OpenRegister MCP with Claude: Faster German Company Due Diligence
The short answer
Claude connects to OpenRegister through the Model Context Protocol (MCP) or the direct API, using an API key. Once connected, Claude can look up German companies, inspect ownership structures, review financial records and monitor insolvency updates from one request. Access is limited to what your organisation allows, and people approve any action that matters.
What is OpenRegister?
OpenRegister provides structured German register data covering companies, people, ownership, finances, insolvency, documents, monitoring and usage. It brings information from German public-register sources into one place, so businesses can check counterparties, support compliance work and track changes without searching each register by hand. It is typically used by finance teams, compliance officers, legal departments, sales operations and risk analysts working with German companies.
How Claude connects to OpenRegister through MCP
The Model Context Protocol is an open standard that lets Claude securely use other software. Think of it as a universal adapter between Claude and a tool. Through OpenRegister's MCP server, or its direct API, Claude can ask questions of the register data and receive structured answers, all within permissions your organisation sets.
Once connected, Claude can typically search for a German company, read its registered details, trace ownership structures, review available financial records and check monitored companies for insolvency updates. You ask in ordinary language, for example: show me the shareholders of this company and any recent insolvency notices. Claude then gathers the answer from the register data.
Permissions and approvals keep people in charge. We use a dedicated API key with the least access needed, restrict which data Claude can read, and log every query. Where a result feeds a decision, such as onboarding a supplier or escalating a risk, a named person reviews and approves it before anything happens.
What you can automate
Supplier and customer onboarding checks
Before approving a new German supplier or customer, a procurement or finance team member asks Claude to pull the company's registered details, directors and ownership structure. Claude summarises the key facts into a short onboarding note, flagging anything that needs a closer look. The reviewer still makes the final decision.
Ownership mapping for compliance
Compliance officers often need to understand who ultimately controls a company. Claude can trace ownership links through the register data and present them as a readable chain. This speeds up know-your-customer reviews and gives the compliance team a clear, documented starting point.
Insolvency monitoring for key accounts
Finance and credit teams can monitor a list of important German counterparties. When an insolvency update appears, the workflow notifies the account owner, who asks Claude for the latest details and decides on next steps such as tightening payment terms or pausing new orders.
Financial record review for credit decisions
Credit analysts can ask Claude to retrieve available financial records for a German company and set out key figures over time. This helps analysts prepare credit memos faster. Claude presents the data; the analyst interprets it and records the credit decision.
Sales prospect research
Sales operations teams can ask Claude to profile a German prospect, including its registration details, ownership and recent activity. The output can be added to the CRM record, giving account executives context before a call without hours of manual searching.
