Hello,
I’m running a local MCP server using the official Python SDK (mcp, Anthropic).
The server works and exposes the MCP endpoint at:
When I try to add this endpoint inside ChatGPT under:
Apps & Connectors → Add Connector → MCP Server URL
ChatGPT rejects it with the message:
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:
Is it currently possible to connect a local MCP server (HTTP / localhost) to ChatGPT?
Does “Apps & Connectors” support MCP, or only remote HTTPS endpoints?
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.
