MCP in WordPress: Why Your Site Is Learning to Talk to AI Agents

WordPress now has official MCP support. MCP, the Model Context Protocol, is the interface that assistants like Claude, ChatGPT and Cursor use to call external tools.

It works through two pieces. Plugins and themes register individual actions through the Abilities API, and the MCP Adapter, which lives in the official WordPress GitHub organization, exposes those actions as tools an agent can call. WordPress 6.9 or newer is required.

If you try it, do it on staging first, and authenticate the connection as a limited user with an application password you can revoke. The agent gets exactly the permissions that account has, and nothing about MCP changes that.
