In April 2026, RL developed a progress-based timeout management feature for the modelcontextprotocol/ext-apps repository, focusing on improving reliability for long-running server interactions. Using Node.js and TypeScript in a full stack context, RL introduced a mechanism where hosts can interpose user-interactive or extended steps between guest tool calls and server responses without triggering premature timeouts. The implementation leveraged progress tokens and per-request timeout resets on progress notifications, enabling heartbeat-driven workflows and reducing user-visible orchestration errors. This approach preserved existing caller overrides while enhancing extensibility, demonstrating thoughtful engineering depth in addressing the challenges of robust server-client communication for complex workflows.
