Leadgen — Romanian ONRC Business Registry (API + MCP)

Free, read-only access to Romania's official business registry (ONRC):

every registered company, its CAEN activities, legal representatives, status,

and 2025 financial statements — built from the state's own open-data dump and

exposed over a tiny HTTP API and an MCP server.

• 4,196,860 companies
• 19.3M CAEN activity records
• 3.68M legal representatives
• 4.64M status entries
• 2025 financial statements loaded

Live endpoints (free, no auth)

REST API — `https://onrc-api.adrianhomelab.com`

The landing page at `https://onrc-api.adrianhomelab.com/` documents the schema

with a worked example.

MCP server — `https://hermes.adrianhomelab.com/mcp` (Streamable HTTP). Point

any MCP client at that URL. Tools: `lookup_business`, `lookup_director`,

`lookup_financials`, `extract_contacts`, `lookup_domain`.

Where the data comes from

The registry is built from the official ONRC snapshot published on

data.gov.ro — no scraping, no third-party vendor. The

loaders stream the CKAN CSVs into SQLite and build an FTS5 full-text index

with diacritic-insensitive folding, so `popescu` matches `Popéscu` and `PAVĂL`

matches `paval`.

Repository layout

Run locally

python -m venv venv
venv/bin/pip install -r requirements.txt

# load the data (downloads the official snapshots — several GB)
venv/bin/python load_onrc.py --data-dir ./data --db ./data/onrc.db

# start the REST API
ONRC_DB=./data/onrc.db venv/bin/python api.py

# start the MCP server
ONRC_DB=./data/onrc.db venv/bin/python server.py --transport streamable-http --port 8766

Then hit `http://127.0.0.1:8767/docs`.

Notes on the data

• Diacritic-insensitive search — Romanian `ă â î ș ț` are folded to their

ASCII forms on both the index and the query.

• CUI vs registration code — a numeric `query` is matched against the CUI

(tax code) first, then the registration code.

• Read-only — the public surface only exposes lookups; there are no write

paths.
