Questions

Does ChatGPT support MCP servers?
Yes, remote servers only on the web: a public HTTPS address using Streamable HTTP, or a private server through Secure MCP Tunnel, added from the Plugins page. The ChatGPT desktop app shares Codex's configuration file.
Does ChatGPT support skills?
Yes. Standalone skills work in the ChatGPT desktop app, and skills that come inside plugins work on the web, desktop and mobile. You call a skill with @.
