Code Engine – PHP Snippets, AI Functions & Automation for WordPress vs VigIA – AI Visibility, Analytics & Control

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. Code Engine gives you a place to build capabilities that your AI, your workflows, and your external tools can all use. Native to WordPress Clean, fast, and built the WordPress way. No clunky external dashboards, no bloat. AI-native Write snippets with AI, expose them to AI. The whole loop lives in your wp-admin. Developer friendly REST API, MCP tools, function calling, scheduling, import/export, and plenty of filters to hook into. Cared for Part of the Meow Apps family, with regular updates and a real human behind it. 💕

No data is sent to external servers. Abilities API VigIA is one of the first WordPress plugins to implement the Abilities API introduced in WordPress 6.9. This API allows AI agents, automation tools, and external systems to discover and interact with VigIA’s functionality in a standardized, secure way. What are Abilities? Abilities are self-contained units of functionality that VigIA exposes through WordPress’s central registry. Each ability has defined inputs, outputs, and permissions, making it easy for automation tools to understand and use them. Available Abilities VigIA registers the following abilities: Analytics vigia/get-crawler-stats – Get statistics about AI crawler visits (total visits, unique crawlers, pages crawled) vigia/get-top-crawlers – Get a ranked list of most active AI crawlers vigia/get-top-pages – Get the most crawled pages on your site Blocking vigia/get-blocked-items – List all blocked crawlers and IP addresses vigia/block-crawler – Block a crawler by User-Agent pattern vigia/unblock-crawler – Remove an existing block Robots.txt vigia/get-robots-rules – Get current AI crawler rules in robots.txt vigia/add-robots-disallow – Add a Disallow directive for a crawler vigia/remove-robots-rule – Remove a robots.txt rule Use Cases Automated monitoring: AI agents can query crawler statistics and alert you to anomalies Reactive blocking: Automation tools can block crawlers that repeatedly ignore robots.txt External dashboards: Aggregate data from multiple WordPress sites with VigIA installed WP-CLI integration: Future command-line access through the Abilities API n8n / Make workflows: Build custom automation flows using VigIA’s abilities Requirements The Abilities API ships with WordPress 6.9 and later. On older WordPress versions, VigIA works normally but abilities and MCP are not available. MCP Server (Model Context Protocol) VigIA exposes its 9 abilities as native MCP tools to any MCP-compatible client (Claude Code, Cursor, Claude Desktop, Codex CLI, Antigravity, Continue, Cline, Zed and similar) using the official WordPress MCP Adapter. The adapter ships bundled with the plugin, so the MCP endpoint is active right after installation — no Composer step or terminal access required. Requirements WordPress 6.9 or later (provides the Abilities API) Quick connect (recommended) Open VigIA > Extras > MCP and click “Generate password and connection commands”. The plugin creates a dedicated Application Password named VigIA MCP and renders ready-to-paste commands for Claude Code, Cursor, Claude Desktop and a generic block (URL + Authorization header) for any other MCP client. The plain password is shown only once. If you lose it, revoke the entry from the same panel and generate a new one. Endpoint https://your-site.example/wp-json/vigia/v1/mcp The endpoint uses HTTP Basic auth with the WordPress Application Password. The user must have the manage_options capability. Connecting Claude Code Quick Connect builds the full command for you. The shape is: claude mcp add --transport http vigia https://your-site.example/wp-json/vigia/v1/mcp --header "Authorization: Basic BASE64_OF_USER_AND_APP_PASSWORD" Claude Code merges the new entry into its config file automatically — no risk of breaking other servers. Connecting Cursor Save the JSON block from Quick Connect as ~/.cursor/mcp.json. You can also reach this file from inside Cursor at Settings → Cursor Settings → MCP. If the file already exists with other content, see the FAQ. Claude Desktop and other clients Claude Desktop does not speak HTTP MCP, so it needs a small bridge and a config file of its own. Any other client (Codex CLI, Continue, Cline, Antigravity, Zed, or your own) takes the two raw values Quick Connect exposes: the server URL and the Authorization header. Both cases are covered in the FAQ, together with how to merge VigIA into a config file that already exists without losing what is in it. Read-only mode If you only want your AI to consult VigIA (not change anything), enable “Read-only mode” in the MCP tab. While on, write actions (block, unblock, robots changes) return a permission denied error. Read actions (statistics, top crawlers, blocked items, robots rules) keep working. The toggle stores a vigia_mcp_read_only option that hooks into the vigia_can_write_via_abilities filter. Developers can still force read-only from a mu-plugin: add_filter( 'vigia_can_write_via_abilities', '__return_false' ); The mu-plugin filter at the default priority takes precedence over the toggle. Who can reach the endpoint The endpoint requires the capability to manage options, the same one every tool behind it already asked for. The vigia_mcp_transport_capability filter can lower that bar; each tool keeps its own permission check. After connecting Restart your MCP client after adding the server so it picks up the new tools. Then try a few prompts to confirm everything is wired up: “Show me VigIA crawler stats for the last 7 days.” “List the top 5 most crawled pages on this site.” “Add a robots.txt Disallow rule for TestBot and then list the current AI crawler rules.” The third example exercises a read + write + read round-trip, which is the most complete sanity check.
