If you run a membership site, you’ve probably seen “MCP” show up in the settings of Claude, ChatGPT or Cursor and wondered whether it’s for you. It is. You don’t need to be a developer to use one, and you don’t need to understand the plumbing. But knowing roughly how it works makes it easier to trust, and easier to ask good questions.

This post is the plain-English version. No code.

The short answer

MCP stands for Model Context Protocol. It’s an open standard that lets an AI app connect to other software and use it. Anthropic published it in late 2024, and it has since been picked up across the industry. Claude, ChatGPT and Cursor all support it.

An MCP server is the piece on the other side of that connection. It tells your AI, “here are the things you can do with me,” and then does them when asked.

Membership MCP is an MCP server for WordPress memberships. When you connect it, your AI gains a set of tools for working with your MemberPress site: looking up members, reading subscriptions and transactions, running revenue and churn reports, creating plans and coupons, setting up access rules, and more.

Think of it like a power outlet. Your AI is the appliance. It’s already smart, and you already pay for it. Membership MCP is the outlet in the wall of your membership site. Plug in, and the AI can reach things it couldn’t reach before.

Your AI was missing one thing

Out of the box, Claude or ChatGPT knows a lot about running a membership business in general. Ask it how to reduce churn and you’ll get a thoughtful answer.

But it doesn’t know anything about your business. It can’t see things like 14 members failing a payment this week, or your Annual plan growing faster than Monthly last quarter. It’s working blind.

Before MCP, the usual fix was copy and paste. Export a CSV, paste it into the chat, ask your question, then go back into WordPress and make the change yourself. It works, but it’s slow, and the AI is always looking at a stale snapshot.

An MCP connection removes that step. Your AI asks your site directly, gets current data, and can act on it when you ask.

What happens when you ask a question

Here’s a real sequence, simplified. Say you type:

Which members had a failed payment in the last 7 days?

  1. Your AI reads the tool list. When you connected Membership MCP, it received a list of tools, each with a name, a short description and the inputs it accepts. Your AI picks the one that fits your question. In this case, a failed-payment analysis tool.
  2. It makes a tool call. The request goes from your AI app through Membership MCP’s hosted relay to the plugin on your site. The relay checks that the connection is allowed, counts it as one action against your daily allowance, and signs the request so your site can tell it’s genuine.
  3. Your site does the work. The Membership MCP plugin runs the tool against MemberPress, using the WordPress account of the admin who connected the site. It writes an entry in the activity log on your site.
  4. The data comes back. The plugin returns the matching members, plans and amounts to your AI.
  5. Your AI writes the answer. It turns that data into a reply in plain English. If you follow up with “draft a friendly note to each of them,” it writes the notes itself. That part doesn’t need a tool at all.

One detail I like: the analysis tools return data, and your AI does the thinking. Membership MCP never calls an AI model of its own. You’re not paying for a second AI behind the scenes, and your conversation stays between you and the AI app you chose.

What an action is, and why it matters

Pricing is counted in actions, so it helps to know what one is.

An action is one tool call your AI makes on your site. One lookup, one report, or one change. A simple question like “how many active members do I have?” usually takes one action. A monthly summary that pulls revenue, churn and new signups might take three or four. Writing a reply, summarizing results or drafting an email doesn’t use any actions, because your AI does that on its own.

The free plan, which comes with MemberPress, includes 50 actions a day. Plus is $19 a month for 250 a day, and Power is $49 a month for 1,000. Every plan gets every tool, and the allowance resets daily. For most single-site owners, 50 a day covers a lot of everyday work. The pricing page has the details, and the docs explain how to check your usage.

Reading versus changing

Tools come in two kinds. Read tools look things up. Write tools change something on your site.

Read tools are harmless. They answer questions and that’s it.

Write tools are where we put the guardrails. When your AI wants to change something, it gets a preview first by default. Refunds, cancellations and other hard-to-undo changes always stop at that preview and wait for your approval in your AI app, and new posts and pages are saved as drafts. You can also connect a site read-only, so your AI only ever sees the read tools.

I wrote a separate post on how we keep your AI from breaking your site that goes deeper on this.

Do I need to learn the tool names?

No. This is the part people find surprising. You never name a tool. You describe the job in your own words, and your AI figures out which tools to use and in what order.

“Make everything in my Premium category members-only for the Annual plan, then check it logged out” might take several calls across a few different tools. You don’t see that complexity unless you want to. Most AI apps will show you each tool call if you expand it, which is a good way to learn what’s happening.

If you’d rather start from something that’s known to work, our playbooks are tested asks for common membership jobs. Paste one in and adjust it to your site.

How you connect one

You set it up once:

  1. Install the free Membership MCP plugin from your MemberPress Add-ons screen, or from the plugin zip if your site has no paid MemberPress license. Start free takes you to both.
  2. Activate it and click Connect. Sign in, or create your free account.
  3. Add https://mcp.membershipmcp.ai as a connector in your AI app. Each app does this a little differently, so we wrote a guide for Claude, ChatGPT and Cursor.
  4. Sign in with Google, or with your email and password, and pick your site.

Connecting more than one site to the same AI app? Use each site’s own address from its card in your account, and name each connection after its site.

After that, you just ask. The full walkthrough is in Getting started.

The takeaway

An MCP is how your AI gets hands. Without one, it can only talk about your membership business. With one, it can look at your real members and real revenue, and do the routine work for you while you watch. Membership MCP is that connection for WordPress memberships, built by the team that makes MemberPress.

If you’ve got ten minutes, connect your site and ask it who joined this week. It’s a good first question.
