STS2MCP vs csharp-sdk

STS2MCP: STS2MCP is an experimental research mod for Slay the Spire 2 that enables AI agents to play the game. It exposes game state and actions via a localhost REST API, with an optional MCP server for Claude Desktop/Claude Code integration. It supports both singleplayer and multiplayer co-op, and has been tested against STS2 v0.99.1.; csharp-sdk: The MCP C# SDK is the official C# SDK for the Model Context Protocol, designed to enable .NET applications, services, and libraries to implement and interact with MCP clients and servers. The Model Context Protocol (MCP) itself is an open protocol that standardizes how applications provide context to Large Language Models (LLMs), facilitating secure integration between LLMs and various data sources and tools.
