During January 2026, Shreyas Kothari developed the Experimental Extensions Framework within the modelcontextprotocol/modelcontextprotocol repository, enabling Working Groups and Interest Groups to prototype and incubate extension ideas for the Model Context Protocol before formal SEP submission. He designed a governance model and established naming conventions to clearly distinguish experimental work, ensuring a structured transition path from incubation to official protocol status. His work focused on protocol design and comprehensive documentation, using Markdown to update lifecycle processes and governance associations. The framework addressed the need for a transparent, well-documented process for experimental features, reflecting thoughtful depth in both design and implementation.
