Verdatum documentation

Verdatum answers questions about organisations — companies, LLPs, charities, funds and other registered forms — inside your AI assistant. Ask in plain English; every answer names its sources and states its limits.

How it works

Verdatum is a hosted MCP service. When you ask a question, your assistant calls Verdatum; Verdatum resolves which organisation you mean, fetches what the question needs from official registers, patent offices and licensed providers, and returns an answer your assistant can quote: a plain-English summary, the structured detail behind it, the provenance of each claim, and any limitations.

Verdatum is an answer service, not an archive. It fetches on demand and does not keep your questions or the answers you received — see the privacy policy.

Connect Verdatum in Claude

From the connectors directory:

1. Open Settings, then Connectors, in the Claude web or desktop app.
2. Find Verdatum in the directory and choose Connect.
3. Sign in with your work email when prompted.

As a custom connector:

1. Open Settings, then Connectors, and choose Add custom connector.
2. Enter the URL https://mcp.verdatum.ai/mcp.
3. Sign in with your work email when prompted.

Verdatum is a standard MCP service using streamable HTTP and OAuth 2.0, so other MCP clients can connect to the same URL. Step-by-step instructions cover Claude only for now.

Sign-in and access

Access is contracted at organisation level. Sign in with your work email; if your organisation has a Verdatum contract, that is all you need — there is no software to install and no personal API key.

If you are told your organisation is not entitled, ask your organisation's administrator, or write to support@verdatum.ai with the email domain you signed in with. Not a customer yet? Write to sales@verdatum.ai.

Signing in tells Verdatum who you are so it can check your organisation's entitlement. The privacy policy explains what is processed and what is not.

What to ask

The coverage table on the home page shows what is covered, where, and with what stated limits. When a question falls outside coverage, the answer says so and names where the data lives instead of guessing.

Worked examples, ready to copy.

United Kingdom

• who owns Inchcape Shipping Services?
• who were Gymshark's shareholders below the 25% PSC threshold at its last confirmation statement that restated the full list?
• who holds security over Brompton Bicycle, since when, and is it outstanding or satisfied?
• tabulate financials of Lucy and Yak, UK

United States

• analyse revenue trend of Apple
• who reports a beneficial ownership stake above 5% in The Middleby Corporation?
• screen Haji Khairullah Haji Sattar Money Exchange for sanctions and tell me exactly which lists and versions you checked

Global, through public markets

• what is Tesco's latest share price and 3-month price history?
• what's the latest close and market facts for SAP's Frankfurt listing?
• compare the revenue and share price trend of IQE vs Intel

Global, through published patents

• what patents has International Business Machines published in the last two years?
• show the patent family and legal events for EP1000000B1

How to read an answer

Every answer carries the same parts.

• A summary in plain English. The direct answer to what you asked.
• Provenance. Filing numbers, register entries and provider identifiers stay attached to the facts they support. When sources disagree, both appear with their authority — official registers are the source of record, and the higher rank leads.
• Limitations. What Verdatum could not see is stated in the answer, with a suggested next step — so the gap is documented, not discovered later.
• Honest gaps. An empty result is never presented as proof of absence. Where data is held elsewhere — US security interests sit with state registers, for example — the answer names the register that holds it.

Answers are source-backed information, not financial, investment, legal, tax or accounting advice — see the terms of service.

When something goes wrong

If Verdatum will not connect, or an answer looks wrong or incomplete, email support@verdatum.ai. Verdatum does not store your questions or answers, so support cannot look up your conversation — include what you asked, the relevant part of the answer, and roughly when it happened.

The support page lists everything worth including and what to expect: a person replies within one UK business day.
