ChatGPT and Mastodon: frequently asked questions
Can ChatGPT post to Mastodon?
Yes. Once your Mastodon account is connected in Genfeed, ChatGPT can draft, schedule, and publish Mastodon posts through the Genfeed MCP server.
Do I need a Mastodon API key?
No. You connect Mastodon in Genfeed once by signing in. ChatGPT reaches Genfeed over MCP with browser OAuth and never sees your Mastodon credentials.
Does ChatGPT publish to Mastodon without my approval?
No. Genfeed holds posts for review, and you approve before anything goes to Mastodon, unless you set up a workflow that publishes directly.
