MCP clients authenticate through a standard OAuth 2.1 flow with the scope posteady:full. You don't manage tokens by hand — your MCP client performs the flow when you connect, and refreshes access automatically. You can revoke access anytime from your Posteady settings.

Token lifetimes:

Access token: 1 hour
Refresh token: 30 days
Authorization code: 10 minutes

See MCP Overview for how it works, then connect your app — Claude, ChatGPT, Gemini, Cursor, or other tools.

MCP connection requires the Creator plan or above.
