The title is the issue. They're just asking for group chats with Claude
A better option is to have Claude as an assistant or bot in every group chat and triggered when needed. That is just a different interface for Claude or Cowork chat with the group chat context.
Leaving aside the implementation details, the call for action here is valid since Slack is a black hole of your enterprise data and tribal knowledge and Slack is extremely restrictive. Try using Slack MCP in Claude Chat or any AI product
I’ve built such system many times. They’re basically all the same, especially if you introduce real time updates. Channels and threads are just organization strategies.
