## Which one, for what

### 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:
- Agent ergonomics, 72 against 49
- Security & auth, 67 against 32

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

### ROOK (C)

Good for: A wellness, insurance, corporate wellness or remote monitoring product that wants normalised wearable data pushed to its backend, with plan prices it can see up front.

Ahead on:
- Reliability, 75 against 28
- Schema & documentation, 74 against 62

Watch for: Credentials are one client UUID and secret per environment, sent by Basic auth, with no scopes or rotation documented

## Verdicts

**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.

**ROOK.** Graded on the REST API. A public OpenAPI file, a free Sandbox from the self-serve portal, published plan prices and a dated changelog. Credentials are one client UUID and secret per environment with no scopes, 429 handling isn't documented, the API is meant for occasional queries rather than bulk reads, and no SOC 2 report or security contact was found.

## Before you call either

### 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

### ROOK

1. Send HTTP Basic auth with client_uuid as the username and the secret key as the password, plus a User-Agent header, or the WAF returns 403
2. Use https://api.rook-connect.review for Sandbox and https://api.rook-connect.com for production. Each has its own credentials
3. Read health data from the data webhook. Use the API only for occasional queries, and stay under 60 requests a minute
4. Deduplicate summaries on document_version and datetime. ROOK resends a summary with a higher document_version when it changes
5. Call POST /api/v1/user_id/{user_id}/data_sources/revoke_auth to end a connection. Some providers take hours to stop sending data
