📌 **Building a Proxy Model Context Protocol (MCP) in Node.js** with Justin Meyer

This talk walks through the process of building a **proxy Model Context Protocol (MCP)** in **Node.js** to support downloading attachments from Jira. MCPs are a key part of enabling AI assistants to fetch contextual information from tools like Jira, and building a proxy allows you to handle data access flexibly without relying on frontend workarounds.

Along the way, we’ll explore how the OAuth 2.0 Authorization Code Flow with **PKCE** works in practice, and how to implement it to enable context-aware tools. This is a hands-on walkthrough for developers looking to integrate model context systems with real-world platforms using standard web technologies.

By the end, you’ll understand how to set up an MCP proxy service, walk through the complete authorization lifecycle, and apply these patterns to your own context-fetching services.
