Vibe coded a WebUI using Kiro.dev, starts on port 8080 by default:

💯 This looks really cool. I'll be testing it out this week

Adding my initial notes (not finished reviewing yet):

1. UI works very well for development mode (which is what most individuals would use).
2. Doesn't work with production mode right now (which is designed for enterprise use cases).
   In prod mode, the client first needs to authenticate with mcpjungle using their access token. So a quick solution will be to allow the user to enter their access token when they open the UI. The UI can then open up the "admin" dashboard.
3. Kiro.dev seems to be in Preview mode, so looks like an early-stage product (I personally don't have access to it). So mcpjungle cannot heavily rely on it yet. The prompts provided as part of .kiro/ seem general-purpose though, so I think they can also be used with other products like Kiro if required.
