# Curated sources

> Five public data sources Vistazo hosts and operates for you.

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.

| Source             | Data                                                                                                              | Tool reference                            |
| ------------------ | ----------------------------------------------------------------------------------------------------------------- | ----------------------------------------- |
| **World Bank**     | Global development indicators — population, GDP, life expectancy, CO₂ and thousands more, per country and year    | [8 tools](/mcp-tools/curated-worldbank)   |
| **Weather**        | Current conditions, forecasts and historical weather anywhere on Earth, 1940 to now                               | [3 tools](/mcp-tools/curated-weather)     |
| **SEC EDGAR**      | U.S. public company financials from filings — revenue, net income, assets, over time or compared across companies | [3 tools](/mcp-tools/curated-edgar)       |
| **U.S. Treasury**  | Federal fiscal data — daily national debt, monthly spending vs. revenue, average interest rates                   | [3 tools](/mcp-tools/curated-treasury)    |
| **Exchange Rates** | Daily rates for 30+ currencies, current and historical back to 1999                                               | [3 tools](/mcp-tools/curated-frankfurter) |

## 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:

```
https://mcp.vistazo.ai/worldbank/mcp
https://mcp.vistazo.ai/weather/mcp
https://mcp.vistazo.ai/edgar/mcp
https://mcp.vistazo.ai/treasury/mcp
https://mcp.vistazo.ai/frankfurter/mcp
```

They sit behind Vistazo's authorization server, so a connected agent signs in as you. See
[Connect an agent](/mcp/connect).

## 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

<Note>
  Calls to these sources are metered like any other data call, and each is rate-limited per source. See
  [Usage](/billing/usage) and [Limits](/reference/limits).
