AI Content Creation + Publishing
Ask Claude to write a post about your latest feature → review the draft → schedule it to LinkedIn, X, and Threads for tomorrow morning — all in a single conversation.
Batch Scheduling from Your IDE
Working in Cursor or VS Code? Ask your AI assistant to schedule a week's worth of social media content without leaving your editor. Upload screenshots, set times, pick platforms.

Use generate_connect_link to create onboarding links for your clients. They connect their social accounts, and you manage everything from your AI tool.
Frequently Asked Questions
What is MCP (Model Context Protocol)?
MCP is an open standard created by Anthropic that lets AI assistants connect to external tools and data sources. It allows tools like Claude, Cursor, and VS Code Copilot to interact with services like PostFast using natural language — no coding required.
How do I get my PostFast API key?
Log in to your PostFast dashboard, go to API in the sidebar, and generate a new key. This key is used to authenticate the MCP server with your PostFast account.
Can I schedule posts to multiple platforms at once?
Yes! The create_posts tool supports batch creation of up to 15 posts at once. You can schedule to different platforms, set different times, and include media — all in a single command using natural language.
Does the MCP server support media uploads?
Yes. The upload_media tool handles the full upload flow — it gets a signed URL, uploads your local file, and returns the media ID ready to use in your posts. Supports images and videos.
Which AI tools support MCP?
MCP is supported by Claude Desktop, Claude Code, VS Code (GitHub Copilot), Cursor, Windsurf, JetBrains IDEs (2025.1+), Cline, Zed, and many more. Any tool that supports the Model Context Protocol can use the PostFast MCP server.
Is the MCP server free to use?
The postfast-mcp npm package is free and open source. You just need an active PostFast account with an API key. PostFast offers a 7-day free trial to get started.
