What platforms are supported by the MCP server?

All 14+ networks connected in your AutoPoster AI workspace, including LinkedIn, Twitter/X, Instagram (Posts, Reels & Carousels), TikTok, Facebook Pages & Groups, YouTube Shorts, Threads, Bluesky, and Pinterest.

Can I revoke an AI agent's access?

Yes. You can generate separate API keys per agent or developer. If a key is compromised, revoke it immediately in Workspace Settings with zero disruption to your existing social connections.
