WordPress MCP Server

A Model Context Protocol (MCP) server for WordPress integration, compatible with Windows, macOS, and Linux.

Overview

This MCP server enables interaction with WordPress sites through the WordPress REST API. It provides tools for creating, retrieving, and updating posts using JSON-RPC 2.0 protocol.

Installation

  1. Clone the repository
  2. Install dependencies:
npm install
  1. Build the project:
npm run build

Configuration

Add the server to your MCP settings file with environment variables for WordPress credentials:

{
  "mcpServers": {
    "wordpress": {

        "WORDPRESS_USERNAME": "your-username",
        "WORDPRESS_PASSWORD": "your-app-password"
      }
    }
  }
}

The environment variables are:

You can also provide these credentials in the request parameters if you prefer not to use environment variables.
