Ask your AI assistant about GDP
Connect Claude, ChatGPT, Cursor or any assistant that supports the Model Context Protocol (MCP) to worldgdp.org. It can then answer questions with our latest nowcasts, the data that moved them and their track record, instead of guessing or browsing.

Free, no account or key. Streamable HTTP transport. Fair use: 60 requests per minute per user.
Connect
- Open Settings, then Connectors.
- Choose Add custom connector.
- Name it
worldgdpand paste the address above as the URL. Leave authentication empty. - Enable it in a chat from the tools menu, then ask away.
- Open Settings, then Connectors (custom connectors may need developer mode, depending on your plan).
- Create a connector with the address above as the MCP server URL and no authentication.
- Select it in a new chat.
Run once in your terminal:
claude mcp add --transport http worldgdp https://mcp.worldgdp.org/mcpAdd to .cursor/mcp.json (or Settings → MCP → Add server):
{
"mcpServers": {
"worldgdp": { "url": "https://mcp.worldgdp.org/mcp" }
}
}
Any client that supports remote MCP servers over Streamable HTTP: use the address above. For clients that only run local servers, bridge it with mcp-remote:
{
"mcpServers": {
"worldgdp": { "command": "npx", "args": ["-y", "mcp-remote", "https://mcp.worldgdp.org/mcp"] }
}
}
Try asking
- "What is the latest world GDP nowcast, and which economies are driving it?"
- "How has the US nowcast for this quarter changed, and which data releases moved it?"
- "Compare euro area and UK growth this quarter, with their uncertainty ranges."
- "Which data releases this week could move the nowcasts?"
- "How accurate is the China model? Show its grade and version history."
What it can look up
| Tool | Returns |
|---|---|
list_economies | Every economy and region: current nowcast, 70% range, share of world GDP, accuracy grade. |
get_nowcast | One economy: headline nowcast, range, days to the official release, daily path, component contributions and the latest data releases with their impact. |
get_aggregate | World or a region: nowcast, coverage and each economy's contribution. |
get_release_calendar | Upcoming data releases feeding the nowcasts. |
get_track_record | Accuracy grade, model version history and backtest errors by horizon. |
Economies use short codes (us, cn, jp, de, fr, uk, …) and aggregates use slugs (world, europe, european-union, euro-area, north-america, …); list_economies returns the full list. Growth is % q/q at a seasonally adjusted annual rate; data refresh daily after 07:00 UTC.
