Guía para crear servidores MCP (Model Context Protocol) de alta calidad que permitan a los LLMs interactuar con servicios externos mediante herramientas bien diseñadas. Úsalo al construir servidores MCP para integrar APIs o servicios externos, ya sea en Python (FastMCP) o Node/TypeScript (MCP SDK).
composiohq/mcp-builder es una guía completa para desarrolladores que desean construir servidores MCP (Model Context Protocol) de alta calidad. MCP permite que los modelos de lenguaje grandes (LLMs) interactúen con servicios externos a través de herramientas bien definidas. Esta habilidad es fundamental para quienes necesitan exponer APIs o servicios externos como herramientas que los LLMs puedan invocar, ya sea en entornos de desarrollo locales o en producción. La guía cubre aspectos clave como la definición de herramientas y recursos, la gestión de sesiones y seguridad, y la implementación en Python usando el framework FastMCP o en Node/TypeScript usando el MCP SDK oficial de Anthropic. También proporciona patrones y mejores prácticas para garantizar que los servidores sean robustos, eficientes y fáciles de mantener. Es compatible con plataformas como Composer (de Codex), Cursor y otros agentes de IA que soporten el protocolo MCP. Al seguir esta guía, los desarrolladores pueden crear herramientas que los LLMs entiendan y utilicen de manera intuitiva, maximizando la utilidad de sus agentes de IA.
