PostFast
Connects Claude to the PostFast API for scheduling and managing social media posts across 11 platforms including Instagram, TikTok, LinkedIn, YouTube, and Pinterest. You get tools to list connected accounts, create batch posts (up to 15 at once), upload media files, delete scheduled content, and pull analytics for published posts. Each platform has specific controls like Instagram's publish type (timeline/story/reel), TikTok's privacy settings, or YouTube's playlist assignment. The upload_media tool handles the full flow from local file to usable media key in one call. Useful when you want to orchestrate social posting workflows through AI assistants instead of logging into PostFast's dashboard or writing custom API integration code.

PostFast MCP Server
MCP server for the PostFast API — schedule and manage social media posts via AI tools like Claude, Cursor, VS Code, and more.

Add it as a remote/streamable-HTTP MCP server in any client that supports OAuth (e.g. ChatGPT, Claude). You'll be prompted to sign in to PostFast and authorize access on first use.
Want to run the server yourself instead? Use the npx + API-key setup in Quick Start below.
