SAN FRANCISCO, CA — August 8, 2025 — Coplay, the AI copilot for game developers, today announced several major milestones as it continues to grow its influence in the AI-for-games ecosystem. The company has taken over as the official maintainer of the most widely used open-source Unity Model Context Protocol (MCP) server, introduced key product updates like Orchestrator Mode, and opened public beta access to a growing developer base. These developments mark a new chapter for Coplay as it delivers on its mission to bring agentic workflows and AI automation to the heart of game development.
Originally created by Unity VR developer and content creator Justin Barnett, the open-source Unity MCP server has become a staple in the Unity and AI developer communities. As interest surged, maintaining the repo became a full-time job that Coplay has officially stepped in to support.
“We’ve admired what Justin built with Unity MCP and how the community has rallied around it,” said Jos van der Westhuizen, CEO and Co-founder of Coplay. “By stepping in as its official steward, we’re helping ensure that Unity developers have a reliable and continually improving gateway to AI-powered workflows, whether they use Coplay or not.”
Justin Barnett has also joined Coplay to help advance both the open-source MCP project and Coplay’s own product roadmap, ensuring the best of both worlds for developers.
As part of its 2025 roadmap, Coplay has now opened its public beta to all developers. Previously invite-only, Coplay’s platform is now being both large AAA studios and fast-moving indie teams. Already, Coplay is completing over 3,000 Unity development features per week for users via natural language commands and AI orchestration.
Recent feature updates include:
- Orchestrator Mode: Enables developers to execute multi-step tasks in sequence, based on a single game design document or command.
- Expanded AI integrations: New image generation and 3D model support help streamline the asset pipeline.
- Agentic task execution: Agents can now perform long-running or asynchronous workflows directly within Unity.

With its open-source involvement and AI automation platform working in tandem, Coplay is well positioned to lead the next wave of innovation in game development. As tools like Unity MCP bring AI agents closer to mainstream workflows, Coplay ensures they’re practical and powerful.
“We’re not just building a feature, we’re building a new interface for how creative software should work,” said Westhuizen. “By removing friction and giving developers real agency through AI, we’re unlocking a new era of game creation.”
