MCP Tasks

In depth

A Model Context Protocol extension, made first-class in the 2026-07-28 spec, that gives long-running work a proper home - builds, deployments, long agent runs, and batch jobs that do not finish inside a single request. Because the protocol's core is now stateless, Tasks is built around resumable, pollable state rather than a held-open connection, so any server instance can advance or report on a task through a shared task store. Clients support it by handling long operations through the extension's polling model.
