Show HN: A “Course” as an MCP Server

Mastra launched an innovative MCP server-based course for developers that integrates directly into code editors like Cursor and VSCode, allowing AI agents to teach course content interactively while helping write code. The approach keeps educational material maintainable and up-to-date by leveraging MCP tools that provide context to guide agents toward teaching rather than simply completing tasks.

Key Points

• •Course delivered as an MCP (Model Context Protocol) server instead of traditional videos to avoid outdated content and reduce maintenance burden
• •AI coding agents teach course content interactively by calling MCP tools that return contextual learning material
• •Designed to guide agents toward teaching rather than simply completing tasks for users, promoting active learning
• •Compatible with MCP-supporting editors including Cursor, Windsurf, and VSCode for seamless integration
• •Course content is still experimental with variable performance across different AI models
• •Implementation available in Mastra GitHub repository under the mcp-docs-server package for community access and contribution
• •Interactive approach enables real-time code writing assistance alongside conceptual instruction
• •MCP server architecture allows course content to be dynamically updated without requiring user-side video re-downloads
