Frequently asked questions
Do I have to paste my API key into Codex?
No. The MCP server uses OAuth: you sign in in the browser and that is it.
Can it publish something without me seeing it?
Only if you want it to. With approval mode, every action waits for a person to approve it.
Can I try it without publishing anything real?
Yes: have it leave posts as drafts or waiting for approval, and nothing goes out until you decide.
How much does it cost?
The same as the API: you pay per connected account, after a 7-day free trial.
