Claude Code and GitLab: Three workflows that ship

This post details three workflows integrating Claude Code with GitLab for accelerated software development and shipping. The first workflow demonstrates fixing a C++ bug using Claude Code, followed by GitLab CI/CD, security scanning, and Duo Code Review. The second workflow enhances Claude Code's context by integrating the GitLab Model Context Protocol (MCP) server, allowing it to access GitLab issues, merge requests, and other SDLC data. The third workflow showcases using a Claude-powered external agent within the Duo Agent Platform to address code review feedback directly in a merge request. It also covers prerequisites and setup for these workflows, including configuring Claude Code, the GitLab MCP server, and preparing a GitLab project.
