GitLab Duo: A Smarter AI-Powered DevSecOps with Multi-Agent and MCP

Introducing GitLab Duo: A Multi-Agent AI Platform Powered by the Model Control Plane

GitLab continues to pioneer the future of DevSecOps with the introduction of GitLab Duo, an innovative multi-agent platform enhanced by the power of GitLab’s Model Control Plane (MCP). Designed to offer intelligent, streamlined, and secure development workflows, GitLab Duo brings together a suite of AI agents specialised across development stages—such as planning, documentation, code generation, testing, and security.

At the heart of GitLab Duo lies the Model Control Plane, which enables flexible integration of various AI foundation models — including both proprietary and open-source models from providers like Google and Anthropic as well as GitLab’s own optimised versions. With MCP, GitLab empowers organisations to govern AI behaviour and output more granularly, offering observability, compliance, and security across workflows.

This structured approach allows GitLab Duo’s specialist agents to work collaboratively across the DevSecOps lifecycle. For example, a Code Generation Agent can work in tandem with a Testing Agent to ensure generated code aligns with requirements and is automatically vetted through AI-assisted unit tests. These agents are woven into the GitLab platform with ergonomic UX integrations, enabling users to take full advantage of AI while maintaining operational control.

The initial GitLab Duo offering primarily supports code suggestions for GitLab SaaS customers, but additional capabilities across code refactoring, test generation, vulnerability explanation, and planning are in various stages of deployment. Large organisations especially benefit from this extensible architecture by integrating their own custom-built agents or fine-tuned models into existing workflows—while meeting regulatory, data residency, and security demands.

GitLab’s AI roadmap doesn’t just stop at Duo—it is paving the way for even more sophisticated agent cooperation and user customisation. By offering pre-built agents with responsible AI practices and giving enterprises the tools to extend this landscape, GitLab reinforces its leadership in AI-driven DevSecOps transformation.

Organisations in Czech Republic, Slovakia, Croatia, Serbia, Slovenia, North Macedonia, United Kingdom and beyond can now explore industry-leading GitLab Duo integration.
