These connect in one click. Vistazo runs the servers, handles the upstream APIs, and keeps them current — you need no account, no key, and no setup. They are a good way to see the whole product work before wiring up anything of your own, and several are genuinely useful alongside your own data. Pulling exchange rates or a macro indicator next to your revenue is a normal thing to want.

Connecting one

Settings → Connections, pick it from the list, done. There is no authorization step of your own to complete — you are authorizing Vistazo’s connection to a public API, not an account.

Using them from your own agent

Each is a separate MCP endpoint, so your own agent can connect them directly rather than going through Vistazo:
They sit behind Vistazo’s authorization server, so a connected agent signs in as you. See Connect an agent.

Attribution and licensing

The upstream data is not ours, and its licenses require credit. Each connection’s detail page carries the attribution, and it is reproduced on the tool reference pages linked above:
  • World Bank Open Data (CC BY 4.0)
  • Open-Meteo.com (CC BY 4.0)
  • SEC EDGAR, U.S. Securities and Exchange Commission
  • U.S. Treasury Fiscal Data API

Calls to these sources are metered like any other data call, and each is rate-limited per source. See Usage and Limits.
