STS2MCP vs deepseek-pp

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.; deepseek-pp: DeepSeek++ is a browser extension for Chrome, Edge, and Firefox that injects native-style tool calling, an MCP tool system, long-term memory, skill presets, and automated task scheduling into the DeepSeek web interface. It intercepts the SSE response stream in real time to execute tool calls transparently, giving DeepSeek persistent cross-session memory and agent-like automation without API access.
