Leadgen MCP

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)

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.

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.
