FAQ
What is MCP?
Model Context Protocol (MCP) is a standard protocol for exposing tools and data to AI agents. This plugin implements an MCP-compatible server for WordPress.
How do I connect ChatGPT?
- Create an Application Password in your WordPress profile (Users Profile)
- Create a custom connector in ChatGPT
- Use the SSE endpoint URL with HTTP Basic Authentication
- ChatGPT will discover all available tools automatically
Is this safe for production sites?
Yes, when configured properly:
* Uses WordPress Application Passwords (native security feature)
* Each Application Password is tied to a WordPress user with specific permissions
* Use profile-based restrictions (e.g., “WordPress Read Only”)
* Review enabled tools in the Tools Management tab
* You can revoke Application Passwords at any timeWhat permissions do AI agents have?
Permissions are determined by:
1. The WordPress user’s Application Password used for authentication
2. The active profile (which tools are enabled)
3. Individual tool capability requirementsCan I customize which tools are available?
Yes! You can:
* Apply predefined profiles
* Manually enable/disable individual tools
* Create custom profiles
* Export/import profile configurationsDoes this work with WooCommerce?
Yes! The plugin includes 61 WooCommerce-specific tools. WooCommerce tools will only function when WooCommerce is installed and active.
How do I troubleshoot connection issues?
- Check the Settings tab for test commands
- Test with PowerShell scripts (included in examples/)
- Verify your hosting doesn’t block SSE connections
- Check WAF/CDN settings (may block long-lived connections)
- Review debug.log with WP_DEBUG enabled
Can I use this without WooCommerce?
Absolutely! The 55 WordPress tools work independently. WooCommerce tools are optional.
What are Custom Tools?
Custom Tools is a powerful feature that lets you create your own AI tools using PHP code. This means you can expose ANY plugin’s functionality to AI agents – from querying Contact Form 7 submissions to controlling cache plugins. Each Custom Tool has a name, description, optional input schema, and PHP code that executes when called.
How do I create a Custom Tool?
- Go to StifLi Flex MCP Custom Tools
- Click “Add New Tool”
- Enter a name (e.g., “custom_my_feature”)
- Write a description that helps AI understand when to use the tool
- Add your PHP code (the code receives
$argswith any input parameters) - Optionally define an input schema for structured parameters
- Save and enable the tool
The plugin includes several examples to get you started!
