It searches Lithuanian legislation by title and fetches full text, with verifiable citations.\n\nPart of the MateMatic `eu-legal-mcp` production line - after PL, DE, AT, ES, FI, IE, NL, SE, FR,\nLU, DK, CZ and HR. Same citation contract, TAR source. This connector reads a REST-JSON open-data\nAPI (the data.gov.lt Spinta endpoint).\n\n> **Scope.** This MVP searches acts by title substring, returns metadata, and fetches the full\n> Lithuanian text. ~CC BY 4.0 open data; acts are addressed by their TAR code (`tar_kodas`).\n> Language: Lithuanian. Every response carries a `dataset_note`.\n>\n> **ELI is national, not data.europa.eu.** Lithuania has no `data.europa.eu` ELI for the TAR\n> dataset. `eli_uri` carries the canonical `e-tar.lt` legalAct URL (the stable national\n> identifier), which is also the `source_url`. Every response carries an `eli_note` saying so.\n\n## The tools\n\n| Tool | What it does |\n|---|---|\n| `lt_search` | Find acts whose title contains a substring (optionally by type). |\n| `lt_get_act` | Metadata for an act by its TAR code. |\n| `lt_get_text` | Full Lithuanian text of an act by its TAR code. |\n| `lt_coverage` | Declare what this connector covers, when each family was captured, and - explicitly - what it does NOT cover. Every gap carries a fallback. |\n\nEvery response carries the contract: `eli_uri` (the `e-tar.lt` URL, e.g.\n`https://e-tar.lt/portal/lt/legalAct/...`), `human_readable_citation` (title + official number),\nand `source_url`.\n\n## Install\n\nRun it with no install step (once published to PyPI):\n\n```bash\nuvx lt-eli-mcp\n```\n\nOr from source:\n\n```bash\ncd lt-eli-mcp\npip install -e .\n```\n\n## Configure (Claude Code / any MCP client)\n\n```json\n{\n  \"mcpServers\": {\n    \"lt-eli-mcp\": { \"command\": \"lt-eli-mcp\" }\n  }\n}\n```\n\n### Windows 11 with Smart App Control\n\nSmart App Control blocks unsigned executables, which covers `uvx.exe`, `pip.exe`\nand the `lt-eli-mcp.exe` launcher that pip writes at install time. The `python.exe` and\n`py.exe` from the python.org installer are signed by the Python Software\nFoundation, so running the module through the interpreter works:\n\n```bash\npython -m pip install lt-eli-mcp\npython -m lt_eli_mcp\n```\n\n`pip.exe` is blocked for the same reason, so install with `python -m pip`, not\n`pip install`. If `python` is not on PATH, use the Windows launcher: `py -3 -m lt_eli_mcp`.\n\n```json\n{ \"mcpServers\": { \"lt-eli-mcp\": { \"command\": \"python\", \"args\": [\"-m\", \"lt_eli_mcp\"] } } }\n```\n\nDo not turn Smart App Control off to work around this - it cannot be re-enabled\nwithout reinstalling Windows.\n\nEnvironment:\n\n- `LT_ELI_BASE_URL` - default `https://get.data.gov.lt`\n- `LT_ELI_CACHE_DIR` - default `~/.matematic/cache/lt-eli`\n- `LT_ELI_AUDIT_DIR` - default `~/.matematic/audit`\n\nNo API key. The data.gov.lt open-data API is keyless.\n\n## Governance\n\n- **Public data only** - read-only against data.gov.lt; no client data leaves the machine.\n- **Audit log** - every tool call appends one JSON line to `~/.matematic/audit/lt-eli-mcp.jsonl`.\n- **Vendor-neutral** - talks only to `get.data.gov.lt`; no LLM provider, no telemetry.\n- **Verifiable citations** - every response is independently checkable via `source_url`.\n\nSee `CONSTITUTION.md` and `DISCOVERY.md`.\n\n## Tests\n\n```bash\npip install -e \".[dev]\"\npytest tests/test_instructions_drift.py tests/test_parse.py -v   # offline\npytest tests/test_smoke.py -v                                    # hits live data.gov.lt\n```\n\n## Licence\n\nApache-2.0. © Matematic Solutions / Wieslaw Mazur.
