Check an Article's Performance

Use `get_post_stats` to pull key metrics for any piece of Substack content. You get the read count, engagement rate, and top-performing date range. It’s great for figuring out what kind of topics actually keep people reading. Just feed it a post ID and you've got the hard numbers.

Map Out Your Audience

The `list_subscribers` tool pulls your current list of subscribers into Claude. You can analyze who signed up, how many people are paid versus free, and spot any weird trends in your audience growth. This is the fastest way to get a clear snapshot of your user base without exporting anything manually.

Gather Publication Details

Need basic info about the Substack publication itself? `get_publication_info` gives you the official name, description, and overall status. It’s perfect for verifying details before a launch. This helps your agent build out metadata or verify credentials when building a new landing page.
