Perplexity is an AI search engine that answers questions by combining real-time web results with conversational, natural language responses. Installing Perplexity's official MCP server on your Mac or Windows PC allows querying Perplexity from any AI model in VS Code GitHub Copilot. Enabling your AI to search the web for the latest updates is a must-have feature for scripting or working in the terminal.

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..

Si vous faites partie des 97% de dev à grosses lunettes qui utilisent des assistants IA comme GitHub Copilot, Windsurf ou Cursor, ce que vous allez lire va probablement flinguer votre journée…

Et oui parce que si vous pensiez que votre assistant IA préféré était votre meilleur atout pour coder, sachez que des chercheurs en sécurité viennent de découvrir qu’en réalité, tous ces outils pourraient se comporter en cheval de Troie placé directement dans votre IDE. Et le plus flippant c’est que vous ne verriez absolument rien venir, même en scrutant le code ligne par ligne.

LLMs' knowledge cutoff date is a significant issue, often resulting in outdated responses.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.

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.

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.

Zapier is a cloud-based automation platform that lets users connect and automate workflows between thousands of web services without coding. Recently, Zapier announced support for Anthropic's MCP standard. MCP is an open protocol that allows AI models to interact with external tools, data sources, and services, and it's now also supported by OpenAI, Microsoft, and Amazon. In this post, I share my experiences with Zapier's MCP server.
