Ambient Context MCP

nassie256/ambient-context-mcp

Gives Claude direct access to your Windows PC's ambient state through four privacy-gated tools: get_states for current presence/battery/foreground app type, poll_events for changes like user_returned or ac_power_connected, describe_events for the schema catalog, and get_policy for understanding what's blocked and why. Everything defaults to off for sensitive data until you opt in through the tray app's settings dialog. Runs as a single localhost process on port 37690 with bearer token auth, storing nothing except an optional events.jsonl if you enable persistence. Built for scenarios where you want Claude to adapt to whether you're at your desk, on battery, or deep in a long work session without sending anything beyond your machine.
