LockIn MCP

LockIn MCP is a distraction-blocking tool integrated with AI assistants, built by the team behind Poke, where users tell their AI to block distracting websites and the tool enforces system-level blocks across all browsers and applications. System-level blocking persists across browsers, private windows, and device restarts via hosts file modification, AI integration works with Claude, ChatGPT, Perplexity, Cursor, and other MCP-compatible agents, and task-aware filtering via a Chrome extension allows only work-relevant sites during an active focus session. One-minute setup installs via a single terminal command, timed exceptions let users request temporary unblocks when genuinely needed, and the tool supports macOS, Windows, and Linux.
