Over a three-month period, contributed to the modelcontextprotocol/ext-apps repository by building features that enhanced media playback, mobile usability, and authentication flows. Developed audio session handling for a sheet music app, enabling background playback and seamless integration with iOS controls using JavaScript and audio API integration. Improved mobile user experience by refining iframe auto-resize logic and responsive design with CSS and TypeScript, addressing layout stability and touch interactions. Delivered an on-demand OAuth capability through a Lazy-Auth Server, implementing OAuth 2.0 flows, PKCE, and security best practices for backend development. Work emphasized maintainability, security, and cross-platform user experience throughout each deliverable.

Jun 1, 2026June 2026 (modelcontextprotocol/ext-apps) delivered a functional on-demand OAuth capability via a Lazy-Auth Server for MCP Apps. The feature enables listing and discovery of tools without upfront authentication and prompts for authorization only when a protected tool is accessed. The work includes an embedded mock authorization server and TTL-scoped token endpoints, enabling end-to-end flow in a single process. Security hardening was implemented by enforcing PKCE and redirect_uri binding in token exchanges, plus single-use authorization codes with in-memory replay protection. Additional enhancements include support for RFC 8707 resource indicators and URL elicitation tooling to illustrate flexible authorization contexts. This deliverable accelerates MCP App onboarding, reduces friction for developers, and provides a robust, testable reference implementation for on-demand OAuth in the MCP ecosystem. Key technologies/skills demonstrated include OAuth 2.0 flows (PKCE, authorization_code), token lifecycle management (TTL tokens, refresh, revocation), in-memory state tracking (jti), RFC 6749/6749-/RFC 8707 alignment, and embedded service orchestration for end-to-end testing.
