## Verdicts

**Metriport Medical API.** One network query pulls a patient's records from HIEs, pharmacies and labs and returns deduplicated FHIR, with per-operation rate limits, RFC 7807 errors and AGPLv3 source. Each API key has full access with no scopes, there are no public prices, and the sandbox opens only after Metriport approves the account.

**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

### Metriport Medical API

1. Check the `errors` array after Start Network Query. It returns 2XX even when some sources fail
2. Wait for `network-query.*` webhooks or poll Get Network Query Status before reading consolidated data, which is cached from the last query
3. Send the resource's `eTag` in `If-Match` on updates to avoid overwriting newer data
4. Keep patient creates under 15 a minute and network queries under 20 a minute per source
5. In sandbox, create patients whose first name matches a pre-defined persona to get example records

### 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
