Common questions

Is Hu Eli MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.3.3) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

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). eli_uri is therefore the real

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

Tools

Tool	What it does
`hu_get_act(year, serial)`	Metadata for a Hungarian Act (torveny) by ELI, e.g. year `2013`, serial `5` (the Civil Code). No issuer code needed.
`hu_get_legislation(doc_type, year, issuer, serial)`	Metadata for any other legislation (decrees etc.) by ELI — type, year, issuer (case-sensitive) and serial.
`hu_get_text(doc_type, year, serial, issuer=None)`	The full document HTML content for either an Act or other legislation.
`hu_list_doc_types()`	Valid NJT document-type codes (e.g. `TV`=Act, `R`=decree).
`hu_list_issuers()`	Valid NJT issuer codes (e.g. `Korm`=Government) — note the exact casing matters.
`hu_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 native ELI URI resolved, e.g. https://njt.jog.gov.hu/eli/TV/2013/5.
human_readable_citation — built from the parsed title + subtitle, e.g. *"2013. évi V. törvény (a Polgári Törvénykönyvről)"*.
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 hu_list_doc_types / hu_list_issuers to discover valid codes, then hu_get_act / hu_get_legislation. An unresolvable ELI (wrong year/serial/issuer, or wrong issuer-code case) surfaces as not_found — NJT itself redirects it to a search-assist page rather than a 404.

Install

As a Claude plugin (Claude Code or the desktop app, needs uv); see plugin/README.md for what it sends and stores:

/plugin marketplace add matematicsolutions/hu-eli-mcp

/plugin install hu-eli-mcp@hu-eli-mcp

pip install -e ".[dev]"

"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 hu_eli_mcp.

{ "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.

Design

Public data only. Read-only against the keyless, official njt.jog.gov.hu; nothing is sent beyond the ELI path being resolved. Honors robots.txt (never calls /search/*).
Audit log. Every call appends one JSON line to ~/.matematic/audit/hu-eli-mcp.jsonl (record-keeping).
Network - the server talks to the official source(s) named above and the local filesystem. Once, on first use, it also fetches a small configuration file (hu-runtime.json.gz, updated source addresses) from this repository's GitHub Releases. That request carries no query content; GitHub's download counter for the file is the only usage signal we see. HU_ELI_RUNTIME_URL="" turns it off; the Claude plugin ships with it off. No LLM provider, no other telemetry. Own backoff + on-disk cache.
No fabrication. The ELI, title and citation are parsed from the resolved document page. If NJT's markup 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, including the njt.hu → njt.jog.gov.hu domain discovery and the issuer-code casing gotcha).

Tests

Licence

Apache-2.0. The Hungarian legislation served is official public data of Hungary; this connector adds no rights over it.
