TL;DR

AI summary of the plugin's readme

AI Engine is for WordPress site owners and developers who want to add AI capabilities like chatbots, content generation, and automation to their site. It connects WordPress to AI providers (OpenAI, Anthropic, Google, Mistral, and others) and exposes those capabilities through chatbots, AI forms, function calling, and an MCP server so AI agents can interact with the site.

Customizable chatbots with themes
Realtime audio conversations
Copilot editor assistant for text
AI Forms with conditional logic
Embeddings and knowledge bases from PDFs
Vector database integration (Pinecone, Chroma, Qdrant)
Function calling to WooCommerce and APIs
MCP server for AI agents

Frequently Asked Questions

Common questions about AI Engine – MCP Server & AI Chatbot for WordPress, with Claude, ChatGPT & Gemini

This error comes from OpenAI's API, not AI Engine. Set up billing limits in your OpenAI account. Caching plugins can sometimes store error responses, so clear your caches too.

AI Engine can be used by site owners, administrators, and visitors via chat widgets. To set query limits and prevent unlimited model runs, follow the Managing Limits guide.

AI models support many languages, but quality varies. There's no definitive list since models are constantly updated. Test your language in the AI Playground.

MCP (Model Context Protocol) exposes WordPress tools to AI agents. Learn how to enable the MCP endpoint, choose which tools to expose, and secure them. You can manage posts, comments, users, media, and more. Administrators get full access, and you can also let Editors connect with their own account for content only.

Yes. The MCP server is part of this free plugin, with no account and no daily cap. There is no extra server to host: Claude and ChatGPT connect to your WordPress site with OAuth and use the plan you already have, so no API key is needed. The facts, side by side with another MCP plugin.

Yes, but you don't need it. AI Engine already does everything WordPress AI offers, and more: it connects to every major provider, and adds chatbots, AI Forms, embeddings, a dedicated MCP server with more than 130 tools, and usage insights. That's why we don't recommend installing the WordPress AI plugin alongside it. If you already use it, that's fine: we make sure both play nicely together. On the Connectors page, choose to let AI Engine manage your providers: the API keys you already saved there are reused, both screens stay in sync, and the AI features of WordPress run through AI Engine, so their usage shows up in its Insights.

No. AI Engine has its own MCP server, with more than 130 tools (over 200 with SEO Engine, Code Engine and Social Engine), OAuth for Claude and ChatGPT, and per-user access, so there is nothing else to install. The MCP Adapter is the official WordPress bridge that turns the abilities other plugins register into MCP tools. Think of it as a power socket, and AI Engine as the appliance. If you already run it, both live side by side on different endpoints, and the Abilities option in the MCP tab lets AI Engine's own server expose those abilities too.

You can't completely block the model's built-in knowledge, but you can use smart prompts and embeddings to steer conversations toward your content.
