The New MCP Roadmap

> With the 2026-07-28 release, a remote MCP server is now no different from any other HTTP workload

Good. Introducing a bespoke new protocol was one of the more bone-headed things MCP did on initial release.

I still struggle to see how a MCP endpoint is easier for agents to work with compared with a REST endpoint and a skills.md file.

I am very curious how many MCP servers will actually implement all of this:

"MCP authorization today is built around a person approving access in a browser. That works well for interactive clients, but more and more of the callers are agents running as cloud workloads with their own identity, acting on behalf of a user who isn’t present, or delegating narrower authority to sub-agents. We want MCP servers to have a standardized way to recognize and trust those agent identities, built on existing standards rather than pasted API keys and long-lived tokens.

The work here covers finalizing Demonstrating Proof of Possession (DPoP) and driving its adoption, and defining an opinionated path for agent identity and delegation through Workload Identity Federation, the ID-JAG grant behind Enterprise-Managed Authorization, and standard token exchange. We will also continue to grow our engagement with the OAuth standards bodies, including the IETF OAuth and WIMSE working groups, to help the underlying standards evolve with the building blocks that agent identity needs."

When I see "MCP" I still translate that to Master Control Program.

In v.1 making MCP stateful was such a deployment-unfriendly way to do it - you need a complicated persistence layer for it to work.

All while it is just a fancy way make your OpenSchema PAI visible to AI.

> We’re starting a progressive discovery effort so a server can offer a small entry point and reveal more of its catalog as the conversation narrows.

Kind of late to the party. I've had to implement lazy loading of mcps in a couple of harnesses now but am moving to implement everything as code mode instead.

This reminds me of the actor model[1]

Half the battle is just knowing this exists

Sometimes I really respect senior developers. When specs change, you obviously have to update existing work too. Looking at this MCP change, it seems like it's becoming stateless—I'm already wondering how to adapt.

Senior programmers always advised me to only use things that have been around for at least three years. Now I finally understand why.
