About Posterly

Posterly is a hosted scheduler that supports 18 social platforms. You can create posts in a dashboard, or write them with ChatGPT, Claude, Gemini, Cursor and other AI tools and connect those tools to Posterly through MCP so they can schedule and publish on your behalf. Every post remains visible in the dashboard.

The MCP flow is built around approval: an assistant drafts captions in your brand voice, validates the post, and then waits, with scheduling gated until you approve, edit or deny. The same capabilities are available through an API reference and a command line tool.

There is also an agency area covering content plans, client approvals and a brand visual adapter, plus guides for connecting several AI assistants. Pricing is listed as a Starter plan with API access from $10 per month, and users can sign in with Google.
