What problem does it solve?
Health and research builders waste hours manually browsing ClinicalTrials.gov when agents could not query the registry natively.
Who is it for?
Indie builders validating health-tech ideas who want registry-grounded answers inside Claude Code or Cursor.
Skip if: Teams that need HIPAA-covered patient records, offline-only research, or guaranteed medical eligibility decisions without human review.
What do I get? / Deliverables
Your agent can cite live trial listings and results while you draft scopes, landing copy, or matching prototypes.
- Structured trial search results inside agent chats
- Retrieved study results for competitive and indication research
- Trial shortlists aligned to eligibility-style prompts
Recommended MCP Servers
Journey fit
Canonical shelf in Idea because trial discovery and eligibility research happen before you commit to a health-tech build or positioning. Research subphase fits structured study search, results retrieval, and trial matching used to validate markets and clinical narratives early.
How it compares
Public-trials data MCP integration, not a clinical decision skill or EHR connector.
