Servidores MCP locales: stdio: de Unity MCP a V8 Cpu Profile Decoder MCP

El cliente inicia el servidor como programa en el mismo ordenador e intercambia con él mensajes JSON-RPC a través de la entrada y salida estándar. No se expone nada en la red; el programa se ejecuta con los permisos del propio usuario.
