My notes to my peer group on the adoption of MCP by OpenAI:

MCP 🤝 OpenAI Agents SDK

You can now connect your Model Context Protocol servers to Agents:

We’re also working on MCP support for the OpenAI API and ChatGPT desktop app—we’ll share some more news in the coming months.

This is a big deal. It means that MCP just became the de facto protocol for connecting LLMs to outside systems.

I also suspect it will increase the speed at which MCP gets past a couple of roadblocks, the biggest being its single-user paradigm which makes it hard to roll out on a hosted platform. (Stateful API calls thru stdio for the programmers here).

Today, MCP “servers” are more like plugins for Claude desktop than actual servers. You run them locally.

Soon, ChatGPT desktop users will be able to use them too.

In turn, it means at some point you’ll have users downloading and installing them on their own. That day is a little ways off: the SDKs are only for Python and Node (JavaScript) which both run great on macOS and Linux but are a royal PITA to get going on Windows. Whenever a .Net or Java SDK is released though I’d expect to see a significant uptick in user-level usage.
