LockIn MCP

Editing the system hosts file directly is the part I like, no bypassable extension layer. Does the MCP server run fully locally so the block holds even with no network, and where does the blocklist/focus-schedule config actually live: a local file I can reuse across machines, or tied to an account? And if the agent or MCP process dies mid-block, does the hosts file get cleanly restored, or could I get stuck locked out until I edit it by hand?

I've lost more focus sessions to "just open a private window" than I'd admit. Hosts file blocking is the first thing that actually closes that loophole. Does the daemon need to stay running for temp-unblocks to expire, or is that handled on the OS side? Congrats on the launch!

Using MCP as the interface so the AI controls focus mode is clean. The agent that already knows your context can decide when you're drifting. MCP's stateless nature creates interesting session continuity challenges for tracking focus blocks. Does LockIn persist focus state across server restarts? And how do you handle the OS permission model for app blocking across platforms?

using MCP for this is a clever application. most MCP tools are focused on productivity and data access, using it for focus management is an unexpected angle. the "no bypassing" part is key because the whole reason chrome extensions fail is that you can just disable them in 2 seconds when willpower drops. does the agent enforce the block at a system level or is there still a way to override it if you really need to?

This should be so much higher! Literally the BEST distraction blocker I've ever used! Feels so much more natural than those other bs chrome extensions.

The hosts-file move is the actual unlock, every extension-based blocker dies the second you remember you can just toggle it off. And triggering it from an MCP command is smart, you're already in the agent so there's no dashboard to open and "accidentally" get sucked into. For demon mode I usually just full-screen one window and kill every tab, but I bypass my own willpower constantly, so something I can't easily undo is the real appeal here. Building on MCP myself, good to see more land in that space 👊

Huge congrats on shipping, Mil! Context-switching is the absolute killer of momentum. When deep into system integrations or complex API mapping, opening a separate dashboard just to block distractions usually creates another vector for getting side-tracked.Shifting that control layer natively to the agent via an MCP command is a massive workflow upgrade. Since the agent handles the block natively, is it possible to chain this to specific tasks? For instance, instructing the agent to keep social domains locked until a specific script finishes executing or a local build passes?Excited to test out this direct-to-system approach!

Hey Product Hunt,

I built Lockin MCP because every other focus app is cooked. They all have too much UX friction; you have to open some bloated dashboard, click three buttons, and adjust a slider, and by the time you do all that, you've already opened a new tab and wasted two hours.

LockIn avoids all of this. You lock yourself out via a single MCP command or text. It edits your system hosts file directly. No bloat, no easy bypasses, just instant focus.

Excited to see you guys try it. How do you handle distractions when you need to go demon mode?
