Code Engine – PHP Snippets, AI Functions & Automation for WordPress vs Clevera

Clevera is an AI-powered product that turns screen recordings into narrated tutorial videos and step-by-step help articles. This plugin links your WordPress site to your Clevera workspace so you can build a public help experience on your site without copying embed codes by hand. Once connected, editors can browse Clevera projects from inside the WordPress editor and add the Clevera Help Center block (or Elementor widget) to a page, then pick which project to show. Visitors get that project’s categories, screencasts, embedded videos, and related article content. When you update content in Clevera, the on-site experience reflects those changes on the next load — no re-exporting or republishing in WordPress. What you can do Connect your WordPress site to a Clevera workspace in a few clicks Review a clear connection disclosure and explicitly confirm before any data is sent to Clevera Browse and select Clevera projects inside the block editor and Elementor (for users with content-editing access) Render a public help center for the project chosen on that page Show project categories, screencasts, embedded videos, and related article content Filter and search screencasts by project, category, or keyword where the UI exposes those controls Rotate or disconnect the API key from WordPress, or manage the connection from the Clevera side How the connection works The plugin uses a guided setup flow instead of pasting a raw API key. From Settings → Clevera AI you are sent to Clevera to sign in and select a workspace. Clevera issues a short-lived exchange token; the plugin exchanges it for a site API key bound to your site URL. The key can be rotated automatically on a schedule and you can also rotate or disconnect manually. Requirements A Clevera account — sign up at clevera.ai WordPress 5.8 or later (as required by the plugin) PHP 7.4 or later Elementor (optional; required only for the Clevera Help Center Elementor widget) External services This plugin relies on external Clevera services to connect your site and to load help-center content. By default, the plugin does not start the connection flow until an administrator explicitly confirms the disclosure on the settings screen. https://app.clevera.ai Used for: * The connection flow between WordPress and Clevera * Exchanging the temporary connection token for the site API key * Validating the connection * Loading project, category, screencast, and article data for connected sites * Rotating and disconnecting the site API key Data sent to app.clevera.ai may include: * Site URL * Site name * Return URL for the connection flow * Authorization state token * Site API key in authenticated server-to-server requests * Selected project and content request parameters needed to load help-center data This service is contacted: * When an administrator connects the plugin * When an editor loads Clevera project choices * When the public help center loads data for the selected project * During scheduled connection validation, key rotation, or disconnect operations Terms of service: * https://www.clevera.ai/terms https://share.clevera.ai Used for: * Rendering Clevera-hosted embedded videos inside the help center Data sent to share.clevera.ai depends on the embedded player URL and may include: * The embed identifier * An embed access token generated by Clevera * The selected content language * Standard browser request metadata This service is contacted: * When a visitor loads a help center page that displays a Clevera video embed Privacy Site owners should review their own privacy disclosures if they use the public help center, because visitor browsers may load embedded content and assets from the Clevera domains above. The plugin’s connection flow is opt-in. An administrator must explicitly confirm the connection disclosure before site URL, site name, return URL, and a signed state token are sent to Clevera. Privacy-related information for the Clevera service is described in the terms linked in External services.

Code Engine is a snippets manager that doesn’t stop at snippets. Yes, it runs your PHP and JavaScript exactly where and when you want: frontend, backend, on a schedule, or inside your content. But its real magic is what happens after you write a function: the same little piece of code instantly becomes a tool your AI chatbots can call, a step you can drag into a visual workflow, and an endpoint the outside world can trigger. One function, three superpowers. Most “code snippets” plugins stop at a textarea and a toggle. Code Engine treats your functions as first-class building blocks for the whole Meow Apps ecosystem, and for anything that can speak REST. Think out of the box, let your creativity flow, because the possibilities really are endless! ✨ For more, check the official website and come say hi on the Discord. Quick Intro Hello! ☀️ I built Code Engine because I was tired of pasting mystery snippets into functions.php and praying. I wanted a place where small bits of code are organized, safe, AI-assisted, and reusable everywhere. Here’s the idea. You write a function (or let the AI write it for you from a plain-English description). That function immediately shows up in three places: AI Engine: your chatbots and MCP clients (Claude, ChatGPT, Claude Code) can call it as a tool, with real arguments. Ask “how many orders shipped today?” and your chatbot runs your function to answer. Workflow Engine: your function appears in the step picker as its very own block. Drag it onto the canvas, wire it between an AI step and a Slack step, done. No glue code. REST / External tools: give it a secure endpoint and a token, then trigger it from Make.com, n8n, Zapier, a cron job, or a webhook. You never wrote an “integration.” You just wrote a function. Code Engine did the rest. 🤝 Core Modules 🧩 Snippets Manager Backend, Frontend, Persistent, Scheduled, Functions, and in-content (PHP/JS) snippets, all in one clean dashboard with tags, search, scope filters, and priorities. 🪄 AI-Assisted Coding Describe what you want in plain English and let AI Engine write the snippet: code, name, arguments, and scope included. Refine existing code or implement it straight from your comments. 🤖 Functions as AI Tools Every Function snippet becomes a function-calling tool and an MCP tool, so your AI Engine chatbots (and external AI agents) can actually do things on your site, not just talk. 🔀 Functions as Workflow Steps Workflow Engine surfaces each of your functions as its own draggable step. Your custom logic becomes a first-class citizen on the automation canvas. 🌐 External Access (REST) Expose any runnable snippet through a secured REST endpoint with a bearer token. Perfect for Make.com, n8n, webhooks, and scheduled external jobs. 🛡️ Safe Mode A snippet that throws a fatal error is automatically caught and disabled before it can take your site down. Code with confidence. ⏰ Scheduling Run a snippet daily at a chosen time via WP-Cron (reports, cleanups, syncs) without touching the server crontab. 🧱 Code Blocks & Shortcodes (Pro) Drop PHP or JS straight into a post or page with a Gutenberg block or the [code-engine] shortcode, with safety guards. 🧩 Snippets, the way they should be Code Engine organizes your code by scope, so each snippet runs exactly where it belongs: Persistent: runs everywhere (frontend and backend). Your everyday “add this to functions.php” code, but managed. Frontend: runs only on the public site. Backend: runs only in the admin. Function: a named, callable function with typed arguments and defaults. This is the reusable building block (see below). Scheduled: runs on a WP-Cron schedule, at the hour and minute you pick. Content (PHP / JS): runs inside a specific post or page, via a Gutenberg Code Block or the [code-engine] shortcode (Pro). Everything is searchable, taggable, sortable by priority, and importable/exportable. The CodeMirror editor gives you proper syntax highlighting and keyboard shortcuts (Cmd+S to save, Cmd+Enter to run). A nikic/php-parser pass validates your PHP before it ever runs. 🪄 Let AI write it for you Don’t feel like writing the boilerplate? Describe the snippet in plain language and Code Engine, powered by AI Engine, generates the whole thing: the code, a sensible name, a description, the right scope, and, for functions, the argument list with names, types, and defaults. Already have code? Ask the AI to modify it from a prompt, or write a few comments describing what you want and let it fill in the implementation. It’s pair programming, right inside your dashboard. ✨ The big idea: write once, use everywhere This is what makes Code Engine different. A Function snippet is not just code you call from other code. It’s a reusable capability that the rest of your stack can plug into. The moment you save it, the same function is available in three places at once: 1. As an AI tool, for chatbots and AI agents With AI Engine active, your functions are exposed through function calling and over MCP (Model Context Protocol). Your on-site chatbot can run them mid-conversation, and external AI agents (Claude, Claude Code, ChatGPT, OpenClaw) can call them too. Want a chatbot that checks stock, looks up a booking, or kicks off a process? Write the function; the chatbot gains the skill. 2. As a workflow step, for automation With Workflow Engine, every active function shows up in the Add-step picker as its own block, named after your snippet, with one input per argument. Drag it onto the canvas and wire it between other steps: an AI step that summarizes, your function that saves, a Social Engine step that posts. There’s also a generic “Execute snippet (by ID / by name)” step when you want to call one dynamically. You never write integration code; your function is the integration. 3. As a REST endpoint, for the outside world Give a snippet a custom endpoint name and a bearer token, and it’s instantly callable from anywhere: POST /wp-json/code-engine/v1/snippets-endpoint/your-endpoint Pass arguments as JSON in the body, secure it with a token, and trigger it from Make.com, n8n, Zapier, GitHub Actions, or a humble cron job. Automation without a middleware bill. 🛡️ Safe by default Running arbitrary code is powerful, so Code Engine takes safety seriously: Safe Mode catches fatal errors and auto-disables the offending snippet, so a typo never white-screens your site. REST whitelisting means global snippets only run on trusted REST routes by default, so you choose what to open up. Per-snippet tokens secure your external endpoints. Validation with a real PHP parser before code is saved. For developers who want fewer guardrails, there’s a “Bypass REST Security” option and filters (mwcode_rest_authorized, mwcode_rest_whitelist) to tailor exactly what’s allowed. Works beautifully with the Meow Apps family Code Engine is one engine in a connected set, each one useful alone, magical together: AI Engine: chatbots, content generation, and MCP. Turns your functions into AI tools. Workflow Engine: visual automation. Turns your functions into draggable steps. SEO Engine: smart, lightweight AI SEO. Social Engine: schedule and automate social posts. Why Code Engine? Reusable, not throwaway Other snippet plugins give you a place to paste code.
