Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"zippopotam": {
"url": "https://gateway.pipeworx.io/zippopotam/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 250+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"

ask_pipeworx({ question: "your question about Zippopotam data" })
The gateway picks the right tool and fills the arguments automatically.
