STS2MCP vs agent-droid-bridge

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.; agent-droid-bridge: Agent Droid Bridge is an MCP server that connects AI agents to Android devices and emulators over ADB. It exposes ADB functionality as structured tools for mobile automation, app testing, dynamic analysis, and reverse engineering.
