Building a Halo Infinite MCP App with Claude Code

I demonstrate a practical way to build a Model Context Protocol app for Halo Infinite, bringing match statistics, career progression, and medal details into a chat interface. The walkthrough follows the build and testing process, including how I use agent skills and existing code and documentation to refine the implementation.

- MCP app setup: adapting an agent skill and scaffolding a Halo-focused server
- Authentication and implementation: Xbox sign-in, reference code, and troubleshooting
- Testing the interface: retrieving career, service record, and match data for different players

This is for developers exploring MCP apps, agent-assisted coding, or Halo API integrations. You’ll see how to start with open-source examples and documentation, then test and iteratively improve a focused app; the coverage centers on this Halo use case rather than a general survey of MCP apps.
