ClinicalTrials.gov Explorer turns the live 500K-study U.S. clinical-trials registry into a single Claude-native research surface. Ask a natural-language question — "Phase 3 oncology trials by sponsor this year", "recruiting trials within 50 miles of me", "plain-English eligibility for NCT05012345" — and Claude writes a short program that hits the ClinicalTrials.gov v2 API directly, filters and joins the results, and answers. Built on a "code mode" architecture: three MCP tools instead of dozens, an indexed BM25 search over the API and field dictionary, and a sandboxed TypeScript runtime where Claude's code executes without network, filesystem, or process access. Free to use. No login. No PII collected.

The body is wrapped as async (ctgov) => { <your code> } and must return a JSON-serializable value. Read-only: the SDK only exposes GET endpoints. No network/fs; only ctgov.* methods, console.*, and standard globals are available.execute.
