One addition, can be a follow up is how to configure this in the copilot CLI and claude code. It took me a while to figure it out.

How do you configure it there? I'll add that to aspire.dev? See https://github.com/microsoft/aspire.dev/pull/8

There are links to copilot CLI and claude code MCP docs in the doc already.

I don't think it's feasible to add detailed documentation for every product and keep it up to date.

Just the popular ones.

[JamesNK]

Which are popular? Which do we want details for?

VS? VS Code? Claude Code? Copilot CLI?

I think building instructions into the dashboard dialog, like we already do for VS and VS Code, would be best. We can give an exact command line to run in the dashboard. In docs we'd need to have placeholders for the URL and HTTP header token.
