How posting from your AI works
Add the server URL
Point Claude, ChatGPT, Cursor, or any MCP client at https://mcp.socialync.io/mcp. Sign in with your Socialync account in the browser and pick which brands the assistant may manage. No keys to copy.
Or use an API key
Clients that cannot open a browser (Grok Bot, headless agents, hand-edited config files) use an API key from Socialync settings as a Bearer token instead. One key per brand, revocable any time.
Post in plain English
Tell your AI what to publish. Drafts route to your approval queue by default, or flip on direct publish when you trust the workflow.
