CircleCI

The CircleCI MCP Server is a remote server hosted by CircleCI that connects Claude directly to your CI/CD pipelines, giving you a conversational interface to the same pipeline, workflow, job, and artifact data you'd normally reach through the CircleCI CLI or dashboard. With this connector, you can ask Claude to check the latest pipeline status for a project or roll back a deployment - all without leaving your conversation. When something breaks, Claude can pull the failure logs for a specific build and help you understand what went wrong, or dig into test results for a job to pinpoint which tests failed and why. Beyond troubleshooting individual runs, the server supports broader pipeline health and efficiency work. Claude can identify underused resource classes to help you right-size compute and control costs, and list artifacts produced by your builds so you can retrieve build outputs without hunting through the UI. It also helps with day-to-day project management: checking component versions across your fleet, and pulling usage data for cost and consumption analysis. For configuration work, it can act as a config helper - assisting with validating and troubleshooting your .circleci/config.yml setup. In short, this MCP Server turns Claude into a working partner for CI/CD: monitoring pipeline health, debugging build and test failures, managing releases and rollbacks, and keeping an eye on cost and reliability - all through natural conversation rather than manual dashboard digging or CLI commands.
