WordPress MCP Adapter
MCPWordPress's official plugin that turns abilities registered through the Abilities API into MCP tools, resources and prompts, reachable locally over WP-CLI (STDIO) or over HTTP. Needs WordPress 6.9+; abilities are private by default and must be exposed manually.
MCP Adapter
Part of the AI Building Blocks for WordPress initiative
The official WordPress package for MCP integration that exposes WordPress abilities as Model Context Protocol (MCP) tools, resources, and prompts for AI agents.
Overview
MCP Adapter bridges WordPress's Abilities API with the MCP specification, giving AI agents a standardized way to interact with WordPress functionality. It includes HTTP and STDIO transport support, comprehensive error handling, and an extensible architecture for custom integrations.
Features
- Ability-to-MCP conversion — WordPress abilities automatically become MCP tools, resources, and prompts
- Multi-server management — run multiple MCP servers, each with its own transports, abilities, and handlers
- HTTP and STDIO transports, plus a
McpTransportInterfacefor custom protocols — see Custom Transports - Pluggable error handling and observability — swap in your own logging or monitoring via
McpErrorHandlerInterfaceandMcpObservabilityHandlerInterface— see Error Handling and Observability - Granular permissions — per-server transport authentication and per-ability permission checks — see Transport Permissions
Architecture
See the Architecture Overview for the full component breakdown.
Getting Started
Follow the Quick Start Guide to register your first ability and expose it via MCP, or jump straight to the Basic Examples for complete tool, resource, and prompt samples.
WordPress abilities are private by default. Set meta.public (or meta.mcp.public) to true to expose one, then reach it through the default server's three meta-tools (mcp-adapter/discover-abilities, mcp-adapter/get-ability-info, mcp-adapter/execute-ability) — see Creating Abilities for the full opt-in model.
Connecting MCP Clients
Connect via WP-CLI over STDIO, or point an HTTP client at /wp-json/mcp/mcp-adapter-default-server. Configuration examples for Claude Desktop and other MCP clients — both direct STDIO and HTTP-via-proxy — are in the CLI Usage Guide.
