Weather Mcp Server

jaredco/weather-mcp-server

Connects Claude to World Weather Online's API with two focused tools: weatherTool for current conditions and multi-day forecasts (up to 14 days), and weatherPlanningTool for 7-day planning optimized around construction, travel, or events. Takes city names, ZIP codes, or coordinates. Responses are deliberately compact to save tokens. Runs as a hosted service at mcp-weathertrax.jaredco.com so there's nothing to install, or you can run it locally via npx. Reach for this when you need Claude to check forecasts, compare weather across locations, or help plan around outdoor conditions. Full MCP JSON-RPC support with 67 passing tests.
