Hathor

Hathor is an autonomous clinical reasoning agent for cross-border vaccination reconciliation. A child arrives in Egypt with a Nigerian (or Sudanese, Syrian, Yemeni…) vaccination card; Hathor reads the card, resolves trade-name combinations to canonical antigens, checks every dose against the destination schedule, and emits a visit-by-visit catch-up plan — all with the agent deciding its own tool path, no hardcoded pipeline. Built on the Claude Agent SDK with eight in-process MCP tools and two safety loops: a per-field vision gate (anything < 0.85 confidence routes to clinician HITL review) and a per-recommendation rules-engine gate (a deterministic Python WHO-DAK validator vetoes any clinical claim before it reaches the UI or FHIR bundle). The clinician retains final authority and every override is logged to a FHIR Provenance resource. No open-source tool exists for autonomous cross-schedule reconciliation today; the closest prior work (AI-VaxGuide, arXiv 2507.03493) is single-country Q&A.
