Helena Bioinformatics MCP for clinical variant interpretation, ACMG/AMP evidence and literature.

Uphealth Signal turns federally-sourced (CDC/NIH/MedlinePlus) health facts, lists, and tips into agent-callable cued-stream tools. Every cue is provenance-backed, audience-safety-checked, and sequenced on the patient's last response, so your AI health agent never fabricates health content. Free sandbox (Display mode): no PHI, no BAA. Not medical advice.

Hosted, zero-install MCP for source-provenanced US federal healthcare provider data. Resolve any NPI or CCN across NPPES, OIG LEIE, SAM.gov, state Medicaid exclusions, PECOS, Care Compare, and Open Payments — every field carries a 14-field provenance contract, with an "excluded or compromised anywhere" check on every lookup.
