Getting Started

Connect your first AI client to WordPress.

Use this guide to install StifLi Flex MCP, connect an MCP-compatible client and verify that tool discovery works before enabling write permissions.

Requirements Install the plugin Copy the SSE URL Connect ChatGPT or Claude Authorize with OAuth Test the connection

Requirements

WordPress 5.8 or newer.
PHP 7.4 or newer.
An administrator account for setup.
HTTPS for production OAuth connections.
An MCP-compatible client such as ChatGPT, Claude Desktop, LibreChat, Cursor, Cline or Roo Code.

Install the plugin

Install StifLi Flex MCP from WordPress.org or upload the plugin folder.
Activate it from the WordPress admin.
Open StifLi Flex MCP in the admin menu.
Start with a safe profile such as Safe Mode or WordPress Read Only.

Recommendation: verify a read-only connection before exposing write tools for posts, products, orders, settings or media.

Copy the SSE URL

Open StifLi Flex MCP > MCP Server > Settings. The connection panel displays the SSE URL used by external MCP clients.

The endpoint usually follows this pattern:

/wp-json/stifli-flex-mcp/v1/sse

Connect ChatGPT or Claude

Client	Setup path
Claude Desktop	Open Connectors, add a custom connector and paste the SSE URL.
ChatGPT	Use Apps & Connectors, enable developer mode and create an app using the SSE URL with OAuth.
LibreChat or other clients	Use the MCP/SSE connector settings provided by the client.

Authorize with OAuth

When the client connects, WordPress opens an authorization flow. Log in, review the client request and authorize. StifLi Flex MCP uses OAuth 2.1 with PKCE for modern clients.

Test the connection

Ask the AI client to run a basic connectivity test. The safest first tool is mcp_ping, which verifies routing and authentication without modifying the site.

Next step: after a successful test, move to the Tools Catalog and choose the smallest profile that fits your workflow.
