## Which one, for what

### Health Gorilla (C)

Good for: US providers, labs and digital health companies that need network record retrieval and lab ordering through one FHIR API with a QHIN behind it.

Ahead on:
- Reliability, 58 against 28
- Schema & documentation, 80 against 62
- Transparency & trust, 61 against 51

Watch for: No public prices. Fees are set case by case and the sandbox is requested by form

### Medblocks (D)

Good for: A consumer or care app, or an assistant, that needs a patient's own records from US hospitals and payers with the patient's consent, and wants an MCP route as well as REST.

Ahead on:
- Payments & pricing, 25 against 5
- Maintenance & community, 69 against 63

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No status page, SLA or published rate limits for the Platform API

## Verdicts

**Health Gorilla.** A TEFCA QHIN with a FHIR R4 API, OpenAPI fragments on every reference page, idempotency keys on POST and dated weekly release notes. Access is sales-led, with case-by-case fees, a sandbox by request and no published rate limit numbers, and the API terms allow access to be cut at any time.

**Medblocks.** Patient-authorised record retrieval with a ten-tool remote MCP server, OAuth with per-capability consent, an audit entry for every call and a free plan for 1,000 active patients. No status page, no published rate limits and no idempotency keys were found, and the OpenAPI file behind the reference is not published.

## Before you call either

### Health Gorilla

1. Send a fresh UUID in `HG-Idempotency-Key` on every POST and reuse it only when retrying the same payload
2. Poll async operations no sooner than the `Retry-After` value and treat 454 as an expired result
3. Follow `link.relation=next` in Bundles rather than building offsets yourself
4. Expect mocked Patient360 data in sandbox unless network connectivity is enabled for the tenant
5. Log `X-HG-Request-Id` from each response for support cases

### Medblocks

1. Connect with `claude mcp add --transport http medblocks https://app.medblocks.com/mcp` and sign in, or send a workspace API key as a Bearer token from a backend
2. Ask the person before calling `disconnect_health_system` or `delete_person`. Both are permanent
3. Wait for the connection webhook or check connection status before reading records. Pulls run in the background after the patient approves
4. Branch on `error.code`, not the message, and wait the `Retry-After` seconds on a 429
5. Use a Sandbox workspace and the Synthetic Hospital (password `demopass`) for tests. Sandbox keys cannot reach production sources
