SUMO-MCP Server

# SUMO-MCP Server Startup Script for PowerShell # 说明： # - SUMO 需已安装 # - 推荐：在系统环境变量中设置 SUMO_HOME，并确保 $env:SUMO_HOME\bin 在 PATH 中 # - 若未设置 SUMO_HOME，本脚本将仅依赖 PATH 中的 sumo/netgenerate 等二进制 # IMPORTANT: # MCP stdio transport requires server stdout to contain ONLY JSON-RPC messages. # This script prints diagnostics to stderr only. if ($env:SUMO_HOME) { $env:PATH = "$env:SUMO_HOME\bin;$env:PATH" } else { [Console]::Error.WriteLine("WARN: SUMO_HOME not set, relying on PATH.") } $sumoCmd = Get-Command sumo -ErrorAction SilentlyContinue if (-not $sumoCmd) { if (-not $env:SUMO_HOME) { [Console]::Error.WriteLine("WARN: SUMO not found.
