WP Rocket MCP Server: Handling Cache and Settings with AI Tools

Turn on WP Rocket MCP Server and AI tools such as Claude clear the cache and change settings instead of you opening the admin screen. MCP is a connection standard that lets AI tools work with programs directly, and this guide covers how to connect and disconnect with an application password and the 12 abilities it opens.

For what MCP is, see the Claude MCP basics post.

1️⃣ What Is WP Rocket MCP Server?

WP Rocket MCP Server sits at the top of the [Settings → WP Rocket → Tools] tab, labeled [Connect your AI tool to WP Rocket]. There is no on/off switch, and the [How to set up MCP] button opens the help docs.

It has been included in every license since WP Rocket 3.23 (July 9, 2026), and the MCP server opens whenever WP Rocket is active. It registers 12 abilities with the Abilities API, part of WordPress core since 6.9, and the MCP Adapter is bundled in the plugin, so there is nothing else to install.

2️⃣ How to Connect WP Rocket MCP Server

The simplest way is an OAuth connection that adds your site to Claude as a custom connector; it needs only WordPress admin approval, with no password or config file. The steps are the same in claude.ai on the web and in Claude Desktop.

1. In Claude [Customize → Connectors], click [Add → Add custom connector].
2. Enter your site name as the name and [https://your-domain/wp-json/mcp/mcp-oauth-server] as the MCP server URL, then click [Continue].

3. Leave the authentication method at the detected default, click [Add], then click [Connect].
4. Click [Allow] on the WordPress authorization screen. If you are not logged in as an admin, log in first.

Once connected, the connector screen shows three tools, all set to [Needs approval] by default. A free account can create only one custom connector, so only one site can be connected; multiple sites require a Pro or Max account.

When you ask in a new chat which MCP tools are available on your site, Claude first asks [Deny · Always allow · Allow once] before using a tool.

In Claude Desktop you can also connect with an application password. Create a password in WordPress [Users → Profile → Application Passwords], and in Claude Desktop [Settings → Developer], add the entry below to the config file, then reopen the app.

{
  "mcpServers": {
    "wp-rocket-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@automattic/mcp-wordpress-remote@latest"
      ],
      "env": {
        "WP_API_URL": "https://your-domain/wp-json/mcp/mcp-adapter-default-server",
        "WP_API_USERNAME": "your-username",
        "WP_API_PASSWORD": "xxxx xxxx xxxx xxxx xxxx xxxx",
        "OAUTH_ENABLED": "false"
      }
    }
  }
}

On Windows you need Node.js because the npx command must run. To disconnect, just revoke that application password.

3️⃣ What AI Tools Can Do

WP Rocket's 12 abilities run through the three MCP tools Claude sees ([Discover Abilities], [Get Ability Info], [Execute Ability]), and they fall into three groups: settings, cache and Rocket Insights.

Changing settings works only for options on the allowlist, and the five marked [AI not allowed] in the screen below cannot be changed.

4️⃣ Examples

After connecting to testpilotweb.com, we asked Claude to [clear only the homepage cache], and the approval prompt first showed the ability to run (wp-rocket/clear-url-cache) and the URL.

When we clicked [Allow once], only the homepage cache files were deleted on the server, and the cache of other posts stayed as it was.

You can check settings by asking, without opening the admin screen; when we asked [Is Delay JavaScript execution on right now?], it answered with the setting value and the state of the exclusion list.

The first time you use it in a chat, two approval prompts for reading the ability list and descriptions appear first, and since reading abilities also go through [Execute Ability], an approval prompt appears even when reading settings.

5️⃣ Things to Watch Out For

Tasks where an AI tool changes settings or clears the cache run only after you approve them. You can revoke the application password anytime from the screen where you created it.

Cache status checks and preload estimates return results only when WP Rocket's [Preload Cache] is on.

If it will not connect, check the config file first. Common causes are a missing comma between entries, or saving without replacing the URL, username and password placeholders.
