Show HN: A "Course" as an MCP Server
We wanted to build a course for new Mastra devs to get started
quickly. However, we knew videos would go out of date and be more
difficult to maintain. We decided to launch our "course" as an MCP
server. This way your coding agent actually teaches the course
content to you and can help you write the code. We think this is a
really interactive way to learn. Using an editor with MCP support
(such as Cursor, Windsurf, or VSCode), your code agent will call
the appropriate MCP tools which will return context for the agent.
This context tries to instruct the agent that it should be teaching
you the content, not just doing the work for you. The course is
still pretty experimental and some models work better than others.
Code is available in the Mastra Github repo in the mcp-docs-server
package (https://github.com/mastra-
ai/mastra/tree/main/packages/mcp-d...)

| Thanks!

| I definitely remember spending time on Codecademy years ago

| How does the course actually start? I installed it for Cursor.

| Start course. It's an mcp, talk to it like an instructor.

| make a video on how to "take" this course

| There are several videos in the link that does this.
