Claude Jenkins MCP: Connect Jenkins to Claude
Yes. Add the Carly connector to Claude, connect Jenkins, and you can set up triggers right from the chat: when this happens in Jenkins, do that. “When a build fails on main, text whoever is on call and open a Jira ticket with the log.” You type it once in Claude. Carly does it every time, whether Claude is open or not.
Where Claude and Jenkins fall short today
Jenkins has an official MCP server plugin. Here’s what people are reporting on its tracker:
- Builds run with the wrong parameters. Two bugs opened October 20, 2026, say triggering a build through the plugin drops or ignores some parameters, so the build runs with defaults.
- Auth isn’t what you set. One open report says tool calls run as anonymous despite valid credentials.
- No way to stop a build. Cancel and abort are still a feature request.
- Security patching. A 2026 advisory, CVE-2026-57300, covered a missing permission check fixed in plugin 0.178.0.
- It only answers when asked. The plugin responds to Claude’s questions. A failed build at 2am stays quiet until someone opens a chat.
How Carly fixes it
- Two minutes to set up. Add the Carly connector, connect Jenkins in Carly, done. No plugin to install or patch.
- Triggers. Carly acts the moment a build fails, passes or hangs, and on any schedule you set.
- It tells the right people. Carly texts the on-call, posts to Slack, opens the Jira ticket and emails the client.
- Everything else. Carly connects to thousands of apps, including GitHub, Bitbucket, Jira, Slack and PagerDuty.

- “When a deploy job finishes, post the result to #releases in Slack.”
- “When a build has been running for over an hour, ping me.”
- “Every morning at 9, send me last night’s failed jobs.”
- “When the release job passes, email Claire at Databricks the release notes.”

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
