The 221-comment thread also warns Opus 5 will act on open Jira tickets without being asked, and settles on one rule, enable only the MCPs you actively use.
Why now: The thread was live with 221 comments as of August 31.
A 368-upvote r/ClaudeAI thread asked which Claude MCP connections pay off, and among 221 replies, Jira and Confluence top the list.
The risk is real. Commenters say connecting Opus 5 to Jira can make it act on tickets nobody asked it to touch. Anyone linking an agent to a live company ticket queue should know that going in.
After Jira and Confluence, the next tier is Home Assistant, Notion, and Figma. For dev and ops work, commenters point to Datadog, Grafana, and Playwright. Several recommend Playwright's CLI over its MCP, since the MCP costs more tokens for the same result.
The biggest theme in the thread is custom tooling. The MCPs people rely on tend to be built for one person's own stack, not the popular ones everyone installs. The closing advice, repeated across the comments, is to turn on only what you're using right now and cut the rest. I've seen the same conclusion in the String paper, reached by trial and error rather than intuition.
