From the repository
Prefix your MCP server command with envmcp. Use npx envmcp or install globally with npm install -g envmcp. Specify an optional custom env file with --env-file (or -e) flag. Example: npx envmcp --env-file .env my-mcp-server $DATABASE_URL. In MCP client config, change the command to npx and arguments to ["envmcp", "your-mcp-server", "$VARIABLE"].
