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.

Up to 26,739 servers could be affected. The CEO links it to an AI tool called ARTEX, but how the attackers got in is not public.

Its model card says it beats three similar-size models on most agent tests, but every score is the lab's own and nobody has checked them independently.

This guide shows what its setup changes in your agent's settings, and why its live capture mode counts as running the program on your own computer. Its read-only analysis just opens files. **What you can do:** Before you approve any MCP server, compare your agent's settings before and after setup and note which new tools it can now call.
