MCP for Beginners: What It Is and Why You’d Want It
MCP (Model Context Protocol) lets AI assistants like Claude and ChatGPT directly control your WordPress site — create posts, manage products, read data, run queries — all through a chat conversation. No coding required.
This article explains what MCP is, why it’s useful, and which setup path is right for you.
What Exactly Is MCP?
Normally, you log into WordPress, click through menus, and do tasks manually. With MCP, you talk to an AI assistant and it does those tasks for you — using your live WordPress data.
| Without MCP | With MCP |
|---|---|
| Log in → Posts → Add New → write → publish | “Create a draft post titled ‘Best Coffee Shops’ with an intro paragraph” |
| WooCommerce → Products → search → edit price → save | “Update the price of all products in the ‘Sale’ category to $19.99” |
| Export → download CSV → analyze in Excel | “How many orders did I get this week compared to last week?” |
MCP is the protocol that connects AI assistants to tools like your WordPress site. AIWU provides the WordPress side of that connection.
