Tools for your AI Agents to operate OpenWeather
Ask your AI agent "What's the current weather in São Paulo?" and get the answer without opening a single dashboard. With 11 tools connected to real OpenWeather data, your agents reason over live information, cross-reference it with other MCP servers, and deliver insights you would spend hours assembling manually.
Works with Claude, ChatGPT, Cursor, and any MCP-compatible client. Powered by the Vinkius - your credentials never touch the AI model, every request is auditable. Connect in under two minutes.
