What Is Yargı PRO (Yargı MCP)? Connecting Turkish Case Law and Legislation to Your AI Assistant: Setup, Pricing and Desktop App

When you ask Claude or ChatGPT a legal question, the assistant may write decisions from its own memory; it can make up citations or quote text incorrectly. Yargı PRO closes this gap: it connects to your assistant via MCP (MCP is a type of connection that lets an AI use an outside service). Once connected, the assistant searches Yargı PRO's decision and legislation database based on your question, returns the decision it finds with its citation and full text, and builds its interpretation on that.

Coverage (official source): decisions of the Court of Cassation (Yargıtay), the Council of State (Danıştay), regional appeals courts and local courts (the README says about 11 million decisions), the Constitutional Court (AYM), the European Court of Human Rights (AİHM), 12 types of legislation, the Official Gazette of Turkey and, on the Pro plan, decisions of 18 institutions (Competition Board, KVKK, BDDK, SPK, Court of Accounts, KİK, GİB private tax rulings…).

Who it's for: lawyers, law firms and in-house legal teams who research case law and legislation with an AI assistant. Yargı PRO is an independent product not affiliated with the Turkish Ministry of Justice, UYAP (Turkey's judicial e-system) or e-Devlet (Turkey's e-government portal).

First you create an account at yargipro.com (with email). Then you add a single address to the assistant you use; on first connection the assistant opens the Yargı PRO sign-in and permission page in your browser. If the desktop app is installed, it can also connect to seven apps, such as Claude Desktop, Codex and Antigravity, in one click.

Once connected, you don't need to type tool names; you ask in plain language and the assistant calls the right Yargı PRO tool itself. The requests below are based on examples from the Yargı PRO user guide.

Skills may not always kick in on their own. The user guide's tip: start your request with "Using Yargı PRO skills"; e.g. "Using Yargı PRO skills, calculate the appeal deadline." The user guide lists 107 skills (criminal, civil, enforcement, administrative, Constitutional Court, ECtHR).

On Solo and higher plans, the desktop app connects to UYAP and UETS (Turkey's national electronic notification system). You choose the case, and the documents download from UYAP to the case folder on your computer using your own e-signature; documents with text (UDF, Word, PDF with a text layer) are converted into text the AI can read. In an assistant that works with folders, such as Codex or Claude Code, you open this folder and work on the files.

!On October 8, 2026, UYAP announced that it would block access if it detects unusually heavy activity from AI tools or bot software (Yargı PRO FAQ). The app downloads at intervals, and if restriction notices repeat, it stops and asks for confirmation; still, the access decision is UYAP's.

Yargı PRO doesn't sell an AI model; it connects to the assistant you already use. Based on your subscription, the user guide suggests this pairing: Claude subscription → claude.ai / Claude Desktop, ChatGPT subscription → Codex, Gemini subscription → Google Antigravity.

You can also connect a model running on your computer (e.g. LM Studio); the user guide notes that small models use tools poorly and results need to be verified. On enterprise accounts, MCP requests can also be made with an API key instead of OAuth.

The Solo and Pro amounts are discounted prices valid until December 31, 2026; the list prices are TRY 1,499 (≈ $30) and TRY 3,899 (≈ $78). For law firms there is a 12-month membership per user; the amount isn't listed on the page; for a quote, use the "Buy annual for your firm" link on the pricing page. Payment is taken by credit card through PayTR, the subscription renews automatically, and monthly subscriptions have no commitment. Dollar amounts are approximate, at the TCMB rate of November 4, 2026.

The user guide's account page describes a different flow: it says new accounts start on a free plan with hourly and daily search quotas, and that upgrading to a paid plan is requested through support, not the dashboard, for now. The homepage and pricing page, however, describe the 14-day Pro trial; which one is current is not clear in official sources. After signing up, check in the dashboard which plan you started on; to upgrade, write to info@yargipro.com.

Official pricing page last checked on November 3, 2026.

The user guide separates two layers: Yargı PRO searches a real database and returns the real text; the assistant reads, summarizes and interprets that text. Made-up decisions or misquotes arise in the assistant layer. The three habits the user guide recommends:

1. 1Check the tool card: If the answer doesn't show that the search tool was used, say "Don't write from memory; search with the yargi tools and rely only on the decisions you retrieve."
2. 2Have the citation verified: Give back the docket/decision number and have it fetch the full text. If the decision doesn't exist, the tool can't find it.
3. 3Compare the quote with the text: Say "Show me, verbatim from the decision's text, the paragraph where this phrase appears."

!Yargı PRO and this page are not legal advice. Confirm every decision and article you put in a petition against the official source (decision text, legislation, the Official Gazette), and check the last day of any deadline calculation against the legislation.

!Documents sit on your computer as unencrypted files; if your Documents folder syncs with OneDrive or iCloud, the documents go to that service too. Yargı PRO recommends turning on disk encryption (FileVault, BitLocker).

1. 1On app.yargipro.com, open dashboard › "My subscription".
2. 2Cancel the subscription; you keep using it until the period ends. If you change your mind, you can resume before the period ends.
3. 3Also remove the connection in your assistant (in Claude: Customize› then Connectors› then Yargı PRO› then Uninstall).

The full cancellation, refund and withdrawal terms are in the Cancellation and Refund and Distance Sales texts under yargipro.com/yasal.

Yes. Yargı MCP was an open-source project that connected Turkish court decisions to assistants. On October 28, 2026, the saidsurucu/yargi-mcp repository on GitHub was reduced to a migration notice: the free hosted address yargimcp.surucu.dev was shut down and no longer works. The same connection continues in Yargı PRO at https://app.yargipro.com/mcp. Said Sürücü is Yargı PRO's technology co-founder.

The repository now contains only the migration notice; whether the old open-source code is distributed elsewhere is not clear in official sources. Before using an old copy, check its source and maintenance yourself.

If you added the old address to your assistant, remove it and connect with the new address through a Yargı PRO account. Guides to the same developer's other open-source MCP projects that connect to Turkish data:

Borsa MCP: connecting BIST, TEFAS and KAP data (Turkish stock market and fund data) to your assistant →

İhale MCP: having your assistant search EKAP (Turkey's public procurement platform) tenders →

YÖK Tez MCP: searching Turkish theses with your assistant →
