Slovak Legislation

An MCP server for the Slovak Collection of Laws (Zbierka zákonov) via static.slov-lex.sk, the JavaScript-free static mirror of the Slov-lex portal. It fetches Slovak legislation and its consolidated versions, with verifiable citations.

Part of the MateMatic eu-legal-mcp production line - after PL, DE, AT, ES, FI, IE, NL, SE, FR, LU, DK, CZ, HR and LT. Same citation contract, Slov-lex source. Slovakia implements ELI (Pillar I).

Scope. This MVP lists an act's consolidated versions, returns metadata, and fetches the full text of a version. Acts are addressed by year + number; the portal is path-based, not keyword search. Coverage 1918-present. Language: Slovak. Every response carries a dataset_note.

ELI is national (Pillar I), not data.europa.eu. The static pages carry no machine-readable ELI metadata, so eli_uri is the canonical Slov-lex URL (slov-lex.sk/pravne-predpisy/SK/ZZ/{year}/{number}), the stable national identifier. Full text is served from the static.slov-lex.sk mirror (source_url). Every response carries an eli_note.

Text is extracted from the official HTML. Slov-lex serves the consolidated text as HTML; sk_get_text extracts the plain text from the act container.

The tools

Every response carries the contract: eli_uri (the Slov-lex URL, e.g. https://www.slov-lex.sk/pravne-predpisy/SK/ZZ/2018/18/), human_readable_citation (e.g. č. 18/2018 Z. z.), and source_url.

Install

Run it with no install step (once published to PyPI):

uvx sk-eli-mcp

Or from source:

cd sk-eli-mcp
pip install -e .

Configure (Claude Code / any MCP client)

{
  "mcpServers": {
    "sk-eli-mcp": { "command": "sk-eli-mcp" }
  }
}

Windows 11 with Smart App Control

Smart App Control blocks unsigned executables, which covers uvx.exe, pip.exe and the sk-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 sk-eli-mcp
python -m sk_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 sk_eli_mcp.

{ "mcpServers": { "sk-eli-mcp": { "command": "python", "args": ["-m", "sk_eli_mcp"] } } }

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

Environment:

• SK_ELI_BASE_URL - default https://static.slov-lex.sk
• SK_ELI_CACHE_DIR - default ~/.matematic/cache/sk-eli
• SK_ELI_AUDIT_DIR - default ~/.matematic/audit

No API key. The Slov-lex static mirror is keyless.

Governance

• Public data only - read-only against Slov-lex; no client data leaves the machine.
• Audit log - every tool call appends one JSON line to ~/.matematic/audit/sk-eli-mcp.jsonl.
• Vendor-neutral - talks only to static.slov-lex.sk; no LLM provider, no telemetry.
• Verifiable citations - every response is independently checkable via source_url.

See CONSTITUTION.md and DISCOVERY.md.
