MCP Server for WordPress – Connect Claude, ChatGPT & Gemini | AtlasAI Connector vs Code Engine – PHP Snippets, AI Functions & Automation for WordPress

AtlasAI Connector is the only WordPress MCP server with no limit on how many AI abilities your site can expose. It turns your site into a Model Context Protocol (MCP) server so AI assistants and autonomous AI agents like Claude, ChatGPT, Gemini, Cursor, and Claude Desktop can read, write, and manage your posts, pages, media, users, settings, and WooCommerce store through natural language. Your tool list is not a fixed catalogue. On top of the built-in abilities, the free plugin picks up every ability any plugin registers through the WordPress Abilities API, and turns WooCommerce’s own REST API into read-only AI tools. There is no cap on the number in either the free or the Pro version. Generate excerpts, feature images, summaries, titles, and alt text without leaving the post — on a secure MCP server built around OAuth 2.1 with PKCE, per-role access control, and an audit trail of every AI action, so each connection only does what you allow and nothing happens on your site unseen. How do I connect Claude, ChatGPT or Gemini to WordPress? Activate the plugin and your MCP server endpoint goes live at /wp-json/awfah_mcp/mcp. Enable one-click OAuth 2.1 under MCP Auth, paste that URL into Claude.ai, Claude Desktop, ChatGPT, Cursor, Windsurf, Claude Code, or Gemini CLI as a custom connector, and approve the consent screen in your browser — no manual tokens to copy. Headless and CI clients can fall back to JWT or Application Password auth. Step-by-step guides for each client are below under “Connecting AI Agents”. Does it work with my other plugins? Yes. Most MCP plugins only expose what they wrote themselves; AtlasAI Connector turns the plugins you already run into AI tools, two ways: Abilities API — free, unlimited. Any plugin that registers abilities through the WordPress Abilities API is picked up automatically. Nothing to configure, no per-plugin integration, and no cap on how many. REST API to AI tools — WooCommerce free, every plugin in Pro. Most plugins do not register abilities yet, but almost all of them register REST endpoints. AtlasAI Connector reads those endpoint definitions — their parameters, types and descriptions — and turns them into AI tools. The free version does this for WooCommerce. Pro does it for every plugin on your site. Each endpoint is graded on how well it describes itself, so you can see at a glance which tools an AI will use correctly and which need a better description first. Does it work with WooCommerce? Yes. The free version connects WooCommerce to your AI assistant in read-only mode: products, store data, orders and customers. An AI can answer “how many orders came in yesterday”, “which products are low on stock”, or “what did this customer buy” — and cannot change anything in your store. Pro adds everything that writes — create and update products, fulfil orders, issue refunds, edit customers — plus the remaining WooCommerce endpoint groups: reports, coupons, settings, shipping, taxes, webhooks and more. Pro also turns every other plugin’s REST API into tools the same way. You choose which groups are switched on, and nothing is handed to an AI client until you grant it to a role. Do unlimited abilities slow down your site? No. Nothing in this plugin runs for visitors, so page load times are identical whether the feature is on or off. Measured on a real store with 396 WooCommerce endpoints switched on, registering hundreds of abilities takes under a millisecond and adds about 4 MB to peak memory — only on the two admin screens that list abilities, never on your dashboard or posts list. The real limit is not your server but how many tools a model can choose between well: most AI clients start picking the wrong tool past a hundred, so the plugin shows you the count, warns you when you pass it, and lets you narrow what each role can reach. Is an MCP server on WordPress secure? An MCP server hands an AI assistant real write access to your site, so this one is built to be governed, not trusted blindly: OAuth 2.1 with PKCE and dynamic client registration — your site is its own authorization server, with no client IDs, secrets, or long-lived tokens to leak. JWT and Application Password auth work as a fallback for headless and CI use. Every connection maps to a WordPress user — an AI client inherits that user’s role and can never exceed what the person behind it may do. Role-based access control — choose which modules and abilities each role may use. Pro adds per-ability RBAC, tool/resource/prompt access modes, and OAuth scope enforcement. Audit trail — with the official WordPress AI plugin’s request logging enabled, every ability and MCP tool call is recorded: the operation, the user, the duration, the outcome, and the AI provider used. Revoke access anytime — review and revoke connected clients under MCP Auth → Connected clients in one click. Your keys, your server — bring your own AI provider keys; nothing is proxied through us. Works with the official WordPress AI plugin AtlasAI Connector integrates with the official AI plugin instead of running a parallel system: our five AI experiments appear as feature cards on its Settings → AI screen, respect its per-feature toggles, and inherit its editorial Guidelines in every prompt so generated content stays on brand. You can hide the AI plugin’s duplicate experiments — per experiment or globally — so editors see one AI button, not two. Classic Editor supported All five AI experiments also work in the Classic Editor — unlike the official AI plugin, which is Block Editor only: Excerpt generation, title suggestions, and post summarization on the classic edit screen. AI feature image generation in the Featured Image box. Image alt text from the media modal — the AI is sent the actual image (vision), so it describes what is really in it. If your site still runs the Classic Editor — as millions do — you get the same AI tools without switching editors. Why choose AtlasAI Connector? Connect any AI client — Claude Desktop, Claude.ai, ChatGPT, Cursor, Windsurf, Gemini CLI, or any MCP-compatible tool over standard JSON-RPC 2.0. MCP server + AI content in one plugin — most WordPress MCP plugins do one or the other; AtlasAI Connector does both. Unlimited abilities — built-in tools for posts, pages, media, users and WooCommerce, plus every ability any other plugin registers through the WordPress Abilities API, discovered automatically. No numeric limit in free or Pro. Secure by design — OAuth 2.1 with PKCE and dynamic client registration, plus JWT and Application Password support, and per-role access control so each connection only sees what its WordPress user may use. Works on WordPress 6.8+ — bundles the Abilities API and MCP Adapter, so you need not wait for the core versions where these ship. Multi-provider AI — OpenAI, Google Gemini, or Anthropic Claude via the WordPress AI Client; provider keys set once are shared with core AI features. Workflow builder — combine abilities into reusable workflows from the dashboard or the post editor meta box. Modules — individually toggleable Each module can be enabled or disabled independently of the AtlasAI Connector dashboard: AI Content Steward (8 abilities) — AI content analysis, generation, and improvement. Posts Manager (13) — full CRUD for posts, categories, and tags. Pages Manager (5) — CRUD for WordPress pages. Media Manager (7) — upload, update, and manage media files. Users Manager (7) — search, create, and manage users. Custom Post Types Manager (6) — CRUD for any registered custom post type. REST API Tools (3) — discover and execute any WordPress REST endpoint dynamically. Site Info & Diagnostics (4) — site info, plugins, themes, and users at a glance. Settings Manager (3) — view and update WordPress settings. AI Store Manager — WooCommerce (26) — products, categories, tags, brands, orders, and sales reports. Requires WooCommerce. Error Debugger (4) — real-time PHP error monitoring with AI fix commands (details below). External Abilities (Pro) — automatically discovers every ability registered through the WordPress Abilities API by any plugin, however many there are, and exposes them through the same MCP server, workflows, and access control. WooCommerce AI Agent — 26 Store Abilities Turn Claude or ChatGPT into a WooCommerce AI agent: search and manage products, categories, tags, and brands, review orders, and pull sales reports by chatting with your AI assistant. All 26 store abilities run through the same MCP server, workflows, and role-based access control, and register only when WooCommerce is active. AI Content Generator: Write Blog Posts, Pages and Product Descriptions Six experiment panels run on your configured AI provider (OpenAI, Google Gemini, or Anthropic Claude), in both the Block Editor and the Classic Editor: Content Generation — an AI blog post generator and article writer built into WordPress. Give it a topic, pick an AI-generated title, edit the outline, then generate the full post and preview it before a single block reaches your editor. Works for blog posts, landing pages, any custom post type, and WooCommerce product descriptions. Excerpt Generation — one-click, SEO-friendly excerpts with tone/style presets. Title Suggestions — multiple SEO-friendly title ideas to pick from. Summarization — concise, neutral post summaries. Feature Image Generation — AI feature images generated from your post content. Alt Text Generation — vision-based alt text: the AI is sent the actual image, not just the filename, so descriptions reflect what is really in the picture. Every panel ships with editable prompts and tone/style presets — free. Pro extends every experiment with a prompt templates library, batch variants, generation history, model tuning, “Explain This Generation”, and keyboard shortcuts. Pro also lets Content Generation read your own site, so drafts link to posts and products that actually exist instead of invented URLs. Error Debugger Monitor PHP errors from plugins and themes in real time — no configuration required. Free: an error log grouped by file, email alerts with a copy-paste Fix Command for any AI assistant, and an admin dashboard widget. Pro: an MCP Fix Command you paste into Claude Desktop or Cursor so the AI reads the file, creates a backup, and applies the fix — plus Slack/Discord webhooks, a Backups Manager, and extended sources (Core, MU-Plugins, Drop-ins). WordPress Abilities API Support Every ability is registered through the standard WordPress Abilities API and exposed over MCP via the official MCP Adapter — both bundled as vendor dependencies, so everything works on WordPress 6.8+ today, before these APIs ship in core. With Pro, abilities that other plugins register via the Abilities API are auto-discovered and become MCP tools too. Works with the WordPress AI ecosystem AtlasAI Connector is built on the same AI Building Blocks as WordPress core — the AI Client and the Abilities API. Add your provider key once under Settings → Connectors, using the official AI Provider for OpenAI, AI Provider for Google, or AI Provider for Anthropic plugins, and AtlasAI Connector reuses it for its MCP server and AI experiments — no duplicate setup. AtlasAI Connector Pro AtlasAI Connector Pro adds: Unlimited Workflows — free version allows 3. T/R/P Access Modes — per-ability Tool/Resource/Prompt toggles for fine-grained MCP control. Advanced AI Experiments — prompt templates library, batch variants, explain reasoning, generation history, keyboard shortcuts. Workflow Prompt Builders — 6 pre-built prompt workflows (SEO Audit, Content Brief, Site Overview, and more). External Abilities — auto-discover every ability any plugin registers via the Abilities API. Per-Ability RBAC — assign individual abilities (not just modules) to each WordPress role. Error Debugger Pro — MCP Fix Command with automatic backups, Slack/Discord webhooks, Backups Manager. Priority Support — plus a 7-day free trial, no credit card required. Connecting AI Agents Connect your AI client First, in WordPress admin go to AtlasAI Connector → MCP Auth, enable One-click OAuth 2.1 connect, and copy your server URL — it looks like https://your-site.com/wp-json/awfah_mcp/mcp. Then: Claude Desktop — Settings → Connectors → Add custom connector, paste the server URL. Your browser opens the OAuth consent screen automatically — click Allow and your abilities appear as tools. Claude.ai (web) — Settings → Connectors → Add custom connector, paste the server URL, and approve the consent screen that opens in your browser. ChatGPT — Settings → Apps & Connectors → enable Developer Mode → create a new connector with the server URL (requires a ChatGPT plan with connector support). The OAuth consent opens in your browser. Cursor — Settings → MCP → Add new MCP server and paste the server URL (or add it to .cursor/mcp.json as a "url" entry), then approve the OAuth prompt in your browser. Windsurf — Windsurf Settings → Cascade → MCP servers → add a server with the URL as serverUrl in mcp_config.json, refresh, and approve the browser consent. Gemini CLI — run gemini mcp add --transport http wordpress https://your-site.com/wp-json/awfah_mcp/mcp, then /mcp auth inside the CLI to complete the browser consent. In every case the OAuth browser consent happens automatically — no client IDs, secrets, or tokens to copy. If your client cannot complete OAuth (headless/CI use, plain-HTTP local sites, or a subdirectory WordPress install), use the fallback instead: a JWT token or WordPress Application Password sent as an Authorization: Bearer header — full steps under MCP Auth → Documentation → “MCP Client Setup Guide”. How the OAuth connection works (in brief) AtlasAI Connector is its own OAuth 2.1 authorization server — your WordPress site is the identity provider. A connecting client discovers the server from .well-known metadata (RFC 9728 / RFC 8414), registers itself via Dynamic Client Registration (RFC 7591), and completes a PKCE authorization-code exchange (RFC 7636) after you approve the consent screen in your browser. The access token maps to your WordPress user, so your role and the per-role Access Control govern exactly what the connection can do. By default only users who can edit posts may authorize a connection (change it with the awfah_oauth_authorize_min_capability filter). Role-based MCP access Different WordPress users see different abilities depending on their role. Configure it under the Access Control tab: pick a role, check the abilities (and workflows) it may use, and save — changes apply immediately to every MCP connection authenticated as that role. An Administrator connection can use every ability while an Editor connection is limited to content abilities only, and you can run both side by side in the same AI client using two accounts.

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. 💕
