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 McpTransportInterface for custom protocols — see Custom Transports
- Pluggable error handling and observability — swap in your own logging or monitoring via McpErrorHandlerInterface and McpObservabilityHandlerInterface — see Error Handling and Observability
- Granular permissions — per-server transport authentication and per-ability permission checks — see Transport Permissions
Architecture
See the Archit
