"servers": {
"swiss": {
"command": "npx",
"args": ["-y", "mcp-swiss"]
}
}
}
}
```
Or add to `.vscode/mcp.json` in your workspace (shareable with your team):

### Any MCP Client
`mcp-swiss` uses **stdio transport** and requires no environment variables. The universal config:
```json
{
"command": "npx",
"args": ["-y", "mcp-swiss"]
}
```
This works with any MCP-compatible client — just plug it in.
### Docker
```bash
docker pull vikramgorla/mcp-swiss
```
Use with any MCP client that supports Docker-based servers. The container uses stdio transport:
```bash
# Run directly (stdio)
docker run -i vikramgorla/mcp-swiss
# Use with Claude Desktop
```
For Claude Desktop, update your config to use Docker:
```json
{
"mcpServers": {
"swiss": {
"command": "docker",
"args": ["run", "-i", "--rm", "vikramgorla/mcp-swiss"]
}
}
}
```
Also available on GitHub Container Registry:
```bash
docker pull ghcr.io/vikramgorla/mcp-swiss
```
