CircleCI MCP Server
The official CircleCI MCP server lets AI agents work with your CircleCI CI/CD pipelines. Agents can fetch build-failure logs, find flaky tests, validate config files, run and rerun pipelines, trigger rollbacks, read the latest pipeline status and test results, list artifacts and followed projects, and analyze usage for cost.
