at-ris-mcp

A generic MCP server and standalone Python client library for the
Austrian RIS (Rechtsinformationssystem des Bundes), the official legal
information system of the Republic of Austria, operated by the Bundeskanzleramt.
It covers federal law (Bundesrecht — including consolidated law BrKons,
the official gazettes, drafts and government bills), state law (Landesrecht
of the nine Bundesländer), case law (Judikatur — OGH, VfGH, VwGH, BVwG,
LVwG and more), ministerial decrees, district and municipal law, plus a
change-monitoring feed — via the keyless OGD API at
https://data.bka.gv.at/ris/api/v2.6/.
Why this exists
Compared with existing RIS tooling, at-ris-mcp adds:
- Consolidated law (
BrKons) — the currently applicable text, not just the
gazette novellas.
- Section-precise access — retrieve a single
§/Artikel/Anlage
(Abschnitt.*).
- Historical version — the law as it stood on a given date
(
Fassung.FassungVom).
- Clean Markdown — RIS HTML (≈40 KB of CSS boilerplate per document) is
stripped to the legal text, with a
raw switch for the untouched original.
Two packages, one repo
ris_client — a standalone, MCP-independent library. Import it directly.
ris_mcp — a thin FastMCP/stdio wrapper exposing 10 tools. Contains no
logic of its own.
Install
pip install at-ris-mcp
pip install "at-ris-mcp[mcp]"
Run the MCP server (stdio)
at-ris-mcp
python -m ris_mcp
Remote transport (HTTP / SSE)
For hosted or remote deployments the server can also speak streamable HTTP or
SSE instead of stdio:
at-ris-mcp --transport http --host 0.0.0.0 --port 8000
at-ris-mcp --transport sse --port 9000
RIS_MCP_TRANSPORT=http RIS_MCP_PORT=8000 at-ris-mcp
The HTTP endpoint is served at /mcp by default (override with --path /
RIS_MCP_PATH). stdio remains the default when no transport is given.
| Tool | Purpose |
|---|
ris_search_law | Search Bundesrecht (default BrKons; also BgblAuth, Begut, RegV, …). Section + Fassung filters. |
ris_get_law_text | Full text of a statute/section (markdown | html | xml | raw). |
ris_search_case | Search Judikatur (default Justiz; all courts). Filter by applied norm. |
ris_get_case_text | Full text of a decision. |
ris_search_state_law | Search Landesrecht (9 Bundesländer; default LrKons). Select states via bundeslaender. |
ris_search_misc | Search Sonstige (ministerial decrees Erlaesse, Avsv, …). |
ris_search_district | Search district authority notices (Bezirke / Bvb). |
ris_search_municipality | Search municipal law (Gemeinden / Gemeinderecht Gr/GrA). |
ris_list_collections | Which endpoints/applications are covered. |
ris_list_changes | Change/early-warning feed (RIS History) via the OGD SOAP endpoint, incl. deleted documents. |
Library usage
import asyncio
from ris_client import RisClient, LawSearchRequest, TextFormat
async def main():
async with RisClient() as c:
res = await c.search_law(LawSearchRequest(suchworte="Datenschutzgesetz",
page_size="Ten"))
hit = res.items[0]
print(hit.human_readable_citation, hit.eli_uri)
text = await c.get_text(hit.content_urls["html"], TextFormat.markdown)
print(text.content[:500])
asyncio.run(main())
Configuration (environment variables)
| Variable | Default | Meaning |
|---|
RIS_BASE_URL | https://data.bka.gv.at/ris/api/v2.6 | API base (version isolation). |
RIS_SOAP_URL | https://data.bka.gv.at/ris/ogd/v2.6/ | OGD SOAP endpoint (used by ris_list_changes). |
RIS_USER_AGENT | at-ris-mcp/<version> (+…) | Descriptive UA (netiquette). |
RIS_RATE_MS | 1200 | Minimum delay between requests (ms). |
RIS_TIMEOUT_S | 30 | HTTP timeout. |
RIS_MAX_RETRIES | 3 | Retries on 429/5xx (incl. 503). |
RIS_CACHE_DIR | ~/.cache/at-ris-mcp | SQLite cache location. |
RIS_CACHE_ENABLED | true | Toggle the cache. |
RIS_AUDIT_DIR | (unset) | If set, append a JSONL audit line per call (no full text, no client data). |
RIS_MCP_TRANSPORT | stdio | Server transport: stdio | http | sse | streamable-http. |
RIS_MCP_HOST | 127.0.0.1 | Bind host for http/sse. |
RIS_MCP_PORT | 8000 | Bind port for http/sse. |
RIS_MCP_PATH | (transport default) | URL path for the HTTP endpoint. |
Netiquette & rate limiting
Per the RIS OGD FAQ: a 1–2 s pause per page is enforced by the client; bulk
access should occur outside office hours (18:00–06:00) or on weekends and be
announced to ris.it@bka.gv.at. A descriptive User-Agent is sent by default.

No legal advice. Only the authentic promulgation text

Consolidated law and all other documents are for information only. Every

Scope (v1.0)
Covered: Bundesrecht (BrKons, BgblAuth, BgblPdf, BgblAlt, Begut,
RegV, Erv — English translations), Judikatur (all courts), the History
change-feed (ris_list_changes, incl. deleted documents), Landesrecht
(9 Bundesländer: LrKons, LgblAuth, Lgbl, LgblNO, Vbl), Sonstige
(Erlaesse, Avsv, Avn, Spg, KmGer, Upts, Mrp, PruefGewO — with
app-specific fine filters), Bezirke (Bvb) and Gemeinden (Gr, GrA).
English translations (Erv): search via ris_search_law with
applikation="Erv". suchworte/titel map to the RIS SearchTerms/Title
parameters automatically.
State-law note: for consolidated state law (LrKons), select the states
via bundeslaender (e.g. ["Kaernten","Tirol"]); this maps to the dotted
Bundesland.SucheIn<Land>=true flags the API requires (the flat form is
silently ignored for LrKons).
History note: consolidated federal law is monitored under the application
name Bundesnormen (not BrKons), consolidated state law under
Landesnormen. The History query uses the OGD SOAP endpoint, since it is
not exposed via the REST GET API.
Development
pip install -e ".[dev,mcp]"

Release
Releases are automated. Pushing a version tag (vX.Y.Z) triggers GitHub
Actions to build the distributions, publish to PyPI (via Trusted
Publishing / OIDC — no API token), create a GitHub Release, and register
the new version in the MCP Registry.
git tag -a vX.Y.Z -m "vX.Y.Z"
git push origin vX.Y.Z
To build locally without publishing:
python -m build
python -m twine check dist/*
The MCP-registry entry is described by server.json
(name io.github.paragraflabs/at-ris-mcp); the matching mcp-name: marker is
embedded near the top of this README.
