Chistara MCP server — Iranian legal corpus · سرور MCP چیستارا

Chistara (چیستارا, hoghogh.ai) is an AI legal assistant for Iranian law. This MCP server gives Claude, ChatGPT, Codex, Perplexity and any other MCP client the same verified legal corpus and calculators that power the Chistara app: 70,000+ statute articles and notes, 50,000+ court rulings, the Judiciary's advisory opinions, official circulars, yearly official rates and procedural deadlines, and 14 legal calculators. Every result carries a source_url on hoghogh.ai, so the assistant can cite the exact article or ruling instead of answering from memory.

چیستارا دستیار حقوقی هوش مصنوعی برای قوانین ایران است. با این سرور MCP، Claude و ChatGPT و دیگر دستیارها به همان پایگاه قوانین، آرا، نظریات مشورتی، بخشنامه‌ها و ماشین‌حساب‌های حقوقی چیستارا وصل می‌شوند و هر پاسخ پیوند منبع رسمی دارد.

Connect

Claude and ChatGPT (sign in, recommended)

  1. Add a custom connector with the URL https://hoghogh.ai/mcp/connect

    • Claude (claude.ai or the desktop app): Settings → Connectors → Add custom connector.

    • ChatGPT: Settings → Apps & Connectors → Create (developer mode).

  2. Your assistant opens Chistara's sign-in page: sign in to your Chistara account and choose Allow.

  3. Ask a question about Iranian law. The assistant calls the tools it needs and cites the sources.

This is standard OAuth 2.1 (PKCE, dynamic client registration). Disconnect at any time in Chistara: Settings → دستیار هوشمند → «برنامه‌های متصل».

Other MCP clients (Codex, Cursor, VS Code, Perplexity…)

Use your personal connection link from Settings → دستیار هوشمند → MCP (https://hoghogh.ai/mcp/<token>), or the server URL https://hoghogh.ai/mcp with the header Authorization: Bearer <token>.

A personal link is a key to your account. Paste it only into the assistant itself, never into a website that offers to connect it for you. You can revoke it and make a new one in the same settings card.

Tool listing is public so clients and directories can read the definitions; every tool call needs the personal link.

Sources

Statute text is kept verbatim from its official source and links the exact official page; rulings, advisory opinions and circulars come from the Judiciary's and government publications. Yearly figures (diyeh, minimum wage, court fees, tariffs) are read from the current year's official instruments. Calculators show the rule they applied and the article behind it.

Chistara is a legal research and drafting tool. For a decision in a real case, have a qualified lawyer review the result.
