Yes, for developers. Organizations pay for the API when they need regression runs, a CI hook, custom test sets, audit trails or committee reports.

Do I need patient data?

No. Synthetic data only. Never send real patient records, names, dates or record numbers.

Orinyx MCP · Free for developers · Launching Oct 29

Test your healthcare AI agent against cited FDA labels.

Deterministic: no LLM in the verdict.

Orinyx MCP is an MCP server for the agents people are shipping in healthcare. Hand it the medication orders or claims your agent produced and it checks each one against the FDA label text, cites the section, and says plainly when it could not check at all.

In testing with physicians and our clinical advisor. Early access opens from this list, first come.

FLAGGED: the cited label says otherwise, at the severity shown.

SUPPORTED: consistent with the cited label text. Not a judgment that the order suits a patient.

NOT VERIFIED: Orinyx could not check it, which does not mean it is correct.

An order Orinyx cannot read as written comes back first, marked UNREADABLE, do not act on it.

Orinyx flags; the clinician decides.

Works where your agent lives

Claude Code, Claude Desktop, Cursor, any MCP host.

Local

Runs on your machine over stdio, your credential stays in your environment.

Hosted

A connector URL with sign-in, Streamable HTTP, for Claude Desktop, claude.ai and remote agents.

CI

A command-line tool with exit codes: 0 clean, 2 flagged, 3 not verified, 1 error, so a flagged claim fails the job.

At launch (Oct 29)

What it does today

Verification tools, reference lookups, scored exams.

Verify

verify_order_text for orders exactly as written, Orinyx splits them into dose, route and frequency claims; verify_medications for structured claims; get_verification, get_accuracy and export_verification for saved runs, physician-review accuracy and CSV or PDF export.

Reference

FDA OTC monograph text today. FDA prescribing-label section text, with the set ID, version and DailyMed address, arrives at launch. Reference only, never a verdict.

Exams

A scored sitting on a fixed synthetic test set: medication claims from a transcript, a reply to a patient message, or ICD-10-CM codes for an encounter note; Orinyx opens the exam for a product and the answer key never leaves the server.

Free for developers

Free for developers. Organizations pay for the API.

The MCP is free for developers: verification tools, reference lookups, sample test sets, CSV or PDF results. Organizations pay for the API when they need regression runs on model or prompt changes, a CI hook, custom test sets, audit trails or a one-page report for a hospital AI committee. Organization pricing is published at launch.

What Orinyx does not do

Read this before you wire it in.

No EHR connection. The MCP talks only to the Orinyx API. No FHIR, no Epic, no Cerner.
No real patient data. Synthetic test data only, everywhere. Claim text is stored in the audit record.
No clinical decisions. Supported means one claim agrees with the cited label text, not that the order suits a patient.
No safe by default. Abstain means unchecked, never safe.
No model in the verdict. No language model decides a verdict, a severity or a score.

Source

The MCP client is an Apache-2.0 package that holds no rules, no reference data and no verdict logic; every tool call is a REST request carrying your own credential. The source is published at launch.
