The author maintains a YouTube uploader MCP server where large video uploads succeed but trigger client timeouts. His fix: implement time-bounded long polling.
While exploring alternatives he found the experimental MCP Triggers & Events extension, which thoughtfully covers event-driven architecture in MCP, but felt like overkill for a single high-latency API — so he stuck with bounded long polling. He's asking how other MCP server developers handle long-running requests.
