GDP Data Skill

Overview

GDP API provides comprehensive economic data from the World Bank including GDP in current USD, GDP growth rate, and GDP per capita. Query the latest data or retrieve data for a specific year for economic analysis and research. With changes=true every reading is set against the country's own stored history: whether GDP rose or fell for every plan, and on paid plans the previous year, its GDP and real growth rate, the change in dollars and percent, the per-capita change, a growth trend (accelerating, slowing or steady), the 5-year average real growth rate, and the 5- and 10-year compound annual growth rates of nominal GDP.

The tool

Once your client is connected to the VerveKit server, this appears in its tool list as GDPDataSkill. It is read-only and open-world — it fetches and never mutates anything on your side — so most clients call it without asking you to confirm.

{
  "name": "GDPDataSkill",
  "arguments": {
    "country": "US"
  }
}

You do not name the tool yourself; the model picks it. Asking about US in the terms this skill covers is enough for it to reach for GDPDataSkill on its own — naming it explicitly also works, and is the way to force the call.

Connecting

One server URL covers every skill in the catalog, including this one. Authorization is OAuth: the client opens a browser once, and there is no key to paste into a config file.

{
  "mcpServers": {
    "vervekit": {
      "url": "https://api.vervekit.com/v1/mcp"
    }
  }
}

Per-client setup — Claude, Cursor, VS Code, ChatGPT — is on the MCP setup page.

Arguments

These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made. Premium arguments are accepted on every plan but only take effect on plans that include them.

What the model gets back

The result carries a structuredContent object matching the tool's declared outputSchema, so a client reads fields without parsing prose. status is "ok" and error is null on success; a null field means the value was not available for that input, not that the call failed.

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Failure modes

Errors come back as tool errors carrying a sentence the model can act on, not a bare status code. Error handling covers the full list.

A call costs 2 credits each time the tool actually runs; a model that reasons about the tool without calling it costs nothing.

Use cases

To assess national debt sustainability, credit rating agencies compare a government's outstanding obligations against total economic output and per capita income.
