get_follower_history
Daily follower-count history for an account (current count + delta over a date range) — Facebook Pages, Instagram, YouTube, Pinterest, Threads, Bluesky, Telegram, LinkedIn (company pages), TikTok
How to use it
Project documentation lists get_follower_history for the Postfast MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
