Find the Right Climate Data

This tool connects Claude to the NCDC's historical climate database. Before you pull any data, you can ask your agent to explore what's available. It's a good way to figure out exactly what you need. Use `list_data_categories` to see broad types like 'Temperature' or 'Precipitation', then use `list_data_types` to get specific metrics like 'Max Temperature' or 'Snowfall'. Your agent will show you the options right in the chat. This MCP Server makes data discovery part of the conversation.

Locate Any Weather Station

You can't get data without a station ID. Instead of searching the NCDC website, just ask your agent to find it for you. This saves a ton of time. Start with `list_location_categories` (like 'City' or 'State'), then `list_locations` to pick a specific city, and finally `list_stations` to get all weather stations in that area. Your agent chains these commands to pinpoint the exact station you need.

Pull Decades of Records with Claude Desktop

Once you have a station ID, the real work begins. The `get_climate_data` tool pulls the actual historical records for that station. You can request specific date ranges, from a single month to many years of data. Claude gets the data as a structured response, not a messy file. You can then ask it to summarize the data, find trends, or reformat it. It all happens inside your chat window.

Common questions about NCDC Climate Data Online MCP in Claude Desktop

Connect this MCP Server in your Claude Desktop settings. Then, just ask your agent in plain English, like "Find the weather station in Central Park, NY" or "Get monthly average temperatures for station GHCND:USW00094728 for 2023."

Yes. Your agent uses the `list_locations` and `list_stations` tools to find the right station ID. You don't need to know the ID beforehand; you can ask it to find a station by city or county.

You can access a wide range of historical data types, including temperature, precipitation, snowfall, and more. Use the `list_data_types` tool to ask your agent for a full list of what's available for a given dataset.

The NCDC API has rate limits, but this server is designed for research queries. You can pull data spanning several years, but requesting decades of daily data in a single query might be slow or hit limits. It's best to pull data in targeted chunks.

Your queries for NCDC climate data are sent to the Vinkius-managed MCP server, which runs in an ephemeral, zero-trust sandbox. The server only handles NCDC station metadata and historical climate records. Vinkius manages the authentication, so your local Claude configuration stays separate.
