What is the Weather API MCP server?

Current weather and 7-day forecast for any location. OpenMeteo-powered. x402 micropayment. Exposed over MCP by the weather api mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

Current weather and 7-day forecast -- temperature, humidity, wind, precipitation. Any location worldwide. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Its toolset

Everything the assistant can do here goes through one of these:

  • data_get_weather — POST

Adding it to your client

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.

When to reach for it

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. Weather API's toolset — data_get_weather — is a fair guide to whether it matches your workflow. It is maintained by Br0ski777; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Weather API's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Caveats

  • 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 weather api mcp server does with a few real requests.

Frequently asked questions

It connects Weather API to MCP-compatible AI assistants such as Claude and Cursor, exposing 1 tool (data_get_weather) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Weather API directly.
