Starwell: World Data & Statistics
Statistics from 28 agencies: FRED, Eurostat, ECB, World Bank, OECD. Cited values, computed answers.The vendor's description, from its MCP Registry listing.
- Warning: Some tools have no description, so an AI has to guess what they do.
Nothing failed, but there is something to know or fix. 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

- YesConnected in 157 ms.
- Sign-up?
- None neededIt answered without any account or key.
- Can it change things?
- YesSome tools say they can change things. Your AI client should ask you first.
