Buffer MCP server & Claude connector

Does Buffer have an official MCP server or Claude connector?

Official

As of October 2026, Buffer documents an official remote MCP server at mcp.buffer.com/mcp on its developer site. Claude connects with OAuth, while other clients use an API key as a Bearer token. It can list, create, edit and delete posts, so review actions before approving. No public source repo was found.
