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

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.

MVP Docs adds a simple documentation system to your WordPress site. It creates a Docs custom post type with categories, a clean archive page, and a markdown import tool — nothing more. Why MVP Docs? AI tools like Claude and ChatGPT are excellent at generating documentation in Markdown format. MVP Docs was built to take advantage of that — paste your AI-generated .md files straight into WordPress with a single click. No copy-pasting HTML, no reformatting, no fussing with blocks. Just import and publish. Beyond the AI workflow, most documentation plugins are overbuilt. They add custom page builders, proprietary editors, dozens of database tables, and megabytes of JavaScript. MVP Docs takes the opposite approach: Uses the native WordPress block editor Works with any theme (block themes and classic themes) Stores content as standard WordPress posts Loads zero scripts or styles outside of doc pages No lock-in — your content is just posts and taxonomies No external dependencies — everything ships with the plugin Features Docs post type with archive at /docs/ Doc Categories for organizing content Search — AJAX-powered typeahead dropdown on the archive and category pages, with a dedicated search results page at /docs/search/ Markdown import — upload a .md file and it converts to native Gutenberg blocks (tables, code blocks, lists, and all GFM features) Import / Export — export docs, categories, and settings as a JSON file, or include referenced images in a zip bundle; import on another site Archive page — docs grouped by category in a card grid Category archives — full list of docs in a category with search bar Search results page — dedicated page with breadcrumbs and themed card layout Breadcrumbs on single doc pages Settings — archive layout (columns, border radius, docs per category), colors, page titles, sort order, custom slugs, category ordering via drag-and-drop Block theme support — registers proper block templates for single docs, archives, category pages, and search Classic theme support — falls back to PHP templates with get_header()/get_footer() WP-CLI — full command-line coverage so an AI agent or shell script can configure and populate a docs site without ever opening wp-admin Markdown Import — Built for AI-Generated Docs AI tools produce clean, well-structured Markdown. MVP Docs lets you import those .md files directly into the block editor with one click. The sidebar includes an “Import from Markdown” button — upload a file and it gets parsed client-side with full GitHub Flavored Markdown support (via marked.js), then converted into native Gutenberg blocks. The first # Heading becomes the post title automatically. Use your favorite AI to generate docs, how-to guides, or knowledge base articles in Markdown, then import them into WordPress without any reformatting. Supported: headings, bold, italic, links, images, tables, fenced code blocks with syntax hints, task lists, strikethrough, blockquotes, horizontal rules, ordered and unordered lists. Import / Export Go to Docs > Settings > Import / Export to: Export docs, categories, and/or settings as a single JSON file Import a previously exported file to restore or migrate content between sites Existing docs with the same title are skipped during import to avoid duplicates. Categories are created automatically if they don’t exist. WP-CLI Every admin action has a command-line equivalent, so a docs site can be stood up and populated entirely from a shell script or AI agent. Run wp mvp-docs --help for full details on any command below. Content wp mvp-docs import-md Import a Markdown file as a doc. Output is byte-identical to the sidebar Markdown importer — same blocks, same title extraction from the first # heading. wp mvp-docs import-raw Import a raw HTML file as a doc. Block-commented HTML is preserved as-is; plain HTML renders as a Classic block in the editor. Both import commands accept: * --title= — override the extracted title * --slug= — explicit post slug * --excerpt= — short description shown on category/search pages * --category= — assign to this category (created if missing) * --sort-order= — in-category sort priority (lower appears first) * --status= — post status (default: publish) * --dry-run — print the generated markup instead of creating a post Backup and migration wp mvp-docs export [--docs] [--settings] [--with-images] [--output= ] [--pretty] Dump docs, categories, settings, and category order to a single JSON bundle. Omitting --docs and --settings exports everything. Pipe to stdout or write to a file. Pass --with-images to bundle referenced images into a zip alongside export.json (requires --output). wp mvp-docs import Restore a previously exported file. Auto-detects .json and .zip bundles; for zips, referenced images are sideloaded into the media library and content URLs are rewritten. Docs are deduplicated by title, so running the same import twice is safe. Structure wp mvp-docs reorder-categories ... Set the display order of categories. Accepts term IDs or slugs. Settings wp mvp-docs settings list [--format=table|json|yaml|csv] Show every setting with its current value, description, and allowed form — self-documenting so you never have to read the source to discover what’s configurable. wp mvp-docs settings get Print a single setting’s value. wp mvp-docs settings set ... Update one or more settings. Values run through the same sanitizer as the admin UI; if a value is rejected (e.g. columns=7 when the allowed range is 1–4), a warning names the allowed form and shows the actual saved value. Changing docs_slug or category_slug auto-flushes rewrite rules.
