## 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 50
- Security & auth, 67 against 30

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

### Validic Inform (C)

Good for: A remote patient monitoring or wellness app that needs normalised readings from many wearables and home devices, and an agent that wants to start building without a sales call.

Ahead on:
- Reliability, 73 against 28
- Schema & documentation, 75 against 62
- Payments & pricing, 40 against 25
- Maintenance & community, 74 against 69
- Transparency & trust, 71 against 51

Watch for: The organisation token is sent as `?token=` in the URL, the only documented option

## 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.

**Validic Inform.** Graded on the Inform REST and Streaming APIs. An agent can create a free developer account through a sign-up API, with only an emailed code needing a person's inbox, and llms.txt plus agent guides document every step. The organisation token travels in the URL query string, the free tier holds synthetic data only, and production access needs an Enterprise contract.

## 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

### Validic Inform

1. Show the developer the free-tier terms and wait for acceptance before calling `POST /auth/register`
2. Send `Authorization: <id_token>` to sign-up calls, but pass the organisation token as `?token=` on Inform calls
3. Use the customer `uid` in URLs, never Validic's internal `id`, which returns a silent 404
4. Keep date ranges to 30 days or less and page month by month for backfills
5. Unwrap `data` on list responses and treat an empty array as normal on a new account
