Install (one command)

Published on PyPI + MCP Registry (io.github.matematicsolutions/at-eli-mcp). Run without cloning:

uvx at-eli-mcp

Configure your MCP client (stdio):

{ "mcpServers": { "at-eli-mcp": { "command": "uvx", "args": ["at-eli-mcp"] } } }

Windows 11 with Smart App Control

Smart App Control blocks unsigned executables, which covers uvx.exe, pip.exe and the at-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 at-eli-mcp
python -m at_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 at_eli_mcp.

{ "mcpServers": { "at-eli-mcp": { "command": "python", "args": ["-m", "at_eli_mcp"] } } }

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

An MCP server for RIS (data.bka.gv.at), Austria's official legal information system (Rechtsinformationssystem des Bundes, operated by the Bundeskanzleramt). It searches and retrieves Austrian federal legislation (Bundesrecht) and case law (Judikatur) with verifiable ELI identifiers, native ECLI for decisions, and Austrian citations.

Part of the MateMatic eu-legal-mcp production line - the Austrian member, after the Polish sejm-eli-mcp and the German de-eli-mcp. Same architecture and citation contract, RIS source.

Scope. Covers Austrian federal law (Bundesrecht) and case law (Judikatur, with a native ECLI). State law (Landesrecht) is a later feature. Every response carries a dataset_note. Licence. Austrian Bundesgesetzblatt content and statutes are official works in the public domain; RIS is published as Open Government Data (keyless). This connector relays that public content with attribution and a source_url.

The tools

| Tool | What it does | |---|---| | at_search | Search federal law (GET /Bundesrecht) by free text and/or title. | | at_get_text | Fetch an act's full text (html or xml) from a hit's content URL. | | at_case_search | Search case law (GET /Judikatur) by free text, choosing a court (applikation). Hits carry a native ecli. | | at_get_case_text | Fetch a decision's full text from a case hit's content URL. | | at_list_collections | List the RIS collections and which are exposed. |

Every response carries the contract: eli_uri (a full ELI URL, e.g. https://www.ris.bka.gv.at/eli/bgbl/I/2026/6/20260218), human_readable_citation (e.g. Datenschutzgesetz, BGBl. I Nr. 165/1999), and source_url.

Install

cd at-eli-mcp
pip install -e .

Configure (Claude Code / any MCP client)

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

Environment:

• AT_ELI_BASE_URL - default https://data.bka.gv.at/ris/api/v2.6
• AT_ELI_CACHE_DIR - default ~/.matematic/cache/at-eli
• AT_ELI_AUDIT_DIR - default ~/.matematic/audit

No API key. RIS is keyless Open Government Data.

Governance

• Public data only - read-only against RIS; no client data leaves the machine beyond search parameters.
• Audit log - every tool call appends one JSON line to ~/.matematic/audit/at-eli-mcp.jsonl.
• Vendor-neutral - talks only to data.bka.gv.at and (for full text) ris.bka.gv.at; no LLM provider, no telemetry.
• Host-restricted text - full text is fetched only from ris.bka.gv.at.

See CONSTITUTION.md and DISCOVERY.md.
