Starting price / year
Site-count comparison note: Royal MCP Pro at $79/yr covers 1 site (Personal Founder). WPVibe Pro at $99/yr covers unlimited sites at a metered daily tool call cap on the account. If you manage many sites but call each one lightly, WPVibe's account-wide cap is designed for that shape. If you work deep on fewer sites, Royal MCP Pro's per-site licensing removes the daily-cap ceiling entirely. See the Usage Caps table below for the exact Pro-tier number.
HONEST FIT-MAP
When to Pick Which
Both plugins ship real capability. They're built for different agency shapes. Here's how to know which one is yours.
Pick WPVibe if...
You spread light activity across many sites
- You manage 20-60 client sites but only touch each one occasionally
- Your typical monthly call volume per site fits comfortably under a shared daily cap
- You prefer a hosted service — someone else's uptime, someone else's OAuth infrastructure
- You're OK with client-site content flowing through a third-party relay endpoint on every tool call
- You're already in the Awesome Motive ecosystem and want another tool from that vendor
- You want metered pricing that fits light-touch, occasional-use workflows
Pick Royal MCP Pro if...
You work deep on portfolio sites
- You run bulk migrations, active builds, or cross-plugin composers on a smaller set of client sites
- You need unlimited daily tool calls per site — no ceiling on how much AI-driven work you push through
- Client data can't route through a third-party relay for compliance, contract, or trust reasons
- You need first-class Divi 4+5 depth (15 Divi tools total: 9 Free-tier + 6 Pro-tier including the shortcode-to-blocks migrator) or Elementor Pro depth (10 tools)
- You need WooCommerce Pro bulk ops with two-step commit + 72-168h undo on every batch
- You run FormForge Pro or Royal Affiliate Pro and want AI-scriptable coverage on those (14 dedicated tools with 72-168h undo on every destructive write)
- Universal audit log on every write is required for client work
