Integration details

Description

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.

Tools

3 tools agents can invoke

Return doc entries for study-data fields by exact `path` or by `prefix`. Useful for discovering nested field names before projection. Field reference: https://clinicaltrials.gov/data-api/about-api/study-data-structure.
Run a short async body against the `ctgov` SDK in a secure sandbox to query the public ClinicalTrials.gov v2 API (https://clinicaltrials.gov/data-api/api). 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.
Search the ClinicalTrials.gov SDK surface (see https://clinicaltrials.gov/data-api/api). Returns a TypeScript snippet describing the most relevant endpoints and study fields for your query. Use this before writing code for `execute`.

ClinicalTrials.gov Explorer (by BLEN) FAQ

How do I improve a Community connector's discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
