This is clever - Mastra has launched a how to build agents course as a MCP. Notes on the course.

Setup Mastra MCP + Editor

Instal an MCP capable ide - I went with Cursor: brew install --cask cursor and then the Mastra MCP: npx create-mastra@latest --default -m cursor

I installed the mastra thingamajig in a folder called mastra101.

Aside: I already have VSCode and Zed, but this is a good excuse to finally try out Cursor.

Enable the mastra MCP server by adding to mastra101/.cursor/mcp.json

{
  "mcpServers": {
    "mastra": {
      "command": "npx",
      "args": ["-y", "@mastra/mcp-docs-server@latest"]
    }
  }
}

That only took 2 minutes, but it is an artifact of mid 2025 - we would look back at this in late 2025 and say how quaint, we had to edit JSON files to tell IDEs anything! Future IDE’s i assume will have built in logic to install/run MCP servers or connect to remote ones.
