All three plugins in this course do the same basic job, they turn your WordPress site into something an MCP client can talk to. The differences are in setup style, hosting, and how they handle authentication.
R
Runs entirely inside your own WordPress install. No outbound calls to Royal Plugins' own servers, API key or OAuth 2.1 auth, and 40+ tools covering posts, pages, WooCommerce, media, users, and menus.
m
Every AI client is registered as its own identity, with a role-based ability list you set per connection. Good fit if you need fine-grained, per-role permission control.
W
Routes through a hosted gateway (mcp.wpvibe.ai) with credentials encrypted using AES-256-GCM, and adds WP-CLI command access and safe theme file editing on top of the usual content tools.
If you are not sure, start with Royal MCP for a fully self-hosted setup, or WPVibe if you want the fastest one-click authorization flow. The next modules cover installing and connecting each one, in order.
