There's basically a couple of different ways to implement an MCP server - for this demo it's a local binary that communicates over stdio, so no OAuth process is taking place. It's only meant to run on your local machine.

To make the demo simpler to explore and understand, the binary loads it's configuration (SnapTrade API client id, secret, and username and secret) from a .env file that you populate with your credentials which allows it to fetch the right data.

Totally understand why it’s not in the post, and it did help me understand mcp more. That said, that’s the issue: most articles I’ve seen are geared toward how to do a local-use-only mcp. In the ones I want to build I need to deploy into an enterprise and know the current user and am not quite clear how yet. The answers on using oauth help though. Maybe a future post idea :)
