#### Manual Config

Add to your VS Code User Settings (JSON) — press Ctrl+Shift+P → Preferences: Open User Settings (JSON):

{
  "mcp": {
    "servers": {
      "swiss": {
        "command": "npx",
        "args": ["-y", "mcp-swiss"]
      }
    }
  }
}

Or add to .vscode/mcp.json in your workspace (shareable with your team):

{
  "servers": {
    "swiss": {
      "command": "npx",
      "args": ["-y", "mcp-swiss"]
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/model_config.json:

{
  "mcpServers": {
    "swiss": {
      "command": "npx",
      "args": ["-y", "mcp-swiss"]
    }
  }
}

Cline (VS Code)

Open VS Code settings.json and add:

{
  "cline.mcpServers": {
    "swiss": {
      "command": "npx",
      "args": ["-y", "mcp-swiss"]
    }
  }
}

Any MCP Client

mcp-swiss uses stdio transport and requires no environment variables. The universal config:

{
  "command": "npx",
  "args": ["-y", "mcp-swiss"]
}

This works with any MCP-compatible client — just plug it in.

Docker

docker pull vikramgorla/mcp-swiss

Use with any MCP client that supports Docker-based servers. The container uses stdio transport:

# Run directly (stdio)
docker run -i vikramgorla/mcp-swiss

# Use with Claude Desktop

For Claude Desktop, update your config to use Docker:

{
  "mcpServers": {
    "swiss": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "vikramgorla/mcp-swiss"]
    }
  }
}

Also available on GitHub Container Registry:

docker pull ghcr.io/vikramgorla/mcp-swiss

Module Filtering

By default, mcp-swiss loads all 21 modules (76 tools). For better token efficiency, load only the modules you need:

Select specific modules

{
  "mcpServers": {
    "swiss": {
      "command": "npx",
      "args": ["-y", "mcp-swiss", "--modules", "transport,weather"]
    }
  }
}

Use presets

{
  "mcpServers": {
    "swiss": {
      "command": "npx",
      "args": ["-y", "mcp-swiss", "--preset", "commuter"]
    }
  }
}

Combine preset + modules: --preset commuter --modules parliament

List available: npx mcp-swiss --list-modules or npx mcp-swiss --list-presets
