README

gamecalendar-mcp

Servidor MCP para la base de datos de GameCalendar (Neon Postgres). Permite a Claude consultar —y opcionalmente modificar— los datos del sitio directamente, sin pasar por la web.

Seguridad: lectura libre, escritura opt-in

  • Lectura: siempre disponible.
  • Escritura: solo si defines GAMECALENDAR_MCP_WRITE=1. Sin esa variable, las tools de escritura ni se registran (Claude no puede llamarlas).
  • delete_blog_post es destructiva y exige confirm=true explícito.
  • update_game solo toca campos editables a mano (section, score, opencritic_score, early_access, trailer); el resto lo gestiona el sync de IGDB.

Tools

Tool Modo Qué hace
list_releases lectura Juegos por sección/plataforma
search_games lectura Busca juegos por nombre
get_game lectura Ficha completa (id o slug)
list_blog_posts lectura Posts (con o sin borradores)
get_blog_post lectura Post completo por slug
db_stats lectura Resumen de la DB

Variables de entorno

Variable Obligatoria Descripción
DATABASE_URL Cadena de conexión Neon (la misma de gamecalendar)
GAMECALENDAR_MCP_WRITE no 1 para habilitar escritura

Conectarlo a Claude Code

Con el CLI (recomendado), solo lectura:

claude mcp add gamecalendar \
  --env DATABASE_URL="postgres://...neon..." \
  -- node /home/zaswear/projects/packages/gamecalendar-mcp/index.js

Con escritura habilitada, añade el flag:

claude mcp add gamecalendar \
  --env DATABASE_URL="postgres://...neon..." \
  --env GAMECALENDAR_MCP_WRITE=1 \
  -- node /home/zaswear/projects/packages/gamecalendar-mcp/index.js

O a mano, en la config MCP (~/.claude.json o .mcp.json del proyecto):

{
  "mcpServers": {
    "gamecalendar": {
      "command": "node",
      "args": ["/home/zaswear/projects/packages/gamecalendar-mcp/index.js"],
      "env": {
        "DATABASE_URL": "postgres://...neon...",
        "GAMECALENDAR_MCP_WRITE": "1"
      }
    }
  }
}

No pongas la DATABASE_URL en ningún archivo commiteado. Pásala por la config MCP (que es local) o por el entorno.

Probar sin Claude

pnpm -C packages/gamecalendar-mcp smoke          # solo lectura
pnpm -C packages/gamecalendar-mcp smoke --write  # comprueba que registran las tools de escritura

El smoke lee DATABASE_URL del .env de gamecalendar.
