Connect Lexifye to your AI

Two separate things, and they are easy to confuse. DeepSeek is the AI itself — the model that does the thinking and the writing. The DeepSeek Harness is the program you actually sit in front of: a free, open-source workspace that installs on your own computer — Windows, Mac or Linux — and opens in your browser, much like ChatGPT's window, except it is yours. The harness talks to the model on one side and to us on the other.

Why do it this way? Because it is the cheapest way to use Darash, Junifye and Lexifye. You pay DeepSeek directly for the model — cents per conversation, and only for what you use — and nothing more to anyone else beyond your Publifye subscription. There is no monthly AI fee stacked on top. As with any hosted AI, your conversations are sent to DeepSeek's servers to be answered.

A caution and a compliment, both earned. The Harness is **new and still in development** — DeepSeek themselves call it a preview and say things will change between versions, so expect the occasional rough edge. It is also one of the most talked-about tools of the year: more than 180,000 people starred it on GitHub within a fortnight of its release, mostly for how far it bends to fit whatever you point it at. Promising and fast-moving — not yet settled.

1. Get your DeepSeek key first. Register at deepseek.com, top up a small amount — $5 goes a long way — and copy the API key it gives you. This pays for the model.
2. Buy your Publifye access. Open the Lexifye store below, log in or create an account, and buy Lexifye Access — or the Complete Trio if you want Darash, Junifye and Lexifye together on one key. Your API key appears in your account as soon as the purchase goes through.
3. Install Node.js from nodejs.org — version 22 or newer. It brings npm, which you need next. The harness will not start on anything older.
4. Open a terminal — PowerShell on Windows (press Start, type PowerShell, hit Enter), or Terminal on Mac and Linux — and run the first command below. It fetches and starts the harness and opens it in your browser, and asks for your DeepSeek key the first time. Run that same command every time you want to use it, and leave the window open while you work: closing it shuts the harness down.
5. Hand it the MCP endpoint and your Publifye key, exactly as shown below. The harness writes its own connector — you never edit a file. Open a new chat afterwards, because tools load when a chat starts.

Keep it fresh. Because it changes often, run one of the commands below every few weeks instead of the usual one. The `@latest` is what tells it to fetch the newest version. Nothing else changes — your connectors and your keys stay exactly as they are.

Do this once per service — Darash, Junifye and Lexifye each get their own connector, and the same Publifye key works for all three.

That is the whole setup — from here it should just work. One thing worth doing straight away: the harness runs on your own machine, so it opens in your browser at a local address such as http://127.0.0.1:3080. Bookmark that address the first time it appears. It is how you get back in later, and nobody else can reach it — it lives on your machine, not on ours.

Choose DeepSeek's Pro model rather than Flash. Darash's Hebrew and Greek work is noticeably better on it, and the difference shows most on close exegetical questions.

Hours of study for about a dollar. DeepSeek's Pro model bills roughly $0.66 per million input tokens and $1.98 per million output off-peak, and double that at peak — peak is 03:00–06:00 and 08:00–12:00 Oslo time in summer (02:00–05:00 and 07:00–11:00 in winter). Work after midday and top up a few dollars at a time. DeepSeek sets the rates; check their pricing page for what they are today.

One honest note. The DeepSeek Harness and DeepSeek's models are other people's software — Publifye does not build, maintain or support them, and cannot take responsibility for how they behave or change. This is simply a route we have tried and found works well. What we stand behind is our own side of it: the MCP endpoint and your Publifye key.

In Claude, add a custom connector and paste the URL above. Most clients need only the URL — they register themselves automatically (Dynamic Client Registration is live).

If a client asks for a Client ID, use the value above and leave the client secret blank.

One command adds the connector to Claude Code:

Point any MCP client at the endpoint below. It speaks OAuth 2.1 — clients discover the authorization server automatically (RFC 9728 protected-resource metadata).
