How to Use the Substack MCP in Windsurf

Q: How can I use Substack and Windsurf together to analyze subscriber growth?

You run listsubscribers through your agent. This gives you a clean, current roster of subscribers. You can then compare that list against previous data points to calculate the exact rate of new signups.

Q: Does Windsurf allow me to check Substack's overall publishing status?

Yeah, getpublicationinfo handles that. It gives you all the core details about the entire account, not just a single post. You get the metadata needed to confirm if the publication is active and what its general parameters are.

Q: What data can I pull from Substack using Windsurf for content ideas?

You've got several angles. Use getleaderboard to see which posts performed best, or use listposts and then getpoststats on those top pieces. This tells you exactly what kind of depth keeps people reading.

Q: If I need a list of all recent Substack content for my project, how do I get it with Windsurf?

Just run listposts. That tool pulls the titles and basic info for your most recent articles. You can then feed those IDs into other tools to pull deeper data, like full post text or stats.

Q: Which type of sensitive Substack information does Windsurf touch?

The server touches subscriber data via the listsubscribers tool. This is a list of user accounts associated with the publication. It's critical to manage this data securely.

Track Performance via MCP Server

Use `get_post_stats` to pull detailed metrics for any specific piece of content. You immediately see how many people read it, what their engagement rate is, and if the topic resonated. This capability lets you understand which articles are actually working hard. It's perfect for figuring out where your best material needs more promotion or a follow-up post.

Audit Your Readership Base

The `list_subscribers` tool gives you an immediate list of who’s subscribed to the publication. You can track growth and quickly see if your outreach efforts are paying off. Better yet, combine this with `get_publication_info` to understand the overall health of the Substack account itself while mapping out your audience size.

Manage Content Flow

`list_posts` gives you a quick rundown of everything published recently. You can see the titles and dates, which is great for creating an index or cross-referencing material. When paired with `get_post`, you pull the actual text content. This lets your agent build out comparison reports or draft follow-up pieces based on past performance.

Prerequisites

Windsurf IDE installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
