Our World in Data MCP — curated indicators + raw chart data, no auth.

Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.

Tools

• list_popular_indicators(category?) — curated catalog of high-signal slugs.

• fetch_indicator(slug, country?, since_year?, until_year?, limit?) — tidy long-format data for one indicator.

• get_indicator_metadata(slug) — title, units, source, last updated.

Related MCP server: mcp-un-sdg

Data source

https://ourworldindata.org/grapher/<slug>.csv and .metadata.json — public, no key required.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "owid": {
      "url": "https://gateway.pipeworx.io/owid/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Owid data" })

The gateway picks the right tool and fills the arguments automatically.
