What Is MCP? A Plain-English Guide for WordPress Users

Spend ten minutes in any Bricks Builder community right now and you will keep bumping into the same three letters: MCP. Bricks 2.4 supports it. AI tools advertise it. Vendors, us included, sell products built on it. What almost nobody does is stop and explain it in plain English, so this article does exactly that. No code, and every technical term gets defined the moment it shows up.

Full disclosure before we start: we at Bricksfusion build and sell an MCP for Bricks, so we are not neutral bystanders. The explanation below stays vendor-neutral, and we will flag the one place where it stops being neutral.

What is MCP, actually?

MCP stands for Model Context Protocol. It is an open standard: a set of published rules anyone can build on for free, the way PDF is a standard for documents. Anthropic, the company behind the Claude AI assistant, created it in late 2024. Since then it has been adopted across the software industry.

Here is the problem it solves. An AI chat app on its own can only talk. It can tell you how to build a pricing section in Bricks, but you still do the clicking, the copying, and the pasting. MCP gives the AI a way to operate other software directly: the software publishes a menu of actions it allows (called "tools"), and the AI can read that menu, pick an action, and run it.

Two bits of jargon are worth learning because you will see them everywhere. The AI app you chat with (Claude Desktop, Claude Code, Cursor) is called the client. The software offering the actions, your WordPress site for example, is called the server. Ignore the physical-machine associations; "server" here just means "the side serving up the tools."

Just as important is what MCP is not. It is not an AI, it contains no intelligence, and it does not make Claude smarter. It is plumbing: one standardized cable between AI apps and other software, where every connection used to be custom-built. Anthropic itself compares it to USB-C, one port that fits everything, and that is the best analogy we have heard.

Why do WordPress and Bricks users suddenly care?

Because in 2026 that cable reached page builders. Two things happened at once.

First, Bricks 2.4 (in beta as of July 2026) shipped native MCP support. Your Bricks site can now act as an MCP server, exposing roughly 145 actions an AI can perform: creating elements, editing templates, changing theme styles, and much more. We unpacked the whole catalog in our plain-English guide to the Bricks 2.4 AI features.

Second, tool vendors, including us at Bricksfusion, started offering their own MCPs alongside the native one. Same idea, same AI clients, but each vendor exposes different, more specialized tools. That competition is the not-so-neutral part of this story, and it is also why the term suddenly appears on every product page, including ours.

For you, the practical change is this: the same Claude window where you draft emails can now open your site and build the pricing section itself. That is the difference between advice and labor, and it is why the excitement is louder than the usual AI noise.

What can an AI actually do through MCP?

Exactly what the connected server allows: no more, no less. The AI cannot see your screen, browse your admin area, or wander outside its toolbox. Connected to a Bricks site, the toolbox typically covers three kinds of work:

• Reading. Listing your pages and reading what is on them, so the AI knows what exists before it changes anything.
• Building. Creating new sections and editing existing ones: headings, layouts, styles, the actual content of your pages.
• Managing. Working with templates and other site-level pieces, depending on which tools the server offers.

In practice it feels like a conversation. You type: "Add a three-column features section under the hero on the homepage." Claude calls a read tool to see the page, then a write tool to create the section, and reports back, each step visible in the chat. A few seconds later the section exists in Bricks, made of real elements you can edit normally.

We ran exactly this experiment against the native Bricks 2.4 connection and published the unedited results. Short version: genuinely usable structure, with real gaps in design consistency.

What could go wrong?

The important question, because MCP gives an AI write access: the ability to change things, not just read them. Four habits keep that power boring, in the good sense:

• Use a staging site. A staging site is a private copy of your site used for testing; most hosts can create one in a click or two. While Bricks 2.4 is in beta, let the AI loose on staging, not on the site your visitors see.
• Know your undo button. Bricks 2.4 automatically saves a restorable revision when an AI edits your pages and elements. That is a genuinely good piece of safety design: if the AI overwrites the wrong section, you roll it back. Site-wide data like classes and variables is not revision-tracked, though. Practice one restore before you need it.
• Treat credentials like passwords. Every MCP connection is authorized by a credential (an application password or a private URL, depending on the route). Anyone who holds it can edit your site. Don't paste it into tools you don't trust, and revoke it when an experiment ends.
• Expect confident mistakes. AI errors are not malicious, just statistical: a button with no link, a color that ignores your palette. Review what it builds the way you would review a new freelancer's work.

What should you try first?

1. Create a staging copy of your site, or spin up a throwaway test install. Every experiment below happens there.
2. Pick a connection route. There are two options: the native Bricks 2.4 MCP (free with your license, technical setup) and our Bricksfusion MCP (paid, paste-one-URL setup). We wrote a step-by-step guide to both, traps included.
3. Start with read-only requests. "List my pages" or "describe the structure of my homepage" cannot break anything, and it teaches you how the conversation flows.
4. Then build one small section on a staging page, inspect every color and link it wrote, and restore the revision once for practice.

The promoted version of this story is that AI now builds websites while you sip coffee. The real version, as of July 2026: it is a fast, capable assistant that needs supervision, and MCP is simply the cable that plugged it into WordPress. Understand the cable, set the guardrails, and it is well worth trying.
