found,kind, and arecordin the matching search tool's shape, withalternatives_countwhen several documents matched. A miss returnsfound: falsewithguidanceinstead of an error - A norm resolves to the cited law:
- the law is matched as RIS files it ("§ 2 EStG" → EStG 1988 § 2; "AlVG 1977" → the AlVG, filed without its year; "VwGVG 2014 §28" → VwGVG § 28), and a long title is read by its short form ("StaatsanwaltschaftsG - StAG §35" → StAG § 35)
- sub-provisions and a trailing ";" are set aside ("Art. 6 (1) B-VG" → B-VG Art 6), and an ordinal-led abbreviation reads like any other ("1. COVID-19-JuBG §1")
- a cited version is set aside ("ABGB idF BGBl I 2010/28 §988" → ABGB § 988 as in force on the requested date, never the amending act's gazette entry), with a note saying the cited version was not applied
- an entry citing several provisions ("DSG §1, §24", "ZPO §179. ZPO §275 Abs2") resolves the first and names the rest
- An EU act RIS does not consolidate ("DSGVO Art32", "RL 2006/123/EG", "VO (EG) 178/2002 Art3") returns
found: falsewith its EUR-Lex link, without a RIS request - A gazette number without its part ("BGBl. Nr. 50/2025") comes back ambiguous, naming parts I, II, and III
- A string of several gazette cites, as a consolidated record's
promulgationjoins them ("BGBl. Nr. 267/1967 zuletzt geändert durch BGBl. I Nr. 17/2026"), resolves by its first cite and names the others; a first cite in a gazette the lookup does not read returnsfound: falsewithout a search. A state organ carrying its Bundesland ("LGBlNÖ Nr. 72/2016") needs nostatehint, and a disagreeing hint is reported as not applied - An RIS ELI link (a consolidated-law or authentic-gazette record's
eliordocument_url, overhttpsorhttp, with or without the scheme) resolves to the provision or entry it names, whatever version is in force;in_force_as_ofandstatedon't apply. A path that spells a gazette cite (/eli/bgbl/{I|II|III}/{year}/{number},/eli/lgbl/{state}/{year}/{number}, or/eli/{bgbl|rgbl|stgbl|gbloe}/{year}/{number}with no part, as before 1997) followed by nothing but date, language, or format segments resolves as that cite (/eli/bgbl/II/2026/317,/eli/bgbl/1974/60). Other/eli/layouts, including a provision's path cut before its document number (/eli/bgbl/i/1999/165/A2P4), returnfound: false,kind: unknown, without a request - A Rechtssatz number ("RS0022961", "RIS-Justiz RS0022961 [T3]", "RW0001127") resolves to that headnote through Justiz whatever the
courthint; a bracketed T number is not searched - A VwSlg cite VwGH stores in another shape ("VwSlg 0017 F/1947", "VwSlg. 1485 A/1950", "VwSlg 1809/50") resolves through one more search within the cited year
ris_get_document tool
- Address by
document_number+application, or by adocument_url: a record's owndocument_urloreli(an ELI orDokument.wxeweb view, read for the document it names), acontent_urlsentry, or a draft'smaterials[].url;formatismarkdown(default),html,xml, orurls_only - Every result carries
binding_statusandauthentic_pdf_urlwhere one exists. Where a PDF is the only rendition (district and municipal promulgations, court rules, party-transparency decisions, council minutes, and draft companions filed without HTML),markdownreturns the text extracted from it: plain text with a--- Page N of M ---line before each page,text_source: pdf, and a notice naming the PDF. A scanned PDF with no text layer, one over 16 MiB, or one that cannot be fetched in time returns a notice with the usable URL instead of failing, as dohtmlandxmlthere and the 1848–1940 gazettes, which have no PDF to read - Markdown writes image references as absolute URLs on the content host. A rendition that is nothing but page images reads its PDF's text, and keeps the image URLs with a notice when the PDF has none
- Markdown over 40,000 bytes returns
kind: outline; re-call withsectionsto fetch entries.htmlandxmlover 40,000 bytes returnkind: linkwithbyte_sizeandcontent_urls, so read withmarkdown
ris_track_changes tool
application(any of the 39 codes) pluschanged_from/changed_to;include_deletedadds removals, which no other tool reports- Records carry
changed,published, andbinding_status; deletions setdeleted: truewithdeleted_at - Law rows carry
section_label,law_id, andin_force_from/in_force_until(no end date is not the same as in force now), and decision rows carrycase_numbersanddecision_date
ris_list_reference tool
topicselects one of 17 static tables: applications, courts, states, decision types and kinds, issuing bodies, ministries, collections, stages, changed-since intervals, section types, gazette parts, law types, district authorities, justiz subject areas, search syntax, and citation formats- Returns
summaryandentries(value,label,details) with no upstream call
ris://document/{application}/{documentNumber} resource
text/markdownof one document, addressed byapplication+documentNumberfrom a search or lookup result; same content asris_get_documentwithformat: markdown- Applications that publish only a PDF return its extracted text in a fenced block with a note naming the PDF; the 1848–1940 gazettes and a PDF with no extractable text return a note pointing at the PDF or scan. Oversized text returns the outline, so use the tool to fetch an entry
Features
Built on @cyanheads/mcp-ts-core: stdio and Streamable HTTP transports, pluggable auth (none / jwt / oauth), swappable storage (in-memory, filesystem, Supabase, Cloudflare KV/R2/D1), structured logging with optional OpenTelemetry tracing.
RIS-specific:
- All 39 OGD applications: consolidated law, federal, state, district, and municipal gazettes, 17 court and tribunal collections, the lawmaking pipeline, and sectoral announcements
- Citations resolve through exact filters (section plus title, gazette number, Geschäftszahl, Sammlungsnummer) rather than keyword search
- Dates are
YYYY-MM-DD; search tools page withpageandpage_size(1–100, served as pages of 10 or 20; default 20); omit a text filter rather than sending it blank - Court, application, state, and ministry codes come from
ris_list_reference - Tool descriptions are English; titles, field values, and RIS error messages stay German
Agent-friendly output:
- Every record carries a typed binding status (
authentic,consolidated_informational,historical_record,decision,preparatory,administrative_directive,translation) - Paged results report
totalCountandtruncatedand echo what the server applied, such asappliedInForceAsOfandservedApplication - Typed error reasons (
court_filter_mismatch,cross_tier_range,invalid_query,document_not_found, …) and zero-hit notices name the next call
Getting started

Running the server
Local development
Requires Bun v1.4.4 or higher (or Node.js v24+).

Clone and install:
git clone https://github.com/cyanheads/ris-austria-mcp-server.git cd ris-austria-mcp-server && bun install -
Build and run:
# One-time build bun run rebuild # Run the built server bun run start:stdio # or bun run start:http -
Run checks and tests:
bun run devcheck # Lint, format, typecheck, security bun run test # Vitest test suite bun run lint:mcp # Validate MCP definitions against spec
Docker
docker run --rm -p 3010:3010 ghcr.io/cyanheads/ris-austria-mcp-server:latest
The image defaults to HTTP transport, stateless session mode, and logs to /var/log/ris-austria-mcp-server. To run it over stdio from an MCP client, use "command": "docker" with "args": ["run", "-i", "--rm", "-e", "MCP_TRANSPORT_TYPE=stdio", "ghcr.io/cyanheads/ris-austria-mcp-server:latest"]. To build locally, docker build -t ris-austria-mcp-server .; OpenTelemetry peer dependencies are installed by default — build with --build-arg OTEL_ENABLED=false to omit them.

Development guide
See CLAUDE.md / AGENTS.md for development guidelines and architectural rules. The short version:
- Handlers throw, framework catches — no
try/catchin tool logic - Use
ctx.logfor request-scoped logging,ctx.statefor tenant-scoped storage - Register new tools and resources via
createApp()insrc/index.ts - Wrap the RIS API: validate raw → normalize to domain type → return output schema; never fabricate missing fields
