MCP changes quickly. For protocol details, interface labels, and current capabilities, prefer the official documentation over any tutorial, including this one.

What was tested, and when. The exercises were built and verified against MCP Inspector 2.7.0, the MCP TypeScript SDK 1.30.0, and Zod 4.6.5, on Node.js 22.19.0 or newer. That combination negotiates an earlier protocol version than the latest published specification, which is normal while implementations catch up.

The Stanford Claude, Stanford ChatGPT Edu, and Claude Code interface observations in Modules 7 to 9 were verified on 17 September 2026. These are managed commercial products, and their labels, controls, and institutional configuration may change. Where this tutorial describes an interface, treat it as what we saw on that date rather than a permanent fact.
