OpenSpartan Forerunner

Overview

The OpenSpartan Forerunner MCP server is a local bridge that lets AI assistants such as Claude pull real‑time Halo Infinite data directly from a user’s Xbox Live account. By exposing the game’s REST API surface through the Model Context Protocol, developers can embed rich Halo statistics and configuration data into conversational agents without writing custom integrations. This eliminates the need for third‑party services or manual data export, keeping all credentials on the local machine and ensuring privacy.

For developers building AI‑powered tools that need up‑to‑date game metrics, Forerunner offers a suite of ready‑made tools. Each tool corresponds to a specific API endpoint: from listing all available REST endpoints () to retrieving the authenticated player’s full service record, latest match stats, gear configuration, and career rank. The server also exposes the Halo Infinite Exchange inventory via . Because every tool is defined in plain JSON and follows the MCP specification, AI clients can invoke them with simple prompts like “Show my latest match outcomes” or “What’s on the Exchange today?” and receive structured responses that can be parsed or displayed directly in a chat UI.

The server’s design prioritizes security and simplicity. Authentication is handled locally through the Microsoft Account login flow; no tokens leave the user’s machine, and cached credentials are used only for Xbox Live and Halo REST calls. This makes it safe to run in shared or cloud environments while still providing full access to the user’s personal data. Developers can integrate Forerunner into any MCP‑compatible workflow—be it a VS Code extension, Claude Desktop, or custom tooling—by simply pointing the client to the executable.

In practice, Forerunner enables a variety of use cases: a game‑streaming overlay that auto‑updates player stats, an AI coach that analyzes recent matches to suggest gear changes, or a career‑tracking dashboard that visualizes rank progression. Because the data is fetched live from Halo’s own APIs, users receive accurate, real‑time insights without manual effort. The combination of a lightweight local server, MCP compatibility, and comprehensive Halo Infinite coverage makes Forerunner a powerful asset for developers looking to fuse AI assistants with gaming data.
