Relay is a working household replanning prototype with a hosted browser simulation and an actual local Streamable HTTP MCP server.
Try the simulation: https://codeforcode111.github.io/relay-household/
The corrected 2:12 English walkthrough uses public-domain Piper LJSpeech narration and snapshots captured from the running local MCP demo. It is labeled as a snapshot walkthrough and includes narration and captions. The household is fictional; no real Alexa device, calendar or messaging service is connected.
Validation: 27 application tests, 18 tests in the separate MCP Tool Check project, and 12 ordered contract checks against Relay passed. The actual MCP session negotiated protocol 2025-11-25. CI passed on Node 22 and 24.
