AI Tools

MCP tools from ImOnFHIR’s open-source repositories, run here in your browser from a pinned copy. They are free, read-only and use synthetic data only. The tool makes no network request of its own; your settings go in the page address, so a link reproduces the result.

Two ways ImOnFHIR's tools run

Some run in your browser. Others run on our servers when your assistant calls them. Each way gains something and risks something.

The tools on this page run in your browser.

In your browser

  • Running the tool sends nothing you entered. It runs from a copy of its code held in this site.
  • A shared link carries your settings in the address. Opening it sends that address, settings included, to our host.
  • Only tools packaged to run in the browser work this way.
  • The tool itself runs no AI. Use your own assistant on the result if you want one.

On our servers, through your assistant: the site's MCP endpoint (/api/v1/mcp)

  • You get ImOnFHIR's validator, its standards feed, its compare tools and a rule-evidence lookup. Your assistant reads the results.
  • What you send reaches our server. If your assistant runs on a provider's servers, that provider receives it too. How long that provider keeps it is the provider's policy, not ours.
  • Synthetic data only. Never send real patient data.
  • Our code logs one line per call: the tool name and the status. What our host and the validator host log is not stated (see Privacy).
  • Each call counts against a per-IP limit of 120 a minute for the endpoint, lower for some tools. The limit is kept in memory on each server instance, so it is not a hard global cap.
  • The route is configured for at most 60 seconds per call.
  • An assistant can misstate a result. The tool's own output is the source of truth.
  • The AI Tools catalog has no hosted path yet. Only the site's own tools run on our servers.
