Live weather and air quality (GAIA)
Weather, air quality and nearest live sensors anywhere, each with a signed receipt. Free, no key.The vendor's description, from its MCP Registry listing.
Every public check ran and passed. Public audit: we connect as an AI client would, list the tools and check what they say. We do not run them. How we audit
