In January 2026, Chris Boyle developed a foundational MCP Server Tool within the vercel/ai repository, enabling remote Model Context Protocol connectivity for xAI’s Responses API. He implemented end-to-end support for both streaming and non-streaming MCP calls, including argument transformation and event streaming, using TypeScript and full stack development skills. The tool introduced a new factory for configuring remote MCP servers, supporting flexible integration through customizable options and authorization. Chris validated the solution in a Next.js application, updated documentation and tests, and exported the tool for SDK-wide use, ultimately expanding xAI’s ability to interact with external MCP services.
