Español(ES) MCP vs UTCP: qué es UTCP y cuándo usar cada protocolo

UTCP protocol specification enables direct client-to-tool calls

By PulseAugur Editorial · [1 sources] ·

The Universal Tool Calling Protocol (UTCP) is an open specification for describing existing tools in a JSON format, allowing clients to call them directly via their native protocols. Unlike MCP, where an intermediate server handles API calls, UTCP enables the client to manage these interactions. UTCP defines tool descriptions, including inputs and call templates, but does not define its own messages, relying on existing protocols like HTTP. While UTCP offers a direct client-to-API approach, it shifts security responsibilities to the client, potentially introducing risks like variable injection, whereas MCP centralizes these concerns on an intermediate server.

    MCP vs UTCP: What is UTCP and When to Use Each Protocol

    <p>UTCP (Universal Tool Calling Protocol) es una especificación abierta que describe en un «manual» JSON las herramientas que ya existen, con lo que el cliente necesita para llamarlas por su protocolo nativo. La diferencia con MCP está en quién llama a la API: con MCP, un servido…
