      "value": "mcp-pinot is a Python-based Model Context Protocol (MCP) server for interacting with Apache Pinot. In versions 3.0.1 and below, mcp-pinot defaults to running an HTTP MCP server bound to 0.0.0.0:8080 with no authentication enabled. All MCP tools, including SQL query execution, schema creation, and table-config mutation, are reachable by any network-adjacent caller. The server proxies these calls using server-side Pinot credentials, producing a confused-deputy condition that yields full read/write access to the configured Pinot cluster. This issue has been fixed in version 3.1.0"

      "value": "mcp-pinot es un servidor de Protocolo de Contexto de Modelo (MCP) basado en Python para interactuar con Apache Pinot. En las versiones 3.0.1 e inferiores, mcp-pinot por defecto ejecuta un servidor MCP HTTP enlazado a 0.0.0.0:8080 sin autenticación habilitada. Todas las herramientas MCP, incluyendo la ejecución de consultas SQL, la creación de esquemas y la mutación de configuración de tablas, son accesibles por cualquier llamador adyacente a la red. El servidor proxy estas llamadas usando credenciales de Pinot del lado del servidor, produciendo una condición de delegado confuso que otorga acceso completo de lectura/escritura al clúster de Pinot configurado. Este problema ha sido solucionado en la versión 3.1.0."
