What is the JetEngine MCP server?
The JetEngine MCP server from AcrossAI lets Claude, ChatGPT, Cursor and any other MCP client list, read and update JetEngine options pages on your WordPress site. It runs inside WordPress through the free Abilities Manager and MCP Manager plugins, and works through JetEngine itself — with no third-party relay in between.

What your AI can do with JetEngine
JetEngine options pages hold the site-wide values your templates and listings read everywhere. These abilities let an AI assistant find every options page, read what is stored on it, and change a single field — without clicking through the JetEngine dashboard.
Find every options page
List each options page with its slug, name, storage key and fields.
Read stored values
See exactly what an options page holds right now, straight from wp_options.
Change one field
Update a single value and leave every other field on the page untouched.
Any value shape
Write text, numbers, toggles, arrays and objects, such as repeater rows.
Troubleshooting
JetEngine value not changing? Three reasons it happens quietly.
Each of these leaves the options page looking saved while the site keeps showing the old value.
The field name doesn’t match
Field names are case-sensitive. Get a JetEngine Options Page shows the exact names before you write.
The value has the wrong shape
A repeater expects an array, not text. Pass the shape the field stores.
The page is still cached
Templates read the new value at once, but cached pages don’t. Purge the page cache after the change.
Try asking
Paste one into Claude, ChatGPT or Cursor once your site is connected.
“Which JetEngine options pages does this site have?”
“What’s saved on the Contact Details options page?”
“Change the support phone number to +91 22 4000 1234.”
“Turn off the promo banner toggle on the Site Settings page.”
“Update the opening hours on the Store Info page.”
“Show me every field on the Footer options page.”
