I can't see why Vercel is failing, but my guess is that it's an invalid link which will be fixed once we release and have the thv group reference docs.

@eleftherias Yeah it's the broken link.

To get a clean preview, you could copy over the docs/cli directory from the toolhive repo into your PR (or just the ones you need) and we can rebase/merge with the automatic PR once the release is cut.

Made a few minor inline suggestions. Some other thoughts:

• Probably worth mentioning somewhere that a server can only be part of a single group, that if you want the same MCP server available in multiple groups, you need to run multiple instances?

• Optional, but I wonder if a simple mermaid diagram in the group management guide might be useful to help illustrate the structure?

[eleftherias]

Thanks for feedback, I added a new section for the same MCP server in multiple groups.
