Provides an Alexa+ voice interface for medication management and family care coordination. Enables elderly users to log doses, record check-ins, send family messages, and request help via voice, while caregivers can retrieve AI-written digests, adherence reports, and alerts.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@CareCircle MCP Server how is Aai doing today?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
An Alexa+ MCP server that helps older parents take their medicines safely and quietly keeps their children in the loop.
Track: Alexa+ (self-hosted MCP server, spec
2025-11-25, Streamable HTTP) Mini challenges: AWS Builder (Bedrock, DynamoDB, SNS, Lambda, EventBridge Scheduler) Β· Open Source (MIT)
In India alone, about 150 million people are over 60. Many of them live on their own while their children work in other cities or abroad. Most take 3β5 medicines a day, and roughly half of patients with chronic conditions don't take their medicines as prescribed. The result is missed doses, accidental double doses and avoidable hospital visits. Meanwhile, the son in Bengaluru keeps calling and asking "Aai, did you take your tablet?" and still doesn't really know how she's doing.
Pill-reminder apps don't work for this person. They need a smartphone, small text and tapping through screens. A voice in the kitchen does work.

Aai just talks to Alexa the way she talks to anyone:
Aai says | CareCircle does |
"Good morning" | Reads today's plan, delivers a voice message from her daughter, asks how she slept |
"I took my sugar tablet" | Matches the spoken name to Metformin 500 mg and logs the 8:30 AM dose, then updates the pill count |
"I took my metformin" (again) | π Double-dose guard: "Wait, you already took it at 8:40. Please don't take another one." The family gets an urgent alert |
"I'm feeling a bit lonely" | Records a check-in. After the third low-mood day in a row, it asks her children to call |
"Tell Priya to bring vegetables" | Sends the message to her daughter by SMS or email |
"I feel dizzy, I need help" | Alerts everyone at once and suggests 112 if it sounds like an emergency |
Her son asks his own Alexa "How is Aai doing today?" and gets a short AI-written digest in English, Hindi or Marathi. Urgent items come first, then medicines, mood, refills and the next doctor visit.
This runs after every interaction and every 30 minutes through EventBridge Scheduler:
Missed dose: not confirmed 3 hours after the scheduled time
Repeated misses: 2 in a row of the same medicine β urgent
Silence signal: no interaction at all by 11 AM
Low-mood trend: 3 low check-ins in a row, or a sharp drop from her usual mood
High pain: 7/10 or more
Refill forecast: days of stock left per medicine, with alerts at 5 days and 2 days
Skipped dose, including the reason she gave ("felt dizzy")
CareCircle never gives medical advice or changes doses. It coordinates care and leaves clinical decisions to doctors.

Stateless Streamable HTTP (a fresh server and transport per request), so it scales horizontally on Lambda. It validates Origin and requires a Bearer token.
Alexa+ web simulator. Until an Alexa+ developer preview is available to everyone, / serves an Echo-Show-style simulator with voice in and out (Web Speech API, en-IN). It works as a real MCP client: it connects to /mcp over Streamable HTTP and lets Amazon Bedrock (Converse + tool use) choose and call the tools. If Bedrock isn't configured, a deterministic intent router takes over, so the demo also runs offline. The MCP inspector panel shows every tools/call live. A demo clock lets you jump to 8:40 AM, 12:30 PM or 8:45 PM to see the time-based logic.
