Installieren

Wählen Sie Ihren Client

~/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"
      ]
    }
  }
}

Öffne Claude Desktop → Settings → Developer → Edit Config. Nach dem Speichern neu starten.

~/.cursor/mcp.json · .cursor/mcp.json

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

Cursor nutzt das gleiche mcpServers-Schema wie Claude Desktop. Projektkonfiguration schlägt die globale.

VS Code → Cline → MCP Servers → Edit

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

Klicken Sie auf das MCP-Servers-Symbol in der Cline-Seitenleiste, dann "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

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

Gleiche Struktur wie Claude Desktop. Windsurf neu starten zum Übernehmen.

~/.continue/config.json

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

Continue nutzt ein Array von Serverobjekten statt einer Map.

~/.config/zed/settings.json

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

In context_servers hinzufügen. Zed lädt beim Speichern neu.

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

Einzeiler. Prüfen mit claude mcp list. Entfernen mit claude mcp remove.

Anwendungsfälle

Praxisnahe Nutzung: STS2MCP

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

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

Wann einsetzen: You want to see how an AI approaches deck building and combat decisions.

Voraussetzungen

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

Ablauf

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?✓ Kopiert

→ 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.✓ Kopiert

→ 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?✓ Kopiert

→ Combat analysis with recommended card play sequence

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

Fallstricke

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

Kombinationen

Mit anderen MCPs für 10-fache Wirkung

sts2mcp-2 + filesystem

Log game states and decisions for analysis and strategy improvement

Log every decision point and our choice to ~/sts2/run-log.json for later analysis.✓ Kopiert

Prüfen: Check the game's mod manager for STS2MCP

Can't connect to API

The server starts on localhost:15526 when the mod loads. Ensure the game is running with the mod enabled.
