Details
From the project READMEagentic-firmenbuch
Austria's entire company register, queryable by AI agents in plain language. Official master data, annual accounts and key ratios for every firm – served over MCP, answered on real numbers instead of hallucinations.
Try the playground · Start free: 50 credits, 7 days · Quickstart ↓
A live, automated data product over the Austrian Firmenbuch (free EU HVD / High Value Datasets), served through a multi-tenant MCP server. A deterministic Azure pipeline pulls the published Jahresabschluss (annual financial statement) filings from the official register, parses them, consolidates per company, computes ratios/growth/trends, and serves the result to MCP clients. The whole register holds ~640k legal entities; the served slice is currently ~341k and grows as the backfill progresses. Version 1 = facts + clean derivations only (no scoring, no third-party enrichment, no NACE, no AI summaries).
Also available: Germany and the wider DACH region. Alongside this Austrian product, a unified
agentic-registerendpoint serves both the Austrian Firmenbuch and the German Handelsregister / Unternehmensregister over a single MCP. It is listed in the official MCP registry asio.github.jkbngb/handelsregister(spec:handelsregister.server.json) and reachable athttps://register.agentic-firmenbuch.at/mcpwith the same account and the same access rules (free trial, then Pro). A search returns matches from both countries, tagged bycountry(AT/DE).
Quickstart
Use the hosted service – query official Firmenbuch data from an MCP client that accepts an HTTP header key (Claude Code, VS Code with GitHub Copilot, Cursor, …):
- Get an API key at agentic-firmenbuch.at. Every new account starts with 50 free credits, valid for 7 days (1 credit per company, so about 50 companies), one allowance shared by the web console and Claude. After the trial, access from Claude, Cursor or any MCP/API client needs Pro at €79/month plus VAT: unlimited queries within fair-use limits (10,000 calls per day, 20,000 export rows and 50 documents per month), cancel monthly. Credit packs are a web-console product and do not unlock MCP/API access. (Connecting via a sandboxed client like Claude Cowork/claude.ai grants the 50 credits on first connect, no key needed, see below.)
- Add the server. Claude Code (terminal), one line:
GitHub Copilot / VS Code:claude mcp add --scope user --transport http agentic-firmenbuch https://mcp.agentic-firmenbuch.at/mcp --header "X-API-Key: <your-key>"code --add-mcp "{\"name\":\"agentic-firmenbuch\",\"type\":\"http\",\"url\":\"https://mcp.agentic-firmenbuch.at/mcp\",\"headers\":{\"X-API-Key\":\"<your-key>\"}}". Any other HTTP-MCP-Header client: URLhttps://mcp.agentic-firmenbuch.at/mcp, headerX-API-Key: <your-key>. - Ask in natural language, e.g. "Aktive GmbHs in Oberösterreich mit Bilanzsumme über 5 Mio. €, sortiert nach Umsatz." The agent calls
search_companies/get_company_detailsand answers with official data – no SDK required.
Claude Cowork & claude.ai (sandboxed clients) don't take the API-key header – they connect via
Settings → Connectors → Add custom connectorwith the URLhttps://mcp.agentic-firmenbuch.at/mcpand a one-time email login (OAuth, no key). Step-by-step with screenshots: agentic-firmenbuch.at/cowork.html.

All tools return a processed derivative of official Austrian Firmenbuch data (source: BMJ – Justiz, CC BY 4.0). Concretely: we ingest the published filings from the register, parse and consolidate them, compute ratios, and serve that from our own database — no web scraping, no LLM-generated summaries, no third-party data mixed in (V1). Every response carries provenance.data_version + built_at and names the original source, so the agent can attribute it correctly; for the authoritative record, the official Firmenbuch always governs.
Currently served: ~341,000 active legal entities across all Rechtsformen (GmbH, AG, KG, OG, EU, Genossenschaft, Privatstiftung, SE …). The full register has ~640,000 entities; the gap is companies without a published Jahresabschluss plus inactive/deleted entries, which are added step by step.

Monorepo layout (agentic-first)
This repository is the agentic-first monorepo umbrella. It separates source-agnostic
shared code from per-source products, so another source-specific product can be added without
touching the Austrian pipeline:
agentic-first/ (this repo)
├── packages/ SHARED — source-agnostic, zero Firmenbuch/UGB knowledge
│ ├── core/ (fbl_core) lineage/meta + metric contracts, config, storage clients
│ └── auth/ (fbl_auth) signup, token issue/validate, metering, 00_accounts
└── products/
└── agentic-firmenbuch/ AUSTRIA product (live) — README below
├── packages/
│ ├── core_at/ (fbl_core_at) UGB taxonomy, Firmenbuch domain models, ÖNACE, FI dirs

│ │ 50_consolidate, 30_derive, 10_present, mcp_server, orchestration
│ └── …
└── tests/ AT integration tests + golden fixtures
Additional source-specific products are added in their own separate repositories that consume
packages/{core,auth} as a dependency (they are not scaffolded here). The precise
1:1 / adapt / product-local reuse boundary is the reuse table (Appendix R) of the technical spec, and the generic recipe is in
docs/monorepo/ADDING_A_PRODUCT.md.

Pipeline (numbered layers, 90 → 10)

(Cosmos) (Cosmos) (Cosmos)
side: 00_accounts (MCP signup) · 00_directories (register-based FI flag, OeNB) reserved for v2: 40_enriched, 20_scored
90_raw is the immutable source of truth (every downloaded XML/PDF, kept forever). 70_parsed
is a write-through cache of the per-filing ParsedFiling JSON – always re-derivable from raw,
so safe to drop/rebuild; it exists so a reprocess (re-consolidate/derive after a logic change)
skips re-parsing all filings, and so the lineage inputs[] in each consolidated doc resolve to a
real parsed document. 50/30/10 are the queryable Cosmos layers; 10_presentation is what the MCP
serves.
LAYER_MAP – which code owns which layer
Each pipeline-stage package directory is prefixed with its layer number so the
owner of every data layer is obvious. (Python module names can't start with a digit, so
the importable package keeps its fbl_* name; the number is also exposed as a LAYER
constant in each stage package.)
All AT stage packages live under products/agentic-firmenbuch/packages/ (abbreviated …/ below).
| Layer | Package (dir) | import | Store / container | Pydantic model | Sample |
|---|---|---|---|---|---|
99_registry | …/99_registry | fbl_registry | Cosmos 99_registry | RegistryDoc | §15a.0 doc |

Un-numbered. Shared (in packages/): core (fbl_core,
source-agnostic lineage/meta + metric contracts, config, storage) and
auth (fbl_auth, 00_accounts). AT-specific (in
products/agentic-firmenbuch/packages/): core_at
(fbl_core_at, UGB taxonomy + Firmenbuch domain models + ÖNACE + FI directories),
firmenbuch_client
(fbl_firmenbuch_client, HVD SOAP adapter),
orchestration
(fbl_orchestration, the --mode Job entrypoint),
mcp_server
(fbl_mcp_server, serving). Plus products/agentic-firmenbuch/tests/ (fixtures),
docs/ (incl. API probe findings).
Build status – live in production ✅
All build stages are implemented and the service is live in production: the multi-tenant MCP server is
deployed, the daily pipeline runs on a cron, and the backfill keeps growing the served slice. Since the V1
launch the register has gained semantic vector search, ÖNACE/WZ industry classification, register-change
events, German Handelsregister coverage through the unified endpoint, and the trial-then-Pro access model
described above. ruff + mypy --strict + pytest (with an 80% coverage gate) are green in CI;
deployment of the backend is manual after review.
Develop
uv sync # create the workspace venv
uv run pytest # all fixture/unit/integration tests (offline)
uv run mypy packages products # strict types (shared + products)
uv run ruff check packages products # lint
True end-to-end (live): a separate, env-flag-guarded test runs a few real FNRs
through every layer (API → 90_raw → … → 10_presentation → MCP). Skipped by default.
FBL_E2E=1 uv run pytest products/agentic-firmenbuch/tests/e2e -q # needs FIRMENBUCH_API_KEY
See products/agentic-firmenbuch/tests/e2e/. It uses in-memory stores + a tiny real pull –
no Azure, no full backfill (deployment is manual after review).

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
