LockIn MCP▲116I was tired of how bad distraction blockers are so I built my own. LockIn lets AI assistants (Claude, ChatGPT, Cursor, etc.) block websites by editing the system hosts file directly via MCP tools (via a secure cloudflare bridge). Why? Because chrome extensions don't work. Blocking it natively makes it unbypassable, and having your agent gatekeep your focus is the ultimate cheat code. Since everyone is using AI agents nowadays, but most people start scrolling or Reddit while waiting for Claude Code to finish, giving them control over your focus solves that. The MCP server exposes four tools:…

I'm a solo dev. A few years ago, I got addicted to Reddit. Spent months in that loop. Being a programmer, I thought I'd be clever. Redirected Reddit's domain to nowhere in my DNS file. Worked great until I'd just... open the file and undo it 20 minutes later. So I made it irreversible. Locked the DNS file so it can't be edited unless I boot my Mac in safe mode. And if I do that, there's a script that instantly locks it again. Haven't used Reddit since last year. Problem solved, right? Wrong. I just replaced Reddit with Twitch and YouTube.

The solution concerns work/life balance. Many procrastinate during working hours, getting distracted by entertainment content and social media, or work on work-related sites during their free time instead of resting. This extension helps control work/life balance by setting time limits for accessing websites. Simply put, it's a Website Blocker with a focus mode and a timer.

Since I no longer access…
