Common questions

Is Cz 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 (0.2.3) 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.

cz-eli-mcp

An MCP server for the Czech e-Sbirka legal database (e-sbirka.gov.cz), the official Collection of Laws (Sbirka zakonu), via its open-data SPARQL endpoint. It searches acts and fetches their full consolidated text, with verifiable citations.

Part of the MateMatic eu-legal-mcp production line - after PL, DE, AT, ES, FI, IE, NL, SE, FR, LU and DK. Same citation contract, e-Sbirka source. This is the first connector in the line that talks SPARQL/RDF rather than a REST/XML API.

Scope. This MVP searches acts (by year and/or a citation substring), returns metadata, and

assembles the full consolidated text of the latest version. ~92,000 acts, updated daily,

licensed CC BY 4.0. Language: Czech. Every response carries a dataset_note.

ELI is national, not data.europa.eu. The act IRI follows the ELI URI template

(eli/cz/sb/{year}/{number}) but is minted by the e-Sbirka open-data graph

(opendata.eselpoint.gov.cz), not resolvable on data.europa.eu. The readable page is on

e-sbirka.gov.cz. Every response carries an eli_note saying so.

Text is assembled, not a single file. e-Sbirka exposes the consolidated text as ordered

HTML fragments over SPARQL; cz_get_text reconstructs the plain text from them. There is no

single official XML/PDF manifestation.

The tools

Tool	What it does
`cz_search`	Find acts by year and/or a citation substring (discovery).
`cz_get_act`	Metadata for an act by year + number, plus the latest consolidated version date.
`cz_get_text`	Full consolidated text of an act, assembled from the latest version's fragments.
`cz_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 contract: eli_uri (the national ELI IRI, e.g. https://opendata.eselpoint.gov.cz/esel-esb/eli/cz/sb/2019/110), human_readable_citation (e.g. 110/2019 Sb.), and source_url (the e-sbirka.gov.cz page).

Install

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

uvx cz-eli-mcp

Or from source:

cd cz-eli-mcp

pip install -e .

Configure (Claude Code / any MCP client)

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

Windows 11 with Smart App Control

Smart App Control blocks unsigned executables, which covers uvx.exe, pip.exe and the cz-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 cz-eli-mcp

python -m cz_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 cz_eli_mcp.

{ "mcpServers": { "cz-eli-mcp": { "command": "python", "args": ["-m", "cz_eli_mcp"] } } }

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

Environment:

CZ_ELI_ENDPOINT - default https://opendata.eselpoint.gov.cz/sparql
CZ_ELI_CACHE_DIR - default ~/.matematic/cache/cz-eli
CZ_ELI_AUDIT_DIR - default ~/.matematic/audit

No API key. The e-Sbirka open-data SPARQL endpoint is keyless.

Governance

Public data only - read-only SPARQL against e-Sbirka; no client data leaves the machine.
Audit log - every tool call appends one JSON line to ~/.matematic/audit/cz-eli-mcp.jsonl.
Vendor-neutral - talks only to opendata.eselpoint.gov.cz; no LLM provider, no telemetry.
Verifiable citations - every response is independently checkable via source_url.

See CONSTITUTION.md and DISCOVERY.md.

Tests

pip install -e ".[dev]"

pytest tests/test_instructions_drift.py tests/test_parse.py -v # offline pytest tests/test_smoke.py -v # hits the live SPARQL endpoint
