Four things, the first two required for any of this catalog's features to work, the other two only if they apply to you:
- Filesystem MCP — lets Claude read, write, and edit files in folders you approve
- Windows MCP — lets Claude open apps, click, type, take screenshots, and interact with the Windows desktop itself
- Cowork VM fix (jump to it) — only needed if Cowork mode itself refuses to start on your machine
- Email/IMAP MCP (jump to it) — only needed if you're installing FTR-42 or another feature that reads or sends email
Install Filesystem and Windows MCP first — they complement each other, Filesystem handles files, Windows MCP handles everything else. Only look at the Cowork fix or the Email/IMAP setup if you actually need that specific one.
