mt-eli-mcp

An MCP server for the Maltese legislation portal legislation.mt, the official source of consolidated Maltese law. It fetches document metadata and full text, 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, LT, SK and RO. Same citation contract, legislation.mt source. Malta is ELI-native; each page carries schema.org/ELI JSON-LD.

Scope. This MVP fetches a document's metadata (from JSON-LD) and full text by ELI coordinate (chapters, the Constitution, subsidiary legislation, Acts, Legal Notices). There is no free-text search; address documents by their ELI coordinate. Languages: English (eng) and Maltese (mlt). Every response carries a dataset_note.

Text comes from PDF. Malta publishes the consolidated text only as PDF. mt_get_text downloads the official PDF and extracts the text with pypdf; layout-dependent artefacts are possible. Every text response carries a text_note.

The tools

ELI coordinates (eli): cap/586 (Chapter), const (Constitution), sl/586.01 (subsidiary legislation), act/2018/20 (Act), ln/2018/123 (Legal Notice).

Every response carries the contract: eli_uri (the legislation.mt URL, e.g. https://legislation.mt/eli/cap/586/eng), human_readable_citation (e.g. Data Protection Act (Cap. 586)), and source_url.

Install

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

uvx mt-eli-mcp

Or from source:

cd mt-eli-mcp
pip install -e .

Configure (Claude Code / any MCP client)

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

Windows 11 with Smart App Control

Smart App Control blocks unsigned executables, which covers uvx.exe, pip.exe and the mt-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 mt-eli-mcp
python -m mt_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 mt_eli_mcp.

{ "mcpServers": { "mt-eli-mcp": { "command": "python", "args": ["-m", "mt_eli_mcp"] } } }

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

Environment:

• MT_ELI_BASE_URL - default https://legislation.mt
• MT_ELI_CACHE_DIR - default ~/.matematic/cache/mt-eli
• MT_ELI_AUDIT_DIR - default ~/.matematic/audit

No API key. legislation.mt is open data.

Governance

• Public data only - read-only against legislation.mt; no client data leaves the machine.
• Audit log - every tool call appends one JSON line to ~/.matematic/audit/mt-eli-mcp.jsonl.
• Vendor-neutral - talks only to legislation.mt; 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 live legislation.mt
