Pluginfree

Weather MCP is a free, open-source MCP server that gives AI assistants like Claude 17 weather tools — one-call summaries, forecasts, alerts, air quality, marine and lightning data, and historical records back to 1940 — built entirely on free public APIs with no signup or API key required. It's for developers who want to add real weather data to an AI assistant or agent without setting up and paying for a commercial weather API.
