설치

클라이언트 선택

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "sts2mcp-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/Gennadiyev/STS2MCP"
      ]
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config 열기. 저장 후 앱 재시작.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "sts2mcp-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/Gennadiyev/STS2MCP"
      ]
    }
  }
}

Cursor는 Claude Desktop과 동일한 mcpServers 스키마 사용. 프로젝트 설정이 전역보다 우선.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "sts2mcp-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/Gennadiyev/STS2MCP"
      ]
    }
  }
}

Cline 사이드바의 MCP Servers 아이콘 클릭 후 "Edit Configuration" 선택.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "sts2mcp-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/Gennadiyev/STS2MCP"
      ]
    }
  }
}

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "sts2mcp-2",
      "command": "TODO",
      "args": [
        "See README: https://github.com/Gennadiyev/STS2MCP"
      ]
    }
  ]
}

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

~/.config/zed/settings.json

{
  "context_servers": {
    "sts2mcp-2": {
      "command": {
        "path": "TODO",
        "args": [
          "See README: https://github.com/Gennadiyev/STS2MCP"
        ]
      }
    }
  }
}

context_servers에 추가. 저장 시 Zed가 핫 리로드.

claude mcp add sts2mcp-2 -- TODO 'See README: https://github.com/Gennadiyev/STS2MCP'

한 줄 명령. claude mcp list로 확인, claude mcp remove로 제거.

사용 사례

실전 활용법: STS2MCP

How to have Claude play a run of Slay the Spire 2

👤 STS2 players curious about AI strategy ⏱ ~60 min beginner

언제 쓸까: You want to see how an AI approaches deck building and combat decisions.

사전 조건

STS2 with the mod installed — Download STS2_MCP.dll and .json to <game>/mods/, enable mods in settings
MCP server running — Server auto-starts on localhost:15526 when mod loads

흐름

Start a run

Start a new Slay the Spire 2 run. Check the game state — what character are we playing and what's our starting deck?✓ 복사됨

→ Character info, starting deck, and current map
Make strategic decisions

We're at a card reward screen. Analyze the options based on our current deck and suggest the best pick.✓ 복사됨

→ Analysis of each option with recommendation
Handle combat

We're in combat. Show me our hand, the enemies, and their intents. What's the optimal play order?✓ 복사됨

→ Combat analysis with recommended card play sequence

결과: A complete STS2 run with AI making strategic decisions.

함정

AI makes suboptimal decisions without full game knowledge — Provide context about game mechanics and synergies the AI may not know
