What this MCP does

Checks EU VAT numbers, finds company LEIs, and retrieves French and Norwegian business registry records.

check_vat_number
Check an EU VAT number
Use this when the user asks whether a business's VAT registration number is valid or which company it belongs to, for example "is ES A28015865 a valid VAT number?", "check the supplier VAT number on this invoice, ATU33864707" or "I need a VIES consultation number for this supplier". Pass the country code and the VAT number printed on the invoice or company letterhead, and requesterCountry with requesterVatNumber only when the user gives their own business VAT number for a consultation number. Returns whether the business is registered for VAT on the date of the check and, where the member state publishes it, the registered company name and address. Covers EU member states and Northern Ireland (XI), not GB. It only reads the public EU register of VAT-registered businesses; do not use it for VAT rates or to judge whether a business is trustworthy.

find_company_lei
Find a company's LEI
Use this when the user asks for the Legal Entity Identifier (LEI) of a company or wants to look up a LEI, for example "what is the LEI of Siemens AG?", "whose LEI is W38RGI023J3WT1HWRP32?" or "is the LEI of this German company still active?". Pass the company name (and a country code to narrow it) or the 20-character LEI. Returns each entity's LEI, legal name, status, legal form code, country and city, national registration number and the LEI's renewal dates. Sole proprietors are left out. Do not use it to find a private person, for companies that have no LEI (most small businesses), or for financial or credit information.

submit_feedback
Send feedback, bug report or tool request
Send feedback to the maintainers about a missing tool, broken links, a bug, or stale data. Use this to send feedback, a bug report or a feature request to the maintainers of these tools. Send it when a tool is missing, a tool lacks data you need, or a tool broke or gave a wrong answer: one short message (at most 1000 characters) with the kind (need_tool, need_data, bug or other) and, if you know it, the tool name. Returns a ticket id. Feedback is for these tools only: it is not a chat, and nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.
