CircleCI ships hosted MCP for Claude, Cursor, and Codex
CircleCI’s Sept 14 hosted MCP at https://mcp.circleci.com/v1/mcp lets Claude, Cursor, Codex, and VS Code debug CI over OAuth—no local install. It exposes 24 tools for failing runs, logs, config validation, reruns, and rollbacks, and is listed in the Claude and Cursor MCP directories.
