're advising someone with asthma about an upcoming trip to Beijing. You run weather.air_quality for that date, and the agent immediately alerts you to high PM2.5 levels, recommending they reschedule or take precautions.
Field Operations Check
A delivery team needs to cross a region with variable weather. You use weather.forecast for the next 14 days and review the hourly details using weather.hourly for the specific day, ensuring they know when heavy rain is expected.
The Tradeoffs
Using Current data for a trip
Asking 'What's the weather in Miami?' and getting only today’s conditions. This gives you no idea if it'll be rainy three days from now.
→
For future planning, always use weather.forecast to get the full multi-day outlook. If you need granular detail for tomorrow, run weather.hourly instead.
Ignoring Air Quality
Simply checking temperature and thinking it’s a good day. You miss out on dangerous levels of pollution that make outdoor activity unsafe.
→
Always pair your weather checks with weather.air_quality. The tool gives you the health recommendation, making sure the conditions are safe for sensitive groups.
Comparing only two cities
Asking 'Should I go to London or Berlin?' but missing out on comparing them against a third option like Amsterdam. You miss the best possible choice.
→
Use weather.compare and list all three (or more) destinations in one prompt. It computes a comfort score for every city, guiding you to the true winner.
When It Fits, When It Doesn't
You should use this server if your core problem involves predicting when or where an outdoor activity can safely happen. The key decision point is time resolution: If you need today's exact conditions hour-by-hour, use weather.hourly. If you need a general idea for the next two weeks, use weather.forecast (up to 14 days). Don't use weather.current if you are planning anything beyond the immediate moment—it only gives you what's happening right now. Use weather.compare specifically when your decision hinges on picking between two or more locations. If your main concern is health risk, always check weather.air_quality; it provides a specific health recommendation that temperature alone cannot give.

Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This server provides 7 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.
Available Capabilities
Relying solely on general weather reports for planning trips is exhausting.
Right now, checking the forecast means opening three tabs: one for daily temps, one for hourly wind speed, and a third to see if there are any severe alerts. You end up cross-referencing data points—is it windy *and* raining? Is that bad enough to cancel the trip? It's a manual mess of copy-pasting and comparing disparate numbers.
With this MCP server, your agent handles the logic. Instead of just dumping raw data, you ask: 'Should we hike tomorrow?' The agent runs multiple tools—checking `weather.best_time`, then pulling in air quality from `weather.air_quality`—and gives one clear answer with all the necessary details.
Weather (Open-Meteo) MCP Server: Compare City Weather Conditions
Before, comparing two cities required manually looking up each location on separate weather sites. You’d check the temperature in New York, then switch tabs to see if London was also warm enough, often missing subtle differences like wind direction or humidity levels.
Now, you just ask your agent to compare them. The tool executes `weather.compare`, giving you a single side-by-side view with calculated comfort scores. It tells you exactly which city is better right now—no clicking required.
Common Questions About Weather (Open-Meteo) MCP
How do I get the air quality forecast using weather.air_quality? +
The weather.air_quality tool gives current AQI readings and health recommendations for a city, but it doesn't predict future pollution levels. For general forecasts, use weather.forecast; for detailed daily air quality checks, you may need to check the provider's documentation.
Can I compare more than two cities with weather.compare? +
Yes. The tool accepts and compares up to five different city names at once. This is useful for big group travel planning or logistics route assessment.
Should I use weather.forecast or weather.hourly for a 24-hour period? +
Use weather.hourly. While weather.forecast gives you the general daily trend, weather.hourly provides the specific, hour-by-hour breakdown of expected conditions for the next day.
What is the best use case for weather.best_time? +
weather.best_time finds the optimal window in the next 72 hours based on your activity type (running, cycling, etc.). It gives you a scored recommendation and a specific tip to make planning easier.
Is an API key required to run tools like weather.current? +
No, you don't need an API key for non-commercial use; just connect your AI agent directly through the MCP client. Vinkius handles the connection and access credentials for you.
For multi-day planning, what’s the difference between using weather.forecast versus weather.hourly? +
Use weather.forecast when you need a long-term look spanning 1–14 days. Only use weather.hourly if you require an hour-by-hour breakdown covering the next 24 hours.
If I use weather.compare, how does the system handle conflicting or misspelled city names? +
The tool accepts natural language place names and attempts to geocode them automatically. To ensure accuracy, always provide full context, like 'city, state' (e.g., 'Boston, MA').
What types of conditions does the weather.alerts tool report? +
This tool reports active advisories derived from both current data and the 7-day forecast. If no significant severe weather warnings are detected for a city, it returns an empty list.
Do I need an API key to use this weather server? +
No. This server uses the Open-Meteo API, which is free and open-source for non-commercial use. You can start using it immediately without any manual configuration or signup processes.
Can I check the air quality for my city? +
Yes. The weather.air_quality tool provides the current US AQI level, concentrations of PM2.5, PM10, Ozone, and health recommendations based on the current conditions.
How can I find the best time for a run or a hike? +
Use the weather.best_time tool. You can specify your preferred temperature range and whether you want to avoid rain. Your agent will analyze the forecast and suggest the optimal time windows for your activity.
