¡Hola, developer 👋🏻! Este repositorio contiene las demos que mostré en BiznagaFest 2025 durante la charla "IA con salero: Descubre MCP Servers en Málaga". Con él podrás aprender las características principales de un servidor de este tipo.

🎬 Las Demostraciones

Tres demos progresivas que demuestran desde lo básico hasta lo avanzado:

🟢 1️⃣ Search Video — Herramienta Básica

🎯 La puerta de entrada: aprende lo fundamental de los MCP Servers

Busca videos en YouTube basándote en una consulta simple. Esta es la demo perfecta para entender cómo todo funciona bajo el capó.

Lo que aprenderás:

Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control. Replace the environment placeholders with a token scoped to the least it needs.

Questions

What is the BiznagaFest Demos MCP server?

MCP Servers en Málaga con salero

What tools does BiznagaFest Demos expose?

3 in total: 3 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is BiznagaFest Demos safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (88/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does BiznagaFest Demos need?

It reads YOUTUBE_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does BiznagaFest Demos run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as biznagafest-mcp at 1.0.0.

How current is this page?

The grade is for one exact copy of the source (2679db805d02), read on 2026-10-10. The repository is watched and re-audited when it changes.
