Household Recall Watch MCP server

Recall Radar — an MCP server and voice front end for "has anything in my house been recalled?"

A self-hosted Model Context Protocol server that lets a voice assistant answer household safety questions from public government recall data:

• US product recalls (CPSC) and home medical-device recalls (FDA),
• US food recalls (FDA),
• US medicine recalls (FDA) and EU medicine shortages (European Medicines Agency),
• EU dangerous-product alerts (EU Safety Gate, formerly RAPEX),
• and a household watchlist the assistant checks proactively: "has anything I own been recalled since the summer?"

Every answer carries a short spoken sentence for the voice reply, plus structured detail with the source URL and date of every item. No API keys, no accounts, no LLM needed to run it.

Built for the Amazon Developer Hackathon, Alexa+ track. MCP spec 2025-11-25, Streamable HTTP, stateless, @modelcontextprotocol/sdk 1.30.1.

This is a simulated smart-display experience backed by a real MCP server; it has not been connected to an Alexa+ device. See the judge-run guide, the verification record and the friction log.

Not medical or safety advice. Recall and shortage data can be incomplete or late. Always check

the linked notice, and ask a pharmacist, doctor or the manufacturer before acting. Never stop a

prescribed medicine on your own.

Run it (one command)

Node 20 or newer. One process serves the MCP server at /mcp, the voice UI at / and the agent at POST /api/ask:

npm ci && npm start
# recall-radar MCP server: http://127.0.0.1:3000/mcp (health: /healthz, ...)
# Recall Radar voice UI:   http://127.0.0.1:3000/  (agent: POST /api/ask, model: Scripted mode, no LLM)

Judge path.

no LLM*: a fixed phrase-to-tool mapping stands in for the model, but the MCP calls and the recall data are real and live. Try the suggestion chips, or drive it from the URL: http://127.0.0.1:3000/?q=Watch%20my%20crib%20mattress&q=Has%20anything%20in%20my%20house%20been%20recalled%3F

1. No key, scripted mode. npm start, open . The badge reads *Scripted mode,

identifies the selected model (gpt-6-luna by default). This path was run live on 2026-10-02 with that model; other models were not exercised (EVIDENCE.md).

1. With a model. Set OPENAIAPIKEY outside the repository and run npm start. The badge

docker build -t recall-radar-mcp . && docker run --rm -p 3000:3000 recall-radar-mcp
docker run --rm -p 3000:3000 -e OPENAI_API_KEY recall-radar-mcp   # with a model
