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

{
  "mcpServers": {
    "fal-mcp": {
      "command": "uvx",
      "args": [
        "fal-mcp-server"
      ]
    }
  }
}

Abre Claude Desktop → Settings → Developer → Edit Config. Reinicia después de guardar.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "fal-mcp": {

        "fal-mcp-server"
      ]
    }
  }
}

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

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "fal-mcp": {
      "command": "uvx",
      "args": [
        "fal-mcp-server"
      ]
    }
  }
}

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

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "fal-mcp": {
      "command": "uvx",
      "args": [
        "fal-mcp-server"
      ]
    }
  }
}

Mismo formato que Claude Desktop. Reinicia Windsurf para aplicar.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "fal-mcp",
      "command": "uvx",
      "args": [
        "fal-mcp-server"
      ]
    }
  ]
}

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

~/.config/zed/settings.json

{
  "context_servers": {
    "fal-mcp": {
      "command": {
        "path": "uvx",
        "args": [
          "fal-mcp-server"
        ]
      }
    }
  }
}

Añádelo a context_servers. Zed recarga en caliente al guardar.

claude mcp add fal-mcp -- uvx fal-mcp-server

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