First-party MCP at server.feedboss.ai/api/v1/mcp, hosted by the vendor, plus a FeedBoss plugin in ChatGPT's plugin store. Add it as a custom connector in Claude, Cursor or another MCP app and approve access on a FeedBoss consent screen, with no API key to paste. Assistants can draft posts in your voice, check them for slop, make brand images, read analytics and your knowledge base, and schedule posts to your personal LinkedIn profile after you approve the time and account; nothing publishes on the spot. It needs a paid plan (Creator, Pro or Studio) and is not part of the free trial; writing a post uses 5 credits and a brand image 25.
