* @briefDescription: MCP tools for web server lifecycle management and status monitoring
* @methods: startWebServer, stopWebServer, serverStatus
* @contributors: GitHub Copilot, Claude Code Agent
* @examples:
* - Start web server on port 3000 with background process management
* - Check server status and get connection information
* @vulnerabilitiesAssessment: Port validation prevents binding to system ports, background process monitoring prevents resource leaks

āļø **Configuration:**
⢠Main Port: ${config.port}
⢠Environment: ${config.nodeEnv}
⢠SSE Transport: ${config.sseTransport} ā (This needs to be 'true')
⢠Authentication: ${config.enableAuthentication}
⢠JWT Secret: ${config.jwtSecret}
⢠SSE Port: ${config.ssePort}
š© **Feature Flags:**
⢠User Auth: ${featureFlags.userAuth}
⢠SSE Transport: ${featureFlags.sseTransport} ā (DISABLED - This is the problem!)
⢠MCP Protocol: ${featureFlags.mcpProtocol}
⢠MCP Authentication: ${featureFlags.authentication} ā

⢠JWT Configuration: ${authStatus.jwtConfigured}
⢠Issuer: ${authStatus.issuer}

⢠Transport Active: ${sseStatus.transportActive ? 'ā

š§ **MCP Service Status:**
⢠Protocol: ${mcpStatus.protocolEnabled ? 'ā

⢠Authentication: ${mcpStatus.authenticationEnabled ? 'ā

⢠Tools Registered: ${mcpStatus.toolsRegistered}
⢠Security Mode: ${mcpStatus.securityMode}
š **Network Status:**

šØ **IDENTIFIED ISSUES:**
1. SSE Transport feature flag is DISABLED (sseTransport: false in config)
2. MCP Authentication is DISABLED (requires SSE transport to be enabled)
3. Environment variable SSE_TRANSPORT needs to be set to 'true'
š” **FIX COMMANDS:**
⢠Enable SSE: Set environment variable SSE_TRANSPORT=true
⢠Enable MCP Auth: Requires SSE transport to be enabled first
⢠Restart server with: $env:SSE_TRANSPORT="true"; $env:ENABLE_AUTHENTICATION="true"; npm run dev
š **Summary:**
⢠Main Server: ā
Running (Port ${config.port})
⢠SSE Server: ā Disabled by feature flag
⢠Authentication: ā ļø Partially configured (JWT ready, but SSE auth disabled)
⢠Unified Auth Config: ā
Implemented but not active due to SSE transport disabled`;
