- src/index.ts:1423-1459 (handler)Main handler for the 'dhis2_get_audit_summary' tool. Retrieves audit summary from auditLogger, adds session info, logs the call, and returns formatted text response.case 'dhis2_get_audit_summary': const summary = auditLogger.getAuditSummary(); const permissionSummary = PermissionSystem.getPermissionSummary(userPermissions); auditLogger.log({ toolName: name, parameters: {}, outcome: 'success', dhis2Instance: dhis2Client?.baseURL, userId: currentUser?.username, executionTime: Date.now() - startTime }); return { content: [{ type: 'text', text: `š DHIS2 MCP Server Audit Summary š¢ **Usage Statistics:** ā¢ Total Operations: ${summary.totalOperations} ā¢ Successful: ${summary.successCount} (${Math.round((summary.successCount / summary.totalOperations) * 100) || 0}%) ā¢ Errors: ${summary.errorCount} (${Math.round((summary.errorCount / summary.totalOperations) * 100) || 0}%) š¤ **Current Session:** ā¢ User: ${currentUser?.displayName || 'Unknown'} ā¢ Permission Level: ${permissionSummary.level} ā¢ Available Tools: ${PermissionSystem.filterToolsByPermissions(tools, userPermissions).length} of ${tools.length} ā¢ Connected to: ${dhis2Client?.baseURL || 'Not connected'} š ļø **Most Used Tools:** ${summary.mostUsedTools.slice(0, 5).map(tool => ` ā¢ ${tool.tool}: ${tool.count} times`).join('\n') || ' ā¢ No operations yet'} ${summary.recentErrors.length > 0 ? `ā ļø **Recent Errors:** ${summary.recentErrors.slice(0, 3).map(error => ` ā¢ ${error.toolName}: ${error.error}`).join('\n')}` : 'ā No recent errors'}` }] };
