Which of the following are items on the MCP 2026 roadmap?

Quick reference

TL;DR

The 2026 roadmap targets real 2025 pain: multi-agent coordination, tool versioning against rug pulls, smoother OAuth, and observability hooks. Fine-tuning and mandatory sandboxing are out of scope.

Easy to grasp

Imagine a city that grew too fast. The first year, everyone just plugged power strips in wherever they could. By year two the planners write a roadmap for the real problems: a directory so you can find the right outlet, electrician licensing so a swapped fixture cannot secretly rewire your house, better key cards for restricted rooms, and meters so you can see what is drawing power. They do NOT promise to redesign the appliances themselves, and they do NOT force every building to wall off its own rooms, that stays each owner's job. The MCP roadmap is the same. It fixes discovery, trust, auth, and visibility, the things that hurt in production. It leaves model training and execution isolation outside the protocol.

Everything important, quickly.

5 min: name the four real roadmap themes, tie each to a 2025 production failure, then defend why fine-tuning and mandatory sandboxing fail the protocol-scope test.

Side-by-side

Roadmap item	On roadmap?	Why
Multi-agent coordination primitives	Yes	Standardizes agent delegation, a documented 2025 gap
Tool versioning	Yes	Structural defense against rug pull attacks
Improved OAuth UX	Yes	Smooths painful remote-server onboarding
Observability hooks	Yes	Trace spans plus error classification for production
Model fine-tuning hooks	No	Training is outside a wire protocol's scope
Mandatory sandboxing enforcement	No	A protocol cannot enforce host runtime isolation

Real-world examples

Real products, models, and research that use this idea.

Rug pull defense matters when a registry server like mcp.so updates a tool definition after a host already approved the older version.
Observability hooks let teams running MCP servers in production wire trace spans into Datadog or OpenTelemetry and classify JSON-RPC errors.
OAuth 2.1 onboarding friction hit teams exposing remote MCP servers behind enterprise identity providers like Okta in 2025.
Multi-agent coordination overlaps with protocols like A2A, which the 2026 roadmap positions as complementary rather than competing.
