Test with curl

The gateway speaks JSON-RPC 2.0 over HTTP POST. You can test any pack directly from the terminal.

curl -X POST https://gateway.pipeworx.io/caniuse/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Use with the SDK

Install @pipeworx/sdk to call tools from any TypeScript/Node project.

TypeScript
import { Pipeworx } from '@pipeworx/sdk';
const px = new Pipeworx();
const result = await px.call("feature", {"name":"example"});
ask_pipeworx
// Or ask in plain English:
const answer = await px.ask("browser compatibility data for html / css / js / web api features");
