agent-protocol vs STS2MCP
agent-protocol: The Agent Protocol provides a single common interface for communicating with AI agents, addressing the challenge of diverse agent interfaces and simplifying comparison. It is a tech-stack agnostic API specification, enabling easier development of devtools and fostering ecosystem growth by reducing boilerplate.; 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.
