Installation

Quick Start

npx mcp-swiss

That's it. No API keys, no .env files, no accounts. Pick your client below and paste the config.

One-Click Install (.mcpb)

.mcpb bundles work with Claude Desktop and any MCP Bundle-compatible app.

⬇ Download mcp-swiss.mcpb

Open the downloaded file — your app handles the rest. No config editing, no terminal, no API keys.

Claude Desktop

Edit your config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

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

Restart Claude Desktop after saving.

Claude Code (CLI)

claude mcp add swiss -- npx -y mcp-swiss

That's it — Claude Code will use it in your next session.

Cursor

Requires Cursor 0.45.6+

Option A: Project config — create .cursor/mcp.json in your project root:

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

Option B: Global config — create ~/.cursor/mcp.json:

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

Option C: Via Cursor Settings UI

1. Open Cursor Settings
2. Go to Features → MCP Servers
3. Click + Add new global MCP server
4. Paste the JSON config above

VS Code (GitHub Copilot)

One-click Install

CLI Install

# VS Code
code --add-mcp '{"name":"swiss","command":"npx","args":["-y","mcp-swiss"]}'

# VS Code Insiders
code-insiders --add-mcp '{"name":"swiss","command":"npx","args":["-y","mcp-swiss"]}'

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"]
    }
  }
}

| Preset | Modules | Tools | Token Savings | |--------|---------|-------|---------------| | commuter | transport, weather, holidays | 14 | 81% | | outdoor | weather, avalanche, hiking, earthquakes, dams, snow | 19 | 75% | | business | companies, geodata, post, energy, statistics, snb | 24 | 67% | | citizen | parliament, voting, holidays, news | 17 | 77% | | minimal | transport | 5 | 93% | | full | all 21 modules (default) | 76 | — |

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