Your Question

MCP newbie here. I'm trying to build a Google Drive MCP server. I followed the latest MCP spec and followed the steps to implement OAuth 2.1 and SSE transport. However, I keep running into Unauthorized errors when I try to test it via MCP Inspector.

Does anyone know of a good example of a remote MCP server implementing OAuth and being tested with either an MCP client or MCP Inspector? Looking at an example would be very helpful
