#Requires -Version 5.1 <# .SYNOPSIS Wrapper script to run MCP Memory HTTP Server in background with logging and restart logic. .DESCRIPTION This script is designed to be executed by Windows Task Scheduler. It runs the HTTP server with proper environment setup, logging, and automatic restart on failure. .NOTES File Name : run_http_server_background.ps1 Prerequisite : Python, uv package manager Location : scripts/service/windows/ #> # Configuration $ErrorActionPreference = "Stop" $ScriptDir = Split-Path -Parent $MyInvocation.MyCommand.Path $ProjectRoot = (Get-Item "$ScriptDir\..\..\..").FullName $LogDir = Join-Path $env:LOCALAPPDATA "mcp-memory\logs" $LogFile = Join-Path $LogDir "http-server.log" $PidFile = Join-Path $env:LOCALAPPDATA "mcp-memory\http-server.pid" $MaxRestarts = 3 $RestartDelaySeconds = 60 # Ensure log directory exists if (-not (Test-Path $LogDir)) { New-Item -ItemType Directory -Path $LogDir -Force | Out-Null } # Logging function function Write-Log { param([string]$Message, [string]$Level = "INFO") $Timestamp = Get-Date -Format "yyyy-MM-dd HH:mm:ss" $LogMessage = "[$Timestamp] [$Level] $Message" Add-Content -Path $LogFile -Value $LogMessage # Keep log file under 10MB if ((Get-Item $LogFile -ErrorAction SilentlyContinue).Length -gt 10MB) { $OldLog = "$LogFile.old" if (Test-Path $OldLog) { Remove-Item $OldLog -Force } Rename-Item $LogFile $OldLog } } # Load .env file function Load-EnvFile { $EnvFile = Join-Path $ProjectRoot ".env" if (Test-Path $EnvFile) { Write-Log "Loading environment from $EnvFile" Get-Content $EnvFile | ForEach-Object { if ($_ -match '^\s*([^#][^=]+)=(.*)$') { $Name = $matches[1].Trim() $Value = $matches[2].Trim().Trim('"').Trim("'") [Environment]::SetEnvironmentVariable($Name, $Value, "Process") } } } else { Write-Log "No .env file found at $EnvFile" "WARN" } } # Check if server is already running function Test-ServerRunning { if (Test-Path $PidFile) { $StoredPid = Get-Content $PidFile -ErrorAction SilentlyContinue if ($StoredPid) { $Process = Get-Process -Id $StoredPid -ErrorAction SilentlyContinue if ($Process -and $Process.ProcessName -like "*python*") { return $true } } } # Also check via HTTP health endpoint try { $Response = Invoke-WebRequest -Uri "http://127.0.0.1:8000/api/health" -TimeoutSec 2 -UseBasicParsing -ErrorAction SilentlyContinue if ($Response.StatusCode -eq 200) { return $true } } catch { # Server not responding } return $false } # Main execution Write-Log "========== MCP Memory HTTP Server Starting ==========" Write-Log "Project Root: $ProjectRoot" Write-Log "Log File: $LogFile" # Check if already running if (Test-ServerRunning) { Write-Log "Server is already running.
