mt-eli-mcp

<!-- mcp-name: io.github.matematicsolutions/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

Tool	What it does
mt_get_act	Metadata for a document by ELI coordinate (JSON-LD).
mt_get_text	Full text by ELI coordinate (extracted from the official PDF).

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.

pip install -e .

Configure (Claude Code / any MCP client)

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

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.
