Frequently Asked Questions

Common questions about Flex MCP – Connect ChatGPT, Claude and AI agents with MCP, Undo, Abilities and Tools.

Yes. For images, use wp_upload_image with a conversation file instead of slow base64 transfer. Its existing image_data + filename input remains available for older clients. For documents or image optimization, enable wp_upload_media in MCP Server > WordPress Tools. Refresh your client's tools after updating. Documents must be allowed by WordPress; executable files, HTML, XML and SVG are blocked. Conversation file downloads are limited to 20 MiB or the lower site limit. With wp_upload_media, request JPEG/WebP conversion, maximum dimensions and a target size, for example JPEG at 1600 pixels wide and no more than 400 KiB. Processing may reduce quality and dimensions; if the target cannot be met, the tool returns an error without leaving a successful oversized upload. Legacy base64 image uploads remain compatible.

The AI Copilot is a floating assistant that appears inside the WordPress editor (Gutenberg or Classic). It reads the context of what you’re editing and helps you write, rewrite, optimize, generate tags, create excerpts, and even generate images — all without leaving the editor. Every change can be undone with one click.

The Copilot lives inside the post/page editor and is focused on writing and content editing. It works directly with the editor fields (title, content blocks, excerpt, tags, etc.). The Chat Agent is a standalone admin page where you can manage your entire WordPress site through conversation — create posts, manage WooCommerce orders, check settings, install plugins, and more. Both use the same AI provider and API key.

Go to Flex MCP → AI Chat Agent → Settings Choose your AI provider (OpenAI, Claude, Gemini, or installed WordPress AI Client connectors like OpenRouter/Mistral) Enter your API key (you get this from your AI provider's website) Go to the Chat tab and start talking!

OpenAI, Claude, and Gemini all work great, and you can also use OpenRouter or Mistral via WordPress AI Client connectors. Here's a quick comparison: OpenAI (GPT-4o / GPT-4.5) — Best overall balance of speed and quality Claude (Opus / Sonnet) — Excellent at understanding complex instructions and writing Gemini (2.5 Pro / Flash) — Great value, fast responses You can switch providers at any time from the Settings tab.

The agent has access to 122+ tools covering: Content — Create, edit, delete posts, pages, and comments Media — Upload, list, and manage images and files AI Generation — Generate images (DALL·E, Imagen) and videos (Sora, Veo) with AI WooCommerce — Products, orders, coupons, customers, shipping, taxes Taxonomies — Categories, tags, custom taxonomies Settings — Site options, menus, navigation System — Plugins, themes, site health You control which tools are available through Profiles.

Yes, with multiple layers of protection: OAuth 2.1 with PKCE — Industry-standard secure authentication for external AI clients, no shared passwords Tool confirmations — In "Ask User" mode, you approve every action before it executes Permission checks — Every tool verifies WordPress capabilities before running Profiles — Restrict which tools are available (e.g., "Read Only" profiles) Token management — Revoke access for any client instantly from the admin panel

Model Context Protocol (MCP) is a standard for connecting AI agents to data sources and tools. This plugin implements an MCP server so external AI clients like ChatGPT or Claude Desktop can discover and use your WordPress tools. This is in addition to the built-in AI Chat Agent.

Yes! The plugin includes 61 WooCommerce tools. They activate automatically when WooCommerce is installed. Ask your AI agent "Show me today's orders" and it just works.

Yes, through WordPress Abilities. Legacy Custom Tools have been retired for security reasons; use plugins that register WordPress Abilities with explicit schemas and permission callbacks, then import them from the Abilities tab.
