What is the WPCode MCP server?
The WPCode MCP server from AcrossAI lets Claude, ChatGPT, Cursor and any other MCP client create, place and debug code snippets, with every new snippet landing inactive on your WordPress site. It runs inside WordPress through the free Abilities Manager and MCP Manager plugins, and works through WPCode itself — with no third-party relay in between.

What your AI can do with WPCode
WPCode is where most WordPress sites keep their custom PHP, JavaScript and CSS. These abilities let an AI assistant write and place snippets through WPCode’s own save routine, find the one that is breaking the site, and install from the WPCode library — with every new or installed snippet landing inactive until you switch it on.
Write snippets safely
Create PHP, JS, CSS and HTML snippets through WPCode’s own save routine. New snippets always start inactive.
Place them precisely
Choose the auto-insert location and conditional logic. Unknown locations and Pro-only rules are refused by name.
Find the broken snippet
See which snippets have recorded errors, whether safe mode is on, and what the loader cache is actually running.
Use the WPCode library
Search, install and update library snippets and packs. Everything installed lands inactive.
Troubleshooting
Code snippet not working? Three reasons it happens quietly.
Each of these leaves the snippet looking active in the list while nothing changes on the site.
It failed its activation test
WPCode test-runs PHP on activation and quietly leaves a failing snippet off. activate-snippet reads the state back and says so.
The loader cache disagrees
WPCode runs what its cache holds, not what the list shows. list-snippets reports what the cache contains.
A Pro-only rule never matches
The free edition stores Pro conditional rules and then never matches them. set-conditional-logic refuses them by name.
Try asking
Paste one into Claude, ChatGPT or Cursor once your site is connected.
“Add a snippet that disables comments on all pages, but leave it inactive.”
“Which snippet is causing the white screen on the checkout page?”
“Show me every snippet with a recorded error.”
“Move the Google Analytics snippet to the footer.”
“Find a library snippet that disables the admin bar for subscribers.”
“Which library snippets on this site have updates available?”

WPCode + AI questions
Is there an MCP server for WPCode?
Yes. AcrossAI turns your WordPress site into an MCP server with dedicated WPCode abilities, so Claude, ChatGPT, Cursor or a local model can work with WPCode directly. It’s free on WordPress.org.
Can ChatGPT or Claude manage WPCode?
Yes, once your site is connected over MCP. Ask in plain English and your AI calls the WPCode abilities on this page, with risky changes gated behind an explicit confirm.
Is the WPCode integration free?
Yes. All of its abilities ship in Abilities Manager, which is free on WordPress.org.
Can the AI run code on my site without me knowing?
No. Created and installed snippets always land inactive, and activating, changing or deleting code needs an explicit confirm.
Does it work with WPCode Lite?
Yes. The abilities work with the free edition, and Pro-only features such as advanced conditional rules are refused by name rather than stored silently.
Which AI assistants work with it?
Any MCP client: Claude, ChatGPT, Gemini, Grok, Cursor, Claude Code, and local runtimes such as Ollama, LM Studio and Open WebUI.
Does my site data pass through AcrossAI’s servers?
No. Your WordPress site runs the MCP server and your AI client connects to it directly. There is no hosted gateway in the middle.
Is AcrossAI affiliated with WPCode?
No. AcrossAI built and maintains this integration independently, using WPCode’s public APIs.
