Show HN: Meteosource MCP server, weather data for AI assistants

Two values, and the agent is online #

The server speaks the Model Context Protocol over Streamable HTTP. Every client needs the same two things: the address and your Meteosource API key in a header. The plan the key is on decides which tools the agent sees.

1. Get a Meteosource API key Sign up atmeteosource.com ; the free plan is enough to try the forecast tools.
2. Add the server in your client Addresshttps://mcp.meteosource.com/mcp , transport Streamable HTTP.
3. Add the headerAuthorization: Bearer YOUR_METEOSOURCE_API_KEY . Clients with a plain API-key field can sendX-API-Key instead.
4. Ask about the weather The agent picks the right tools itself, from place lookup to forecast.

No OAuth, no sign-in.

The key travels in a request header, is used only to call Meteosource on your behalf and is never stored in full. Caches are kept per key.

        Step-by-step setup for Claude Code, Claude Desktop and claude.ai, Codex, Antigravity and other
        clients, including team setups that keep the key out of version control, is in the
