Route clinical intent. Keep identity at the edge.
Care Router sits above Health Passport. When a lab value looks abnormal, it strips every identifier on-device and sends only an anonymized clinical intent to a Gemini agent. The agent reasons through specialty, queries a provider database, checks drug interactions, and returns a grounded referral plan. It is the first version of Somach's clinical routing rail.
Reliability as a precondition to charging for healthcare AI.
A routing agent that recommends a provider who does not exist is a liability, not a product. The submission to the Google for Startups AI Agents Challenge (Track 2: Optimize) was a measured before-to-after reliability improvement across 24 grounded scenarios — not a demo.
24-scenario grounded test suite covering happy path, adversarial input, empty-database, and PII-injection cases.
Unified the serving path and the eval path onto one ADK Runner so what we test is exactly what we ship.
Every provider name must come verbatim from a tool result. Hallucinated names went from 16 to 7 across the eval set.
Agent refuses dosing and diagnostic queries before calling any tools — checked on every request, not just when convenient.
MongoDB Atlas reached natively via Model Context Protocol over stdio — selectable via USE_MONGODB_MCP=1.
10 credential-free reliability tests run on every change so reliability is a regression check, not a one-time demo.
The scoreboard.
Privacy bridge: data stays local, actions happen in the cloud.
Five steps. Zero cloud identity.
The stack.
gemini-2.5-flash, env-configurable for local and production parity.
Agent Development Kit v2. One root_agent, one Runner, one code path for serving and eval.
Provider database with vector + text search. Drug interaction collection.
MongoDB MCP server over stdio via ADK MCPToolset. Selectable alongside direct FunctionTools.
Serves the web interface and the on-device-to-cloud bridge.
Stateless, scale-to-zero deployment. No server to maintain between requests.
Try the live demo.
The demo runs against a seeded SF Bay Area provider directory. No account needed. All inputs are anonymized before reaching the agent.
