Perplexity AI is stepping into a new era of intelligent computing on the Mac. Its latest update introduces support for Anthropic’s Model Context Protocol, or MCP, allowing the app to interact directly with the files, apps, and services installed on your device. This is a major breakthrough in AI usability, especially for those who rely on MacBooks for both personal and professional productivity. Perplexity is no longer limited to just answering questions using the internet. With MCP, it can now perform system-level actions like searching through Apple Notes, setting up reminders, scanning databases, and even sending emails on your behalf, using the data that already lives on your machine.
This new feature is currently available through local MCP support. What this means is the AI will operate within the confines of your device, without relying on external cloud servers or internet authentication. That makes it not only faster but also more secure. The data never leaves your machine, giving users confidence that their private documents, images, or internal databases are not being shared externally. For now, this functionality is exclusive to paid subscribers, but Perplexity has confirmed plans to expand remote MCP access in the future, which will bring even broader capabilities by connecting to data hubs like Google Drive, GitHub, and others.
Setting up the new system is simple but requires an additional app called the Perplexity Helper. This is necessary because apps on the Mac App Store operate inside their own isolated environments due to Apple’s privacy rules. Once the helper app is installed, users can activate MCP inside Perplexity by configuring a connector through the app’s settings. After setup, the AI is ready to operate as your on-device assistant. You can issue commands or ask it questions that involve accessing files or interacting with apps, and it will carry them out in real-time.
Anthropic’s MCP was first introduced in November 2024 as an open-source protocol to standardize how AI systems interact with data hubs. Its introduction in the Perplexity Mac app marks a practical first step in that vision becoming reality. This is not just another chatbot update. It is a shift toward AI tools that blend into the operating system itself, becoming an extension of how users get things done every day.
What makes this especially significant is the direction it points to. In the coming months, Perplexity users could expect to perform complex tasks like summarizing folders full of PDFs, automating file sorting, sending scheduled messages, or cross-referencing notes with browser history all through voice or text prompts. These were once jobs that required multiple apps, some scripting, and a lot of manual effort. Now, they may soon be handled with a single query.
As AI continues to evolve, tools like Perplexity are bringing that evolution to the devices we already use daily. The integration of Anthropic’s MCP shows just how close we are to truly intelligent personal assistants ones that can think, retrieve, act, and adapt to our needs without compromising privacy.
