we removed a toggle from chatgpt! no, not that one. but, you no longer need to toggle developer mode to connect custom MCP servers! all users can now just go to plugins → add → create custom MCP server to connect MCP servers.

Announcing one more launch: ChatGPT Sites can now host MCP servers, including plugin extensions! 🤯 > @⁠sites create a todo list that I can use in ChatGPT This will: · Create an MCP server with extensions · Deploy that MCP server to Sites · Turn the MCP server into a plugin · Install the plugin for you across web, mobile, and desktop ChatGPT is slowly becoming malleable software that anybody can customize to their needs. Very excited to see what you all build with this!

One more launch today: the new MCP Events spec is now supported in ChatGPT 🎉 MCP servers can now push real-time updates (messages, comments, status changes, whatever) to ChatGPT, triggering automations for your users 🤯 It’s easy to add to your MCP server, too! Just point Codex at the docs and let it rip:

Starting today, you can connect multiple accounts with most plugins in ChatGPT! 🎉 Bring context from your work and personal accounts into the same conversation. Connect your accounts in the plugin directory: Devs: this works automatically, with no changes needed. But, to make the experience for users of your plugin even better, add a profile tool to your MCP server so ChatGPT can label the accounts:

what do you think is the probability that AI will have caused one enormous positive outcome for humanity in the next 10 years? (e.g. eliminate poverty, solve climate change, find cures for many known diseases,… really enormous)

total MCP victory, some quick misc thoughts about why MCP is so much better than CLIs: - indexable tool catalog letting agents scale to unlimited tools - no requirements to be running a full sandbox - consistent auth across all MCPs rather than each CLI inventing its own auth - multi account support for all MCPs unlike CLIs - implementations like code mode let the model know what will be returned allowing for super efficient token usage unlike CLIs the reasons it took this long for MCPs to finally have their moment is mostly due to bad MCP implementations in clients: - you had to restart your whole client to use an mcp (no hot reloading) - agents weren't as familiar with debugging mcps as they were CLIs, so it was a lot easier for people to get set up using them but over the past year, things like codex and claude plugins have all been using MCP under the hood, i.e computer use is an MCP, i believe claude artifacts are an MCP app, just the silent steady adoption there is still an element of MCPs that is 'this MCP could've been an OpenAPI spec' but that'll go away as things like triggers get more adoption at the end of the day, what's important to realize is while yes there are these difference between CLIs / MCPs / etc they're all just different ways of doing tool calling, and you can do some combination of lazy loading, searchable tools, and filtering to build efficient harnesses

codex is all you need! i've had a codex check all new listings across redfin, zillow, realtor in my area for the last many months and it's worked great. - use the chrome extension and browser use so it uses your actual browser and accounts - tell it to keep a running log of what it's already seen - set up hark @ryanvogel to notify you when it finds a great fit - whenever it notify's you, look at the listing and immediately give the agent feedback about it to learn "like this, but this is a no-go, bla bla"

Get more out of GPT-6 Astra by revisiting your skills, AGENTS.md, and task prompts. Make skill triggers specific, load guidance when it's relevant, and define what done looks like.

Astra has officially made it to the nether fortress in our long-horizon Minecraft computer use eval. Something no AI has done in history. It is now in the final stretches of beating the game in real time.

AI should make the tools you already love more useful. ChatGPT's new Data agent works with Snowflake, Databricks, Tableau, Hex, and 30+ other tools through plugins. Proud of our team and partners for making this work excellently across so many tools!

I get asked a lot 'how should I build an MCP server?' or 'should i build an MCP or a CLI?', glad to see someone finally doing it right excellent example of what to do and how here by Andre w/ Neon, putting a cleaner layer on top of their openapi spec and making that accessible
