Cursor utilise le même schéma mcpServers que Claude Desktop. La config projet l'emporte sur la globale.

Cas d'usage

Usages concrets : STS2MCP

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

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

Quand l'utiliser : You want to see how an AI approaches deck building and combat decisions.

Prérequis

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

Déroulement

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?✓ Copié

→ 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.✓ Copié

→ 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?✓ Copié

→ Combat analysis with recommended card play sequence

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

Pièges

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