Hello,  
I’m running a **local MCP server** using the official Python SDK (`mcp`, Anthropic).  
The server works and exposes the MCP endpoint at:

```auto
http://localhost:8000/mcp

```

When I try to add this endpoint inside ChatGPT under:

**Apps & Connectors → Add Connector → MCP Server URL**

ChatGPT rejects it with the message:

```auto
Unsafe URL

```

My ChatGPT account does **not** have the “Developer Tools → MCP Servers” menu that some documentation mentions. I only have the “Apps & Connectors (Beta)” section.

### **My questions:**

1. Is it currently possible to connect a **local MCP server** (HTTP / localhost) to ChatGPT?

2. Does “Apps & Connectors” support MCP, or only remote HTTPS endpoints?

3. If ChatGPT cannot connect to localhost, what is the correct way to test MCP locally — should I implement my own MCP client or host the server publicly over HTTPS?

My goal is to have an AI (ChatGPT) call MCP tools such as a Selenium test via my local MCP server. Any clarification on the current limitations or correct workflow would be appreciated.
