Hu Eli MCP server

hu-eli-mcp

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

An MCP server for Hungary's official national legislation database, the Nemzeti Jogszabalytar (NJT, njt.jog.gov.hu), maintained by MKIFK. It gives an AI agent a piece of Hungarian legislation resolved by its native ELI (European Legislation Identifier), with a verifiable citation: the ELI itself, a human-readable citation, and a link to the official source.

Part of the eu-legal-mcp line by MateMatic — one connector per EU member state, the same citation contract everywhere.

On ELI. Unlike the Netherlands and Sweden (earlier connectors in this line, neither of

which publishes native ELI), **Hungary has a genuine, documented national ELI

implementation since 2023 (njt.jog.gov.hu/eli/urisemak). eliuri is therefore the real

/eli/ URI the tool resolved — never a substitute identifier. See DISCOVERY.md.

Tools

Every response carries the citation contract:

"2013. évi V. törvény (a Polgári Törvénykönyvről)".

• eli_uri — the native ELI URI resolved, e.g. https://njt.jog.gov.hu/eli/TV/2013/5.
• humanreadablecitation — built from the parsed title + subtitle, e.g.

• source_url — the browsable njt.jog.gov.hu/jogszabaly/... document page.

No free-text search

NJT has no REST/JSON API and its search/browse UI is a JavaScript SPA requiring a session (not usable headlessly). Documents must be addressed by a known ELI — use hulistdoctypes / hulistissuers to discover valid codes, then hugetact / hugetlegislation. An unresolvable ELI (wrong year/serial/issuer, or wrong issuer-code case) surfaces as notfound — NJT itself redirects it to a search-assist page rather than a 404.

Install

pip install -e ".[dev]"

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

{
  "mcpServers": {
    "hu-eli-mcp": {
      "command": "hu-eli-mcp",
      "env": {
        "HU_ELI_BASE_URL": "https://njt.jog.gov.hu",
        "HU_ELI_CACHE_DIR": "~/.matematic/cache/hu-eli",
        "HU_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 hu-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:

python -m pip install hu-eli-mcp
python -m hu_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 huelimcp.

{ "mcpServers": { "hu-eli-mcp": { "command": "python", "args": ["-m", "hu_eli_mcp"] } } }

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