## Which one, for what

### Medplum (B)

Good for: An agent working inside a digital health company's own FHIR store, reading and writing patients, observations and appointments under a BAA.

Ahead on:
- Schema & documentation, 82 against 56
- Agent ergonomics, 73 against 54
- Payments & pricing, 25 against 15
- Maintenance & community, 93 against 31
- Transparency & trust, 72 against 59

Also in its favour:
- Open source

Watch for: The MCP `fhir-request` tool can delete or overwrite any resource the token allows, with no readOnlyHint or destructiveHint

### Redox (C)

Good for: Health software vendors integrating with many hospital EHRs and networks, and integration teams who want an agent to manage Redox configuration.

Ahead on:
- Reliability, 85 against 75

Watch for: The MCP server loads 107 tools in one set, including write and delete tools with no confirmation step

## Verdicts

**Medplum.** Graded on the hosted FHIR API at api.medplum.com. Rate limits, a `RateLimit` header and a 99.99 per cent SLA are published, AccessPolicy resources allow read-only clients, and an official MCP server sits in the registry. Its main tool can delete records with no annotation, the status page could not be read, and the privacy policy dates from 2022.

**Redox.** Redox connects to EHRs and clinical networks behind a FHIR API, with signed-JWT OAuth keys, a 99.95 per cent SLA, a HackerOne bug bounty and a hosted MCP server for managing integrations. The MCP server exposes 107 tools at once with write and delete tools unconfirmed, OpenAPI files sit behind login, and the sandbox plan costs $15,000 a year.

## Before you call either

### Medplum

1. Use a ClientApplication with an AccessPolicy limited to the resources the task needs, and set `readonly` where no writes are needed
2. Read the `RateLimit` header and wait for the reset time after a 429. Writes cost 100 quota points, searches 20 and reads 1
3. Create patients with conditional create (`If-None-Exist`) or upsert on an identifier so a retry doesn't make a duplicate
4. Pass paths to `fhir-request` relative to the FHIR R4 base, with no leading slash or `/fhir/R4` prefix
5. Use `Prefer: respond-async` for large bundles. Operations inside the background job don't count against the quota

### Redox

1. Name the environment in every MCP prompt and try configuration changes in staging first, as Redox advises
2. Stay under 7,500 requests per IP per five minutes, and back off exponentially on 5XX
3. Sign the token request with the private key whose public key is registered on the OAuth API key
4. Ask an organisation owner to enable the MCP server before connecting a client
5. Treat log payloads returned through MCP as PHI and as untrusted text
