AcrossAI MCP Manager vs Flex MCP – Connect ChatGPT, Claude and AI agents with MCP, Undo, Abilities and Tools.

Connect ChatGPT to WordPress. Connect Claude to WordPress. Connect Grok to WordPress. Connect any MCP-compatible AI assistant to WordPress.

External Services This plugin connects to third-party AI services to power the AI Chat Agent, AI Copilot, image generation, and video generation features. No data is transmitted until you explicitly configure an API key and initiate a request. What data is sent: Your WordPress content (post text, metadata, product details) as included in AI prompts, and MCP tool execution results when using the MCP server with external AI clients. When data is sent: Only when you have configured an API key for a provider AND actively send a message to the AI agent or Copilot, or when an external MCP client makes an authenticated request to the MCP server endpoint. Supported services and their policies: OpenAI — Used for GPT models (AI Chat Agent, AI Copilot), GPT Image / DALL·E (image generation), and Sora (video generation) Terms of Use | Privacy Policy Anthropic Claude — Used for Claude AI models (AI Chat Agent, AI Copilot) Terms of Service | Privacy Policy Google Gemini — Used for Gemini AI models (AI Chat Agent, AI Copilot), Gemini Image + Imagen 4 (image generation), and Veo 2/3 (video generation) Terms of Service | Privacy Policy Google Search Console – Used only when you connect your Google account in the SEO settings, for read-only site/search performance data. Terms of Service | Privacy Policy When using the MCP server with external AI clients (ChatGPT, Claude Desktop, LibreChat, etc.), API requests are made by the AI client’s backend servers to your WordPress MCP endpoint. The plugin itself does not send data to third parties in this scenario — the external MCP client initiates all communication.
