WP Engine MCP Server

This is a TypeScript implementation of an MCP server for the WP Engine API. It provides tools and resources for interacting with WP Engine accounts, sites, installs, and backups. The server supports both local (stdio) and remote (HTTP) transports.

Features

• Get account information
• Get site information
• Get install information
• Get and create backups
• Support for both local and remote MCP connections
• HTTP transport with authentication
• Comprehensive logging and error handling

Installation

1. Clone this repository

2. Install dependencies:

npm install

3. Build the server:

npm run build

Configuration

The server requires WP Engine API credentials to authenticate with the WP Engine API. You can obtain these credentials from the WP Engine Portal's API Access page: https://my.wpengine.com/api_access

Set the following environment variables:

• WP_ENGINE_API_USERNAME: Your WP Engine API username
• WP_ENGINE_API_PASSWORD: Your WP Engine API password

Usage

Local MCP Server (stdio transport)

For use with local MCP clients like Claude Desktop:

npm run start:stdio

Or with environment variables:

WP_ENGINE_API_USERNAME="your-username" WP_ENGINE_API_PASSWORD="your-password" npm run start:stdio

Remote MCP Server (HTTP transport)

For remote access via HTTP with environment variables:

WP_ENGINE_API_USERNAME=my-api-username WP_ENGINE_API_PASSWORD=my-api-password npm run start

This runs the default server (build/index.js) which supports remote transport. You can also run with custom options:

WP_ENGINE_API_USERNAME="your-username" WP_ENGINE_API_PASSWORD="your-password" node build/main.js --transport=http --port=8080 --auth-token=my-secure-token

Command Line Options

node build/main.js [options]

Options:
  -h, --help                 Show help message
  -v, --version              Show version information
  -t, --transport      Transport type (stdio, http) [default: stdio]
  -p, --port           Port for HTTP transport [default: 3000]
  -a, --auth-token    Authentication token for HTTP transport [default: wpengine-mcp-token]

MCP Settings

Local Configuration (stdio transport)

Add the following configuration to your MCP settings file:

{
  "mcpServers": {
    "wpengine": {
      "command": "node",
      "args": [
        "/path/to/wpengine-mcp-ts/build/main.js"
      ],
      "env": {
        "WP_ENGINE_API_USERNAME": "your-api-username",
        "WP_ENGINE_API_PASSWORD": "your-api-password"
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}

Remote Configuration (HTTP transport)

For remote MCP connections, you'll need to implement an HTTP MCP client or use the server as a remote service. The server exposes an HTTP endpoint at /mcp that accepts MCP protocol messages.

Example HTTP request:

curl -X POST http://localhost:3000/mcp \
  -H "Authorization: Bearer wpengine-mcp-token" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": "1",
    "method": "tools/list",
    "params": {}
  }'

Available Tools

• **create_domain** - Add a new domain to an existing install
• **update_domain** - Set an existing domain as primary or configure redirects
• **delete_domain** - Delete a specific domain for an install

Cache Management

• **purge_cache** - Purge an install's cache (object, page, cdn, or all)

SSH Key Management

• **get_ssh_keys** - Get your SSH keys
• **create_ssh_key** - Add a new SSH key
• **delete_ssh_key** - Delete an existing SSH key

Example Tool Usage

{
  "name": "get_accounts",

}

Create a new site

{
  "name": "create_site",
  "arguments": {
    "name": "My New Site",
    "account_id": "account-uuid"
  }
}

Create a new install

{
  "name": "create_install",
  "arguments": {
    "name": "mysite",
    "account_id": "account-uuid",
    "site_id": "site-uuid",

Testing

Local Testing (stdio transport)

You can test the server using the MCP inspector:

WP_ENGINE_API_USERNAME="your-api-username" WP_ENGINE_API_PASSWORD="your-api-password" npx @modelcontextprotocol/inspector build/main.js

Remote Testing (HTTP transport)

1. Start the server in HTTP mode:

WP_ENGINE_API_USERNAME="your-username" WP_ENGINE_API_PASSWORD="your-password" npm run start:http

2. In another terminal, run the test client:

node test-http-client.js

The test client will verify that the HTTP transport is working correctly and test various MCP operations.

Security Considerations

When using the HTTP transport:

1. Authentication: The server uses Bearer token authentication. Change the default token in production.

2. HTTPS: Consider using HTTPS in production environments.

3. Firewall: Restrict access to the HTTP port to trusted networks only.

4. Environment Variables: Store API credentials securely and never commit them to version control.
