ChatGPT

import { Aside } from ‘@astrojs/starlight/components’;

ChatGPT connects via **Actions** (OpenAPI schema), not MCP. The endpoint is the REST API, not `/mcp`.

Setup

1. Go to chat.openai.com/gpts → Create a GPT
2. In the Configure tab, click Add actions
3. Import the OpenAPI schema:

https://YOUR-SITE.com/wp-json/mcpwp/v1/openapi.json

4. Set authentication:

   • Type: API Key
   • Auth type: Custom header
   • Header name: X-API-Key
   • Value: mcpwp_YOUR_KEY

5. Save and test

Limitations vs MCP

ChatGPT Actions have a tool count limit (~30). When connecting via Actions, only the most common tools are exposed. For full access to all tools, use Claude Desktop or Cursor via MCP.
