## Which one, for what

### Aidbox (B)

Good for: An organisation building its own clinical data repository, EHR or payer platform on FHIR, where an agent works against that store.

Ahead on:
- Reliability, 59 against 28
- Schema & documentation, 77 against 62
- Agent ergonomics, 79 against 72
- Security & auth, 74 against 67
- Maintenance & community, 80 against 69

Watch for: No built-in rate limiting or brute-force protection, by the vendor's hardening page

### 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:
- Transparency & trust, 51 against 45

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

**Aidbox.** Graded on the FHIR REST API of an Aidbox instance the owner runs. Monthly releases, two-year LTS lines, SMART on FHIR, AccessPolicy rules and AuditEvent logging are documented, and a free development licence needs no sales call. Aidbox has no rate limiting of its own, its MCP module is alpha, and no terms of service were found on the website.

**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

### Aidbox

1. Ask the operator for a Client with an AccessPolicy limited to the task. Don't rely on the public MCP policy, which the docs mark unsafe
2. Use `If-None-Exist` on creates and conditional update on identifiers so retries don't duplicate records
3. Use `_elements` and `_count` to keep responses small, and follow the Bundle's paging links
4. Throttle yourself. Aidbox applies no rate limit, so a burst lands on the customer's database
5. Don't load real patient data into an instance on a development licence

### 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
