OpenSpartan Forerunner MCP Server

🪐 MCP server for Halo Infinite. The openspartan forerunner mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 7 defined tools rather than through you.

What it actually does

Forerunner is a custom-built local MCP server that allows you to connect to your Halo Infinite data through whatever MCP client you're using.

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

Its toolset

Everything the assistant can do here goes through one of these:

• opsp_api_endpoints — Returns a JSON-formatted list of all available endpoints that exist in the Halo Infinite REST API surface
• opsp_my_service_record — Returns the complete Halo Infinite player service record for matchmade games for the currently authenticated player. This tool does not have the
• opsp_my_latest_matches — Returns the stats for a player's latest Halo Infinite matches. This includes all match types, such as matchmade games, custom games, and LAN games
• opsp_exchange_list — Lists all of the items that are currently available on the Halo Infinite exchange
• opsp_my_gear_configuration — Returns Halo Infinite customizations with their images for the authenticated user
• opsp_my_career_rank — Returns the player's current Halo Infinite career rank (or level) and progress to the top level (Hero). The player earns experience with every match
• Authentication — Once you add the tool to your MCP client, you will be prompted for your Microsoft Account (MSA) credentials. This is your Xbox Live account that you

Configuration

• .NET 9 SDK

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the openspartan forerunner mcp server does with a few real requests.

When to reach for it

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. OpenSpartan Forerunner's toolset — opsp_api_endpoints, opsp_my_service_record, opsp_my_latest_matches and 4 more — is a fair guide to whether it matches your workflow. It is maintained by dend; worth a glance at recent repository activity before you build anything load-bearing on it.
