Oxygen
Oxygen is a visual website builder plugin for WordPress with a built-in MCP server (Agent Connector) that connects your existing AI agents to build sites conversationally, while also letting you build pages by hand in the visual editor.
About Oxygen
Oxygen is a visual website builder plugin for WordPress. After installation, you can build pages by hand in the visual editor, or use the built-in Agent Connector (an MCP server with Abilities API support) to connect your existing AI agents (such as Claude, Codex, Gemini, Cursor, or other MCP clients) to WordPress and build sites by describing them in conversation. It supports dynamic data fields and offers integrations with custom field plugins like ACF, Meta Box, and Toolset. The license is a one-time purchase that can be used on an unlimited number of sites and includes lifetime updates and lifetime support. Note that users with access to Oxygen can execute arbitrary PHP code via the Code Block element, and the official documentation warns against granting Oxygen access to untrusted users. Some advanced settings (such as applying the the_content filter to content designed in Oxygen, or allowing unfiltered HTML in dynamic data output) are disabled by default, and the official documentation advises understanding the potential security implications before enabling them.
