ChatGPT Sites Can Now Host MCP Servers, Auto-Deploying Plugins Across Platforms
OpenAIDevs · x · 2026-10-01
OpenAI's developer account amplified an announcement that ChatGPT Sites can now host MCP servers, including plugin extensions.
- A single prompt like @sites create a todo list that I can use in ChatGPT triggers the full pipeline: create an MCP server with extensions, deploy it to Sites, turn it into a plugin, and install it across web, mobile, and desktop.
- The author frames this as ChatGPT becoming malleable software that anyone can customize to their needs.
- In the replies, a user asks whether OpenAI-hosted infrastructure like Sites will eventually handle backend needs for plugin extensions, given Sam's comments about OpenAI supporting distribution while running backends remains hard.
