Does Buffer Have an MCP Server?
Short answer: no. As of 2026, Buffer has no native MCP server. Socialync does, so Claude, ChatGPT, and any AI agent can post to your social accounts for you.
The short version
Buffer shipped a public API, an MCP server and a CLI on 27 May 2026, and made it free on every plan including the free tier. Setup runs through Claude Connectors in about three steps.
Socialync is the one social scheduler built with a native MCP server. You generate a key, paste it into your AI assistant, and it can draft, schedule, and publish across every platform you have connected. That is the gap this page is about.

Where Socialync fits
Buffer is a clean, well-loved scheduler that pioneered the queue, and its MCP server is genuinely free. The trade-off is Buffer per-channel pricing, which climbs with every account you add. Socialync bundles a set of accounts into its base plan and publishes to eight platforms from one connection.
