Cómo conectar

Añade el servidor a la configuración de tu cliente MCP. Claude Desktop, Cursor y la mayoría de los demás clientes leen este formato:

{
  "mcpServers": {
    "ucash-pay": {
      "type": "http",
      "url": "https://mcp.u.cash/"
    }
  }
}

Cada línea es algo que un programa encontró al buscar: la entrada del registro, la respuesta del propio servidor, una especificación que se puede leer. Si falta una línea, es que no la encontramos, no que no exista.
