MCP's new roadmap: agentic messaging, HTTP transport unification, and agent identity

The New MCP Roadmap

MCP maintainers published a roadmap for the next spec release. Five priority areas: agentic messaging primitives (server-initiated events, Tasks extension), unifying remote and local transports on Streamable HTTP, enterprise-ready agent identity via DPoP and Workload Identity Federation instead of API keys, standardizing tool result formats, and SDK DX improvements. No specific version number or timeline is disclosed.

Why it matters: Official MCP roadmap with five concrete bets that directly address agent dev pain points. HKR all hit. Not scoring higher because this is a roadmap, not a release — specs aren't shipped yet, and the post doesn't give timelines for each proposal.
