agentic-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.

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).

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, …):

1. Get a free API key at agentic-firmenbuch.at – just a verified email.

2. Add the server. Claude Code (terminal), one line:

   claude mcp add --scope user --transport http agentic-firmenbuch https://mcp.agentic-firmenbuch.at/mcp --header "X-API-Key: <your-key>"

   GitHub Copilot / VS Code: 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: URL https://mcp.agentic-firmenbuch.at/mcp, header X-API-Key: <your-key>.

3. 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_details and 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 connector with the URL https://mcp.agentic-firmenbuch.at/mcp and a one-time email login (OAuth, no key).

Available MCP tools

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
        │   ├── firmenbuch_client, 99_registry, 90_ingest, 70_parse,
        │   │   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)

99_registry (foundation: all companies)  →  90_raw (Blob)  →  70_parsed (Blob)  →  50_consolidated  →  30_derived  →  10_presentation  →  MCP
                                                                        (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).

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 – Version 1 complete ✅

All ten §15 build stages are implemented, each committed in order, each with a passing Definition of Done. ruff + mypy --strict + pytest (with an 80% coverage gate) are green in CI. The HVD API was live-probed (§16 resolved) and the full chain raw→present was verified on live data end-to-end.

• Stage 10: an auth-restricted coverage tool (XML vs PDF-only vs none, by format/status – §11) and GitHub Actions CI (uv sync → ruff → ruff format → mypy --strict → pytest with an 80% coverage gate, plus a Bicep-compile job).

What's left to operate (not code): provision Azure (infra/setup.sh, billable), push the FIRMENBUCH_API_KEY to Key Vault, build/push images, then run the Initial Load (sync-registry → backfill-ingest → backfill-process) and enable the daily cron.

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).
