Developers on CircleCI who want an agent to investigate failing pipelines and flaky tests.

CircleCI's official MCP server surfaces pipeline, workflow, job, and test-insight data, including failed-test log retrieval, to MCP clients.

Runs locally via npx or Docker and calls the hosted CircleCI Cloud or server API.

Invoked right after a CI failure so an agent can pull logs and suggest a fix in the same session.

Closes the loop between a red build and a code fix without the developer leaving the editor.

Requires a CircleCI personal API token and project or org scoping to fetch pipeline data.

Official, maintained under the CircleCI-Public GitHub organization, open source under the MIT license; read-mostly access to build data with the token carrying whatever project permissions it was issued.
