Discussion Topic

Hello,

I am attempting to use an AI tool (like ChatGPT or another Model Context Protocol client) to interact with a service running on an ngrok tunnel. However, the client is consistently failing to authenticate, and the server is rejecting the request.

The Error:
The server returns the following JSON response to the initial request:

{"error":{"code":-32000,"message":"Bad Request: Mcp-Session-Id header is required"},"id":"","jsonrpc":"2.0"}
