Page Builder Sandwich: connect an AI agent (MCP)

Page Builder Sandwich makes your WordPress site an MCP server: an AI app such as Claude, Cursor or VS Code can read and change Page Builder Sandwich's content and settings through it, signed in as you.

Claude and ChatGPT: sign in (no password to copy)

Add https://your-site/wp-json/pbs/v1/mcp as a custom connector in Claude (Settings → Connectors), or as an app in ChatGPT developer mode. The app opens your site; sign in to wp-admin and press Allow. It can then do only what your WordPress account may do, and you can disconnect it in Page Builder Sandwich's AI agents (MCP) settings. Your site needs pretty permalinks.

Other apps: before you start

1. WordPress 6.9 or newer. In Page Builder Sandwich's settings, Allow AI agents (MCP) is on by default.
2. In wp-admin open Users → Profile → Application Passwords, add one named after your AI

app, and copy it (it is shown once). Your connection address is https://your-site/wp-json/pbs/v1/mcp.

Claude Desktop and Cursor

Settings → Developer → Edit Config (Claude Desktop) or .cursor/mcp.json (Cursor):

{"mcpServers": {"page-builder-sandwich": {"command": "npx", "args": ["-y", "@automattic/mcp-wordpress-remote@latest"], "env": {"WP_API_URL": "https://your-site/wp-json/pbs/v1/mcp", "WP_API_USERNAME": "your-username", "WP_API_PASSWORD": "your-application-password"}}}}

VS Code

.vscode/mcp.json uses servers instead of mcpServers, with "type": "stdio" added.

Claude Code

claude mcp add page-builder-sandwich -e WP_API_URL=https://your-site/wp-json/pbs/v1/mcp -e WP_API_USERNAME=your-username -e WP_API_PASSWORD=your-application-password -- npx -y @automattic/mcp-wordpress-remote@latest

Other apps

Any app that runs MCP servers can use the same command; one that connects to remote servers with a header can call the address directly with your username and application password. On the server itself: wp mcp-adapter serve --server=page-builder-sandwich --user=<login>.

Safety

Every ability checks the WordPress permission it names for the exact page or post, so an agent can never do more than the user it signs in as; visitors and subscribers are always refused. Disconnect the app (or revoke its application password), or switch Allow AI agents (MCP) off, to stop it at once.
