Give ChatGPT file storage
ChatGPT turns a custom MCP server into a plugin. Add agentdrive on the web, and ChatGPT can save files you open with a link.
Full MCP, including saving, is on Business and Enterprise/Edu. Pro can connect custom MCP servers with read and fetch only. Setup is web only.

What about ChatGPT dots?

On Pro, custom MCP is read and fetch only. save_file and delete_file change your drive, so expect them to be unavailable there.
