Before you connect

Patient data: Do not use this server with protected health information (PHI). We do not sign HIPAA Business Associate Agreements (BAAs). See Terms, Health data.

The login page asks for your Infermedica App-Id and Infermedica App-Key.

Find both values in the Infermedica Developer Portal → Applications. They are used only to call the API on your behalf and to derive a private account id.

Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Infermedica App-Id and Infermedica App-Key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Example prompts

Turn on the Infermedica connector, then ask in plain words. The AI picks the tools.

FAQ

Is this an official Infermedica product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Infermedica. The server calls the Infermedica API with your own Infermedica access, so it sees only the data that your account can see.

Can I use this server with patient data (PHI)?

No. Do not use this server with protected health information (PHI). We do not sign HIPAA Business Associate Agreements (BAAs). See Terms, Health data.

What do I need to connect?

The login page asks for your Infermedica App-Id and Infermedica App-Key. See Before you connect for where to find them.

Do I put my Infermedica key or an Authorization header in the client config?

No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Infermedica App-Id and Infermedica App-Key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my Infermedica credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Infermedica API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Infermedica.

Can the AI change my Infermedica data?

All 17 Infermedica tools are marked read-only.

What does it cost?

The Free plan gives 100 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls, for this Infermedica server only. Run infermedica_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run infermedica_upgrade: it returns a Stripe Checkout link. To cancel, run infermedica_cancel_subscription. Pro continues to the end of the paid period.

What if a Infermedica tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with infermedica_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
