Ask for a post
Tell Cascade what to post, where and when. It checks your channels, writes the post (or a separate version per network) and schedules it. Every post shows up in your Postbase calendar.
https://mcp.postbase.so/mcpWhat to ask Windsurf
Plain language works. These are a few things people ask for.
“Write a launch post for X and Bluesky about what we built today and schedule it for 9am.”
“Turn the README's feature list into a LinkedIn post and save it as a draft.”
“What's going out tomorrow?”

Frequently asked questions
What can Cascade do in my Postbase account?
Four things: list your connected channels, create a draft or scheduled post (or thread), list what's queued, and cancel a scheduled post. It can't delete posts, disconnect accounts or change settings.
Which networks can Cascade post to?
Text posts and threads go to X, LinkedIn, Bluesky and Mastodon. TikTok and YouTube need a video, so for those ask for a draft and add the video in the Postbase composer before it's scheduled.
How do I stop Cascade posting for me?
Open Developers → Connected apps in Postbase and click Revoke next to Cascade. Access ends immediately, and anything already scheduled stays in your calendar for you to keep or cancel.
Do I need a paid Postbase plan?
Every plan includes the MCP server, and every plan starts with a 7-day free trial. You can also self-host the open-source version for free.
