What is the Nws Claude MCP MCP server?

Nws Claude MCP MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. A Model Context Protocol (MCP) server that integrates the US National Weather Service API with Claude Desktop, providing real-time weather data and forecasts directly within your Claude conversations.

What you get

  • Real-time weather conditions and forecasts
  • Location-based weather queries using coordinates or place names
  • Seamless integration with Claude Desktop via MCP
  • Live data from the official US National Weather Service API
  • Detailed weather metrics including temperature, humidity, wind, and precipitation

Configuration and credentials

  • Claude Desktop App - Python (v3.12 or higher) - uv package manager - Internet connection for API access

Setting it up

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

Choosing this one

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by shreyyzsh; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the nws claude mcp mcp server does with a few real requests.
