Sk Eli MCP Server

sk-eli-mcp

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" }
  }
}

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.
