tr-eli-mcp

<!-- mcp-name: io.github.matematicsolutions/tr-eli-mcp -->

An MCP server for Turkish legislation (Kanun/laws, KHK/decree-laws, Tuzuk/statutes, Yonetmelik/regulations, Cumhurbaskanligi Kararnamesi/presidential decrees, Teblig/communiques and more), served as a keyless JSON API by the Adalet Bakanligi (Ministry of Justice) at bedesten.adalet.gov.tr/mevzuat. It gives an AI agent legislation text and metadata with a verifiable citation: a resolvable identifier, a human-readable citation, and a link to the official source.

Part of the eu-legal-mcp line by MateMatic — one connector per country, the same citation contract everywhere. Turkey is included under this line's broader "Europe" framing (Council of Europe member, EU accession candidate), alongside connectors that map strictly to EU-27 membership.

On ELI. Turkey does not publish native ELI (/eli/) URIs. To keep the line's contract honest, eli_uri carries the canonical, resolvable mevzuat.gov.tr URL instead — e.g. https://www.mevzuat.gov.tr/mevzuat?MevzuatNo=5237&MevzuatTur=1&MevzuatTertip=5 — which every Bedesten search record already supplies. The connector never fabricates an /eli/ URI and says so in its tool instructions. See DISCOVERY.md.

On case law. This connector covers legislation only. Yargitay (Court of Cassation) decision search was unreachable (TCP timeout) from the build network, and Anayasa Mahkemesi (Constitutional Court) exposes only a client-rendered SPA with no discovered server API. Neither is wired up here — see DISCOVERY.md for what was actually checked.

Tools

Tool	What it does
tr_search_legislation(query, mevzuat_turu=None, mevzuat_no=None, baslikta_ara=True)	Search Turkish legislation by title and/or full text, optionally filtered by type and number.
tr_get_legislation_content(mevzuat_id)	The full text of one document (HTML converted to plain text).
tr_get_legislation_toc(mevzuat_id)	The article tree (madde agaci / table of contents) of one document.
tr_list_legislation_types()	Enumerate all legislation types with live document counts (KANUN, KHK, YONETMELIK, ...).

Every response carries the citation contract:

• eli_uri — the canonical, resolvable mevzuat.gov.tr identifier (see the ELI note above).
• human_readable_citation — the Turkish citation convention: law number + name + Official Gazette (Resmi Gazete) date/number, e.g. 5237 sayili Turk Ceza Kanunu (Resmi Gazete: 12/10/2004, Sayi: 25611).
• source_url — the same canonical mevzuat.gov.tr page.

Install

pip install -e ".[dev]"

Register it with your MCP client (see .mcp.json.example):

    "tr-eli-mcp": {
      "command": "tr-eli-mcp",
      "env": {
        "TR_ELI_BASE_URL": "https://bedesten.adalet.gov.tr/mevzuat",
        "TR_ELI_CACHE_DIR": "~/.matematic/cache/tr-eli",
        "TR_ELI_AUDIT_DIR": "~/.matematic/audit"
      }
    }
  }
}

Design

• Public data only. Read-only against the keyless Adalet Bakanligi Bedesten API; nothing is sent beyond the query / document id.
• Audit log. Every call appends one JSON line to ~/.matematic/audit/tr-eli-mcp.jsonl (AI Act art. 12 record-keeping).
• Vendor-neutral. No LLM provider, no telemetry; own backoff + on-disk cache.
• No fabrication. Identifiers and titles are parsed from the source record. If Bedesten's schema changes, the connector fails loudly rather than returning stale or invented data.

See CONSTITUTION.md (the 4 principles) and DISCOVERY.md (how the source was mapped, and what was ruled out).
