ANAF Romania Company Check + ChatGPT

Romanian company check with the free ANAF public web services, no API key: identity, VAT registration, VAT on cash basis, inactive status, split VAT and RO e-Factura status of up to 100 fiscal codes (CUI) on a given date, and the published annual financial statement indicators.

Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

(none: public data, no API key)

Step 1 — Set up the connector

Public data, no key: setup takes under a minute. The connector uses the free public web services of ANAF (Agenția Națională de Administrare Fiscală), the Romanian tax administration: the taxpayer and VAT status check (PlatitorTvaRest, version 9) and the published financial statements (bilanț). No account, API key or sign-in is needed.

1. In the connector store, pick ANAF Romania Company Check and install it. There is nothing to paste and no Authorize with Provider step.
2. Check it with anaf_get_company_vat_status, the fiscal code 14399840 and today's date: it returns the company's name, address, registration status and VAT status on that date.

Cloud and self-hosted work the same way: there is nothing to configure in either.

Identifiers: the fiscal code (CUI or CIF) is a number of up to 10 digits. VAT-registered companies quote it with the RO prefix (RO14399840); the connector always sends it without RO, as a number. nrRegCom is the Trade Register number, for example J40/372/2002.

Where to start: to check whether a supplier is real, active and VAT-registered on an invoice date, use anaf_get_company_vat_status for one company or anaf_get_companies_vat_status for up to 100, with the invoice or check date (YYYY-MM-DD). For the size of a company, anaf_get_financial_statement reads the published indicators of a year; the previous year is the safe first try, because the current year's statements appear only after filing.

What it reads: from the VAT check, the name, fiscal and registered office addresses, Trade Register number, registration status and date, CAEN activity code, legal form and competent tax office; whether the company is registered for VAT on that date, with its VAT periods and the legal ground of a cancellation; VAT on cash basis (TVA la încasare); whether ANAF declared it inactive, with the inactivation, reactivation and deregistration dates; split VAT; and whether it is in the RO e-Factura registry. Codes ANAF does not know come back in notFound. From the financial statement, indicators in lei (RON) with their Romanian labels: fixed and current assets, inventories, receivables, cash, liabilities, equity, net turnover, total revenue and expenses, gross and net profit or loss, and the average number of employees. Indicator numbers mean different things for different statement types, so the AI reads the label, not only the code.

Why the inactive flag matters: invoices from a taxpayer that ANAF declared inactive are a tax risk. Check on the invoice date and keep the date of the check.

Read-only: every tool only reads, so there is nothing to confirm and no tool is switched off at install.

Limits: ANAF allows at most 100 fiscal codes per VAT request and at most 1 request a second per client, and states that overloading the service is sanctioned. The AI spaces out calls when it checks many companies and puts up to 100 codes into one request.

The connector does not submit declarations or e-Factura invoices and does not change anything at ANAF.

Step 2 — Install the adapter

curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d

Step 3 — Add the connector in ChatGPT

Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide shows YOUR_SERVER_ID.

ChatGPT adds MCP servers as plugins on its Plugins page, on the web and on paid plans. Developer mode is no longer needed. In a Business workspace only admins and owners can add one; in Enterprise and Edu an admin can grant the Create plugins with MCPs permission.

1. Go to chatgpt.com/plugins, click Add, then Add custom MCP server.
2. Enter a name, e.g. Name: ANAF Romania Company Check.
3. Under Connection, enter the Server URL https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID and keep Authentication on OAuth.
4. Select I understand and want to continue, then Create as a plugin. When ChatGPT asks, sign in to AnythingMCP and allow access.
5. Install the new plugin from your personal plugins, then type @ in a chat and pick it.

Example prompts

• "Was CUI 14399840 registered for VAT and not inactive on 2026-10-15, the date of the invoice?"
• "Check these 20 supplier fiscal codes for today: which are inactive, not VAT-registered or not in RO e-Factura?"
• "Show the 2024 financial statement indicators for CUI 14399840: net turnover, net profit and average number of employees."
• "Does this company apply VAT on cash basis, and since when?"
• "When was RO14399840 registered, and what is its registered office and CAEN code?"

FAQ

Do I have to remove the RO prefix? You can type it either way; the connector sends the fiscal code to ANAF as a number without RO, as ANAF requires.

Does the free ChatGPT plan work with custom MCP servers? OpenAI documents custom MCP servers for paid plans only; the Free plan is not on its list.
