1. Overview
ChatGPT consumes your MCP server via the MCP-over-HTTP transport (or, for older setups, a Custom GPT action that wraps the same tools).
2. Prerequisites
A running MCP server (chapter 3) reachable at a public HTTPS URL (chapter 4 explains Cloudflare Tunnel).
3. Configure ChatGPT
manifest.json json
{
"name": "WordPress MCP",
"mcp": {
"url": "https://your-tunnel.trycloudflare.com/mcp",
"transport": "http",
"auth": { "type": "bearer", "token": "${MCP_TOKEN}" }
}
}4. Run your first tool
Open a new chat with the configured MCP app. Ask: "List the 5 most recent posts." ChatGPT calls posts.list through your server.
