Cursor usa el mismo esquema mcpServers que Claude Desktop. La configuración del proyecto prevalece sobre la global.

Haz clic en el icono MCP Servers de la barra lateral de Cline y luego en "Edit Configuration".

}

Mismo formato que Claude Desktop. Reinicia Windsurf para aplicar.

Continue usa un array de objetos de servidor en lugar de un mapa.

Añádelo a context_servers. Zed recarga en caliente al guardar.

Un solo comando. Verifica con claude mcp list. Quita con claude mcp remove.

Casos de uso

Usos del mundo real: STS2MCP

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

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

Cuándo usarlo: You want to see how an AI approaches deck building and combat decisions.

Requisitos previos

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

Flujo

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?✓ Copiado

→ 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.✓ Copiado

→ 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?✓ Copiado

→ Combat analysis with recommended card play sequence

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

Errores comunes

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