In my last post, I discussed Perplexity's aim to transform the familiar blinking web we've known for decades. It brings to mind the early days of Google, when many questioned the need for another search engine since AltaVista already did a good job. Although Comet appears to be just another Chromium-based web browser, the AI powering the browser under the hood has the same disruptive potential as Google's PageRank algorithm once did.

Perplexity's new AI-powered Comet web browser, initially exclusive to Max subscribers at $200 monthly, is now accessible to Pro subscribers for $20. I tested it and am impressed—both by Perplexity's hypocrisy and Comet's truly innovative browsing experience. This post shares my rant against Perplexity, while my next post will praise Comet, the first browser on the battlefield in the new browser war.

The key new feature in the just-released AI Shell Preview 6 is run_command_in_terminal, among several new built-in tools that allow the AI model to run commands and review outputs directly in your PowerShell terminal. Additionally, AI Shell now supports local and remote MCP servers, transforming it into a versatile AI assistant across Windows, Mac, and Linux.

The ChatGPT Gmail connector was first released in June 2025 for Plus, Pro, Team, Enterprise, and Edu users. However, because of alleged data protection rules, users in the European Economic Area, Switzerland, and the UK were excluded. OpenAI is now deploying connectors for Gmail, Google Calendar, Google Drive, and GitHub across Europe for all plans—notably after Anthropic released their MCP connectors weeks ago in Europe without such concerns, suggesting OpenAI's initial data protection claims were merely pretextual or that MCP has no priority status for the AI company. The announcement mentions Google Contacts, but this connector isn't yet accessible in my ChatGPT with a Plus plan. I tested the Gmail Connector, and following GPT-5's disastrous launch, it appears OpenAI released another flop immediately afterward.

In my previous post, I covered Microsoft’s new Edge Copilot Mode, introducing only one significant change. However, shifting Copilot from the sidebar to the center in Edge is more than just a design update. Microsoft’s move marks the first strategic step in the unfolding new browser war involving Google, OpenAI, and Perplexity—companies that exploit broad 'fair use' claims to harvest web content for their own greedy gain. But the upcoming battles aren’t just about who controls the web’s entry point—it could signal the beginning of the end of the web as we know it. The fall of Google’s dominance as the web’s central policymaker now seems inevitable. Once the dust settles from the new browser war, a decentralized web shaped by independently communicating AI agents might emerge. Think that’s far-fetched? Keep reading.

In Edge Copilot Mode, announced a few days ago, Copilot shifts from being just an AI assistant to becoming the main browser interface. Now front and center in Microsoft's browser, Copilot has evolved into a serious ChatGPT competitor. In this post, I explain how to enable Edge Copilot Mode and discuss whether it introduces any new features compared to the previous version of Copilot in Edge.

Windows-MCP is an open-source MCP server that enables AI agents to control the Windows operating system, supporting tasks such as file navigation, application launching, and GUI automation. It features mouse/keyboard input tools, clipboard management, and window and app state detection. I tested Windows-MCP, one of the extensions listed in Anthropic Claude Desktop that can be installed using the free plan.

Reports indicate that ChatGPT Agent Mode might be capable of solving CAPTCHAs, which are often the final line of defense against persistent bots like AI crawlers on many websites. However, these claims originate from Reddit, known for the frequent hallucinations of its users. To verify, I decided to test it myself.

The new ChatGPT Agent Mode combines the Operator's ability to browse and interact with websites with Deep Research's ability to analyze and synthesize information from multiple sources. I tested ChatGPT's Agent Mode and was quite disappointed. Honestly, I find it surprising that OpenAI made this feature available to the public, considering that they have led the way with their chatbot so far. In my view, ChatGPT's Agent Mode is a flawed concept because it forces an AI agent to use a web browser, a relatively primitive tool designed for inferior human intelligence.

I tested three MCP servers in Anthropic Claude Sonnet 4: Claude Gmail Search, Zapier Gmail MCP server, and GongRzhe’s Gmail MCP Server. I also submitted the same search prompt to Gemini in Gmail. The results varied greatly. Only two AI tools passed my test, one failed, and the most promising MCP server turned out to be useless.

Anthropic has introduced two new concepts for connecting AI models to resources through MCP: desktop extensions and connectors. Extensions are available only on Claude Desktop (Windows and Mac), while connectors are supported on both the desktop and the Claude.ai web app. All desktop extensions are local MCP servers, but not all local MCP servers qualify as extensions. Conversely, all remote MCP servers are considered connectors; however, not all connectors are remote MCP servers. Although some theoretical documentation about these new concepts exists, I mainly categorized them based on how Claude Desktop organizes the different types of MCP servers.

VS Code version 1.102 introduced several useful new features in GitHub Copilot. Command allow/deny lists let you specify which commands the Copilot agent can execute without asking for permission. The resubmit feature enables you to edit a previous request and resubmit the prompt. Additionally, the new VS Code version includes various updates for managing MCP servers, including a curated catalog of MCP servers.

A new study by METR got a lot of attention online. It claims that developers often overestimate the productivity boost from AI tools. In a coding test, the researchers found that AI caused a 19% "slowdown" for developers. In my opinion, it's not AI coding that's overhyped, but rather the study's findings.

The number of GitHub Copilot concepts continues to grow, and their similar names can easily confuse. This post offers an overview of all the concepts, along with a link to find more information. The main confusion stems from the Copilot tools on GitHub.com and GitHub Copilot in VS Code. Although there is some overlap, keeping these two areas separate is essential.

Microsoft Azure MCP Server allows AI agents like VS Code GitHub Copilot in Agent Mode to communicate with your Azure resources through natural language prompts. Azure MCP Server supports services such as Storage, Cosmos DB, Key Vault, and Logs.

Google's new Gemini CLI allows up to 60 model requests per minute and 1,000 daily requests. Professional developers might hit these limits quickly, but many IT admins will find the free plan sufficient. Compared to Anthropic Claude Code and OpenAI Codex CLI, I find Google's open-source AI-powered terminal more useful for the AI-augmented admin.

The brand-new Warp 2.0 no longer wants to be just an AI-powered terminal. The Warp team appears to be taking inspiration from Anthropic’s Claude Code and OpenAI’s Codex CLI. Both AI-driven coding tools target devs who prefer to code in a terminal instead of working in an Integrated Development Environment (IDE). Zach Lloyd, Warp's CEO, is eager to join the AI agent race, believing that features like the Agent Management Panel, diffs, and a built-in editor can transform a CLI tool into a vibe coding platform or what he calls an Agentic Development Environment (ADE).

Recently, leading AI companies announced support for remote MCP, allowing an MCP client to connect to a remote MCP server via Streamable HTTP, which still supports Server-Sent Events (SSE). The Streamable Data Input/Output (SDIO) protocol remains essential for local integrations and remote services, which are accessible only through conventional APIs. In my opinion, the excitement surrounding new model releases has lost its significance. AI model developers seem to primarily focus on optimizing their models for AI benchmarks. However, the genuine innovations occur in the technologies surrounding AI models—most notably in AI agents and the supporting infrastructure in which remote MCP servers will play an important role.

The VS Code May 2025 update (version 1.101), released a few days ago, introduces a range of new features primarily focused on GitHub Copilot. My favorite addition is the custom chat mode, which lets you create a personalized mode alongside the built-in options: Ask, Edit, and Agent. In this post, I'll also explore the new chat tool sets and the undoing edits feature. While the Simple Browser feature was included in the previous release, it deserves discussion. Furthermore, I will briefly summarize the MCP enhancements.
