 Tasks will become a foundational building block of MCP and are expected to be supported in future protocol versions. The experimental `tasks` feature in the `2025-11-25` specification served as a stopgap until the protocol's extension mechanism was available. Now that [extensions](https://modelcontextprotocol.io/extensions/overview) have been [formalized](./2133-extensions.md), moving tasks to an official extension gives the feature time to incubate and evolve based on additional real-world implementation feedback, without being constrained by the core specification's release cadence. Once the extension has stabilized and achieved broad adoption, it is intended to be promoted into the core protocol.
 
-This proposal _removes_ the version of [tasks](https://modelcontextprotocol.io/specification/2025-11-25/basic/utilities/tasks) specified in the `2025-11-25` release. It is shaped by implementation feedback since that release, and by several changes to the base protocol included in the `2026-06-30` specification:
