/**
* TMB Bus MCP Server Host
*
* This host application starts the MCP server as a child process.
* In production, you would typically configure this in your MCP client's config file.
*
* For Claude Desktop, add to your config file:
*
* macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
* Windows: %APPDATA%\Claude\claude_desktop_config.json
*
* {
* "mcpServers": {
* "tmb-bus": {
* "command": "node",
* "args": ["/path/to/tmb-bus-mcp/dist/server.js"],
* "env": {
* "TMB_APP_ID": "your_app_id",
* "TMB_APP_KEY": "your_app_key"
* }
* }
* }
* }
