MCP Adapter

Part of the AI Building Blocks for WordPress initiative

Overview

• Purpose: Implement the Model Context Protocol (MCP) standard to expose WordPress abilities to AI assistants and LLMs.
• Scope: Protocol translation, transport implementation, and security controls. Builds on the Abilities API for capability discovery.
• Audience: Site administrators, AI tool developers, and anyone connecting WordPress to AI assistants.

Design Goals

1. Standards-based – Implements the open MCP protocol specification.
2. Bidirectional – WordPress as both MCP server (expose abilities) and client (connect to other tools).
3. Secure by default – Application passwords and capability-based permissions.
4. Transport flexible – Support HTTP (REST API) and stdio (WP-CLI) transports.

Architecture

• MCP Server – Exposes WordPress abilities to external AI assistants
• MCP Client – Connects WordPress to other MCP-enabled tools (future)
• Transport Layer – HTTP, stdio via WP-CLI
