What is the OpenWeatherMap MCP Server?

Connect OpenWeatherMap to your AI agent to get instant access to global meteorological data. Whether you're planning travel, monitoring environmental conditions, or building weather-aware automations, this server provides the precise data you need.

What you can do

Current Conditions — Get live temperature, humidity, wind speed, and weather descriptions for any city or coordinate via get_current_weather.
Extended Forecasts — Access 5-day/3-hour forecasts with get_forecast or use the One Call 3.0 API for 48-hour hourly and 8-day daily projections via get_onecall.
Air Quality Monitoring — Retrieve real-time pollution data including PM2.5, PM10, CO, and Ozone levels using get_air_pollution.
Geocoding Services — Seamlessly convert city names to coordinates with direct_geocoding and vice versa with reverse_geocoding to power location-based queries.

How it works

FAQ

Frequently asked questions

How do I get a comprehensive weather report including hourly and daily forecasts?

Use the get_onecall tool with latitude and longitude. It provides current data, 48-hour hourly forecasts, and 8-day daily forecasts in a single request.

Can I check the air quality for a specific location?

Yes, the get_air_pollution tool returns real-time data for pollutants including CO, NO2, O3, and particulate matter (PM2.5/PM10) for any coordinates.

How do I find coordinates for a city name to use with the weather tools?

Use the direct_geocoding tool. Simply provide the city name (and optionally state/country), and it will return the latitude and longitude needed for tools like get_onecall.

How does LangChain connect to MCP servers?

Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.

Which LangChain agent types work with MCP?

All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
