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
