MCP Bootcamp: Connect Claude to Everything
MCP Bootcamp: Connect Claude to Everything Live workshop · Oct 31 – Nov 1, 2026
This bootcamp is for developers and technical builders who want Claude to do more than write text. In two live sessions you set up MCP in Claude Code and Cursor, connect Claude.ai connectors, build a small server of your own, and learn how to check a server before you trust it. You finish with a safe setup guide your team can reuse.
What you can do: Use code MCP20 at checkout to take 20% off a single seat. The first live session is this Saturday.
