Substack MCP. Manage posts, stats, and subs without leaving your chat.

Substack MCP Server lets your AI agent talk straight to Substack's backend. You manage your entire newsletter operation—from drafting a killer post to checking deep subscriber metrics—without ever having to touch the main web editor. It’ll let you pull audience demographics, list draft content, or run detailed analytics purely by talking to your agent."

"### Audience Tracking and Growth Reports

You wanna know who's reading your stuff? The list_subscribers tool gives you a raw report of every person subscribed to the publication. You can use that data to build out segments or check the total count at any time. For bigger picture info, get_publication_info pulls core metadata, letting you see high-level settings like what categories you're using and if you’ve set up a custom domain for your newsletter."

"### Content Workflow: From Draft to Published

Need to check what articles are sitting there waiting? The list_posts tool pulls titles, statuses, and basic details on all the recent pieces published under the account. If you need the full write-up—the actual content or a draft version—you use get_post, which fetches everything for one specific article. You can also check out how well that single piece did by calling get_post_stats.

This tool doesn't just give you a number; it retrieves detailed performance metrics, like the exact open rate and click-through rates for that post."

"### Deep Dive Analytics and Ranking

Figuring out what works is everything. The get_post_stats mechanism calculates key engagement numbers—open rates, click rates—for any specific article you point it at. You can run these checks repeatedly to spot trends or see which topics really hit home with your readers. Beyond single-post analysis, the get_leaderboard tool retrieves a leaderboard ranking, usually based on how engaged people are with certain content pieces.

This lets you instantly know what's performing best against everything else published."

"### The Workflow In Action

You don't have to jump between five different tabs to get this stuff done. You just ask your agent: 'List the titles of my last ten posts, then pull the subscriber count, and give me the open rate for the article titled The Big Shift.' It uses list_posts first, grabs the total number via list_subscribers, and hits get_post_stats all in one go.

You'll get a clean report back without any manual copy-pasting or clicking around.

If you need to see what your whole newsletter setup looks like—the overall categories, the custom domain name, and other high-level settings—you run get_publication_info. It gives you the structural data for your entire platform. This server lets you treat Substack like a database, allowing your AI client to query it just like talking to a teammate over coffee: direct, specific, and actionable.
