LockIn MCP
Let AI block distractions when you need to focus.
What it does
Trigger system-level focus sessions and website blocks instantly using natural language prompts within AI clients. Enforce absolute network-level restrictions by directly editing local host configurations across all installed browsers. Maintain task-aware filtering to block unrelated pages while permitting access to project-critical references. Manage time-limited temporary unblocks and AI-managed exceptions without manual dashboard configurations.
Why it works
Leverages the open Model Context Protocol to transform distraction-blocking into an inline capability of AI assistants. Bypasses fragile browser extensions by enforcing absolute system-level network blocks via local host files. Eliminates administrative setup fatigue by removing bloated standalone dashboards and complex sliders. Provides natural language flexibility to handle scheduling, temporary exceptions, and context-aware filtering seamlessly.
