ChatGPT Business — MCP connector

ChatGPT Business supports MCP directly. Use the same endpoint as Claude:

{
  "mcpServers": {
    "my-wordpress-site": {
      "url": "https://YOUR-SITE.com/wp-json/mcpwp/v1/mcp",
      "headers": {
        "X-API-Key": "mcpwp_YOUR_KEY"
      }
    }
  }
}

Recommended path — full tool access, same as Claude Desktop. Header-based auth keeps the key out of the URL — the more secure connect method available today.

Once connected, call wp_introspect first, then wp_onboard for a full site briefing before making changes.

GPT Actions (OpenAPI)

For ChatGPT Plus users without a Business plan, MCPWP also ships an OpenAPI 3.0 schema. Use it to connect as a custom GPT.

Go to chat.openai.com/gpts → Create a GPT
In the Configure tab → Add actions
Import schema from:

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

The schema endpoint is public — no API key needed to read it.

Set authentication:
- Type: API Key
- Auth type: Custom header
- Header name: X-API-Key
- Value: your mcpwp_ key
Save and test — the GPT will use the REST endpoints directly.
