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, ...).
`tr_coverage()`	Declare what this connector covers, when each family was captured, and - explicitly - what it does NOT cover. Every gap carries a fallback.

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

Terminal

pip install -e ".[dev]"

config.json

{
  "mcpServers": {
    "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"
      }
    }
  }
}

Windows 11 with Smart App Control

Smart App Control blocks unsigned executables, which covers uvx.exe, pip.exe and the tr-eli-mcp.exe launcher that pip writes at install time. The python.exe and py.exe from the python.org installer are signed by the Python Software Foundation, so running the module through the interpreter works:

bash

python -m pip install tr-eli-mcp
python -m tr_eli_mcp

pip.exe is blocked for the same reason, so install with python -m pip, not pip install. If python is not on PATH, use the Windows launcher: py -3 -m tr_eli_mcp.

config.json

{ "mcpServers": { "tr-eli-mcp": { "command": "python", "args": ["-m", "tr_eli_mcp"] } } }

Do not turn Smart App Control off to work around this - it cannot be re-enabled without reinstalling Windows.

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).

Tests

bash

pytest tests/test_instructions_drift.py   # offline

Apache-2.0. The Turkish legislation served is official public data of the Republic of Turkey; this connector adds no rights over it.
