I compared six frontier AI models—DeepSeek V3, Anthropic Claude Sonnet 3.7, Google Gemini 2.5 Pro, Meta Llama 4 Maverick, OpenAI GPT 4o (GPT 4.1), and Mistral Large 2—in terms of their capabilities in interacting with MCP servers. Surprisingly, the performance in terms of accuracy, token usage, and API costs are quite different..

For security purposes, it may be beneficial to restrict Active Directory account logins to regular working hours. These logon times can be configured using the calendar widget in Active Directory Users and Computers (ADUC). However, PowerShell provides a more efficient and flexible alternative, particularly because it offers reporting capabilities that the graphical interface does not.

The Docker Model Runner is a beta feature available in Docker Desktop 4.40 for macOS that enables you to run open-source AI models, including DeepSeek, Llama, Mistral, and Gemma, locally on Macs with Apple Silicon (M1 to M4). Support for Windows with NVIDIA GPU acceleration is expected to be released by the end of April 2025.

LLMs' knowledge cutoff date is a significant issue, often resulting in outdated responses. Some frontier models can browse the web, but they frequently skip this ability because they think they can handle things on their own. Bringing in an MCP server that can search the web helps the AI stay updated and assist it when struggling with a problem. Tavily is a research search engine designed to summarize online content for AI models. In this post, I will guide you through installing the Tavily MCP server on Windows. Installing on a Mac follows a similar process.

Playwright is an open-source framework by Microsoft for automating web browsers to perform end-to-end testing, scraping, and UI interactions across Chromium, Firefox, and WebKit. The Playwright MCP server lets AI agents like GitHub Copilot control a web browser using Playwright’s automation capabilities. Microsoft introduced support for MCP in Visual Studio Code 1.99 (March 2025), enabling tools like the Copilot Agent to connect with external services. In this post, I explain how to install the Microsoft Playwright MCP server in VS Code for the GitHub Copilot Agent.

Since Group Policy changes remain a cornerstone of centralized Windows system management, admins should know which settings have been introduced or changed before an OS upgrade. Windows 11 adds not only policies for its latest features but also extends configuration options for many existing components.

In March 2025, the release of VS Code version 1.99 introduced support for Anthropic's Model Context Protocol (MCP) in GitHub Copilot's Agent Mode. This open standard is now backed by leading AI companies such as Google, Amazon, Microsoft, and OpenAI. MCP provides a standardized framework that allows AI models to interact with external tools and data sources. In this post, I will guide you on how to install, start, stop, activate, and deactivate MCP servers. You will also learn to configure settings in mcp.json and settings.json, as well as import MCP servers from Claude Desktop, Cline, and Roo Code.

DNSSEC is a security standard that protects the Domain Name System by ensuring only authorized servers can respond to DNS queries. Microsoft's DNS server has supported DNSSEC zone signing for some time. However, to take full advantage of DNSSEC, client systems must also be configured, typically via Group Policy, to request authentic responses.

In Visual Studio Code release 1.99, Microsoft introduced GitHub Copilot’s Agent mode, a feature that closely resembles functionalities previously offered by Cursor, Cline, and Roo Code. Agent mode lets Copilot examine the codebase, find relevant files, make edits, and autonomously run and debug code. In this post, I’ll compare Agent mode with Ask and Edit mode and outline how Agent mode facilitates vibe coding—the automation of writing code.

ScriptRunner is a PowerShell-based IT automation platform that streamlines, delegates, and monitors various management tasks through a no-code web interface and a comprehensive script library. It ensures secure operations with strict user and system access controls, comprehensive policies, and full-activity auditing. Version 7.2 introduces approval workflows for script execution, enabling administrators to configure authorization groups and track pending requests, adding a governance layer beneficial for organizations with strict compliance requirements.

The AI tools for the Command Line Interface (CLI) we discussed on 4sysops connect the terminal to AI models. For example, the Warp terminal includes AI tools designed to help admins working on a CLI. The Windows CLI MCP Server does the opposite. If you missed it, the Model Context Protocol (MCP) is a new open standard for AI agent communication with software services created by Anthropic and backed by OpenAI, Amazon, and Microsoft. With MCP, your primary interface is the chatbot, and for the Windows CLI MCP Server, shell access is an additional tool the AI can utilize. The Windows CLI MCP Server supports PowerShell, CMD, Git Bash shells, and remote SSH.

Have you ever received the notice stating, "Additional security updates can be applied with ESM Apps" after logging into an Ubuntu Linux machine? Despite working with Ubuntu for 15 years, this was the first time I encountered it. Since this was a relatively new installation of Ubuntu 24.04, I was perplexed as to why I couldn't install all security updates using apt upgrade. After some investigation, I discovered I was using Ubuntu Standard, while only Ubuntu Pro qualifies for all security updates. I felt annoyed and deceived because my system had no uncommon packages, and everything I installed came from the Ubuntu repository. This means that, in most cases, a fresh installation of the latest Ubuntu Linux LTS release does not receive all critical security updates.
