Artificial intelligence tools are undoubtedly reshaping how developers operate. Coding assistants, AI-powered terminals, and intelligent agents have become a standard in the modern developer environment as version control and package managers. As these tools grow to become more capable, they are also growing more and more connected, reaching into codebases, cloud services and credentials, and communications on a developer’s behalf. With all of that connectivity comes a security surface that most organizations are only scraping the surface to understand.
How MCP Become Developer Infrastructure
The Model Context Protocol (MCP) saw rapid adoption as a standard for extending AI assistants with new capabilities, and is now embedded in a wide range of developer tools. . Through MCP, developers can connect with their AI tools to external services: version control platforms, project management systems, documentation repositories, and more, without writing custom integrations. Visual Studio Code, already the world’s most widely used development environment, built native MCP support directly into the editor. With a single click on an install link, a developer can add a new tool to their AI assistant’s arsenal.
That simplicity is genuinely useful. It is also, as recent research demonstrated, a meaningful security risk when the trust boundary at the center of the install flow cannot be relied upon.
The Vulnerability
The VS Code MCP install flow works through a preview dialog. When a developer clicks an install link, VS Code presents a screen showing the configuration about to be installed. The developer reviews it, presses Install, and the configuration is written to their workspace.
That dialog is the security boundary. It is the only moment a user can evaluate a configuration delivered by an external party. And it was not showing everything.
Research from the Oasis Security Research Team found that the install dialog rendered five visible…
