Setup
Setup guide
- 11. In Switchy, open Settings → Integrations and click Connect next to OpenRegister. 2. You'll be prompted to paste an API key; generate one in your OpenRegister dashboard under Account → API Keys. 3. Grant the key read access to company data, documents, and monitors — no write scopes are required. 4. Click Test Connection; Switchy will call the Get Credit Usage tool to confirm the key works and show your remaining balance. 5. Open any Project, type '@OpenRegister check the profile for BASF SE' and send; the assistant will return the company's registration details, proving the connection is live. 6. To verify document retrieval, ask '@OpenRegister fetch the latest Handelsregister extract for [company name]' — you'll receive metadata and a download link. 7. If a query fails with a credit error, run '@OpenRegister show my credit usage' to see your balance and plan reset date.
What teammates see: by default, memories from OpenRegister are scoped to the Project (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

@OpenRegister search for all GmbH companies in Berlin's Mitte district founded after 2020 that are still active
OpenRegister returned 47 active GmbH companies in Berlin-Mitte founded since 2020. The results include company names, registration numbers, founding dates, and registered addresses. For example: TechFlow Solutions GmbH (HRB 234567, founded March 2021, Friedrichstraße 123), GreenEnergy Berlin GmbH (HRB 245891, founded July 2022, Unter den Linden 45), and DataVault Systems GmbH (HRB 256234, founded January 2023, Torstraße 78). Each entry shows current status and links to full profiles. This search consumed 10 credits from your account balance.
Advanced search queries cost 10 credits per page of results. The MCP requires an API key with sufficient credit balance. Search filters include legal form, location, founding date ranges, and status — useful for market research or competitive analysis, but credit costs add up quickly when exploring multiple result pages or running frequent queries.
@OpenRegister get the complete ownership structure and UBO information for Siemens AG, including all subsidiaries and beneficial owners
OpenRegister retrieved the ownership profile for Siemens AG (HRB 12300, Munich). The company shows a complex structure with institutional shareholders including BlackRock (6.2%), Norges Bank (3.1%), and public float (approximately 70%). Ultimate beneficial owners (UBOs) are identified through the ownership chain, with thresholds meeting German transparency requirements. The response includes 23 direct subsidiaries with majority stakes, historical ownership changes over the past 12 months, and links to related entity profiles. This realtime ownership query consumed 20 credits.
Realtime ownership and UBO queries cost 20 credits each — double the standard profile lookup. The data reflects official Handelsregister filings, so accuracy is high but updates lag behind real-world changes by days or weeks. Historical ownership polls are limited to recent changes; deep historical analysis requires multiple queries and careful credit budgeting.
@OpenRegister check our current credit balance and summarize which of our active monitors are consuming the most credits this month
Your OpenRegister account shows 8,450 credits remaining of your 10,000 monthly allocation (reset in 12 days). You've used 1,550 credits this period with no overage charges. Active monitors: 14 company monitors and 3 person monitors are running. The credit usage breakdown isn't itemized per monitor in this response, but the MCP confirms all monitors are active and will trigger notifications when changes occur. Monitor setup and listing operations cost zero credits; only the triggered data retrievals consume your balance.
Credit usage checks are free, making them safe for frequent budget monitoring. However, the MCP cannot predict future credit burn from active monitors — that depends on how often monitored entities file changes. Consider this when setting up many monitors on a limited credit plan. The zero-cost monitor list operation helps audit your surveillance footprint without spending credits.
Use-case deep-dives
When OpenRegister beats manual registry checks for vendor onboarding
A 6-person finance team vetting 40+ new vendors per quarter used to spend 20 minutes per company downloading PDFs from Handelsregister and cross-checking ownership. OpenRegister's Get Company Data and Get Document tools pull the same official records in under 10 seconds, returning structured JSON for financials, UBOs, and current ownership. The 10-credit cost per lookup is trivial compared to the labor saved. The threshold: if you're only onboarding 2-3 vendors a month, the API key setup and credit management overhead isn't worth it—just pull the PDFs manually. But at 10+ vendors monthly, OpenRegister turns a compliance chore into a one-click Switchy workflow that logs every check for audit trails.
How OpenRegister automates bankruptcy alerts for customer portfolios
A 3-person credit team at a B2B SaaS company monitors 200 enterprise customers for insolvency risk. Before OpenRegister, they relied on quarterly manual checks or expensive credit bureau subscriptions. Now they use List Monitors to track every customer company and Get Insolvency to pull full proceeding histories when a flag fires. Each insolvency lookup costs 10 credits, but the real win is the monitor API: it's zero-credit and catches filings within 24 hours. The trade-off: OpenRegister only covers German Handelsregister data, so if your portfolio spans multiple EU jurisdictions, you'll need a second tool. For German-heavy portfolios, though, this MCP turns credit monitoring into a Switchy background task that pings Slack when a customer hits trouble.
When OpenRegister's URL lookup shortens enterprise sales cycles
A 5-person sales ops team at a logistics startup qualifies 50+ inbound leads weekly. They used to Google company names, guess at legal entities, and manually verify registration details before routing to AEs. OpenRegister's Look Up Company by URL tool takes the lead's website, returns the official company ID and contact data in one 10-credit call, then pipes that into Get Company Data for employee count and financials. The entire enrichment flow runs in Switchy as a single prompt: paste the URL, get back a structured lead profile. The limit: if your leads are mostly non-German or you need real-time headcount (not registry-reported), this MCP won't cover it. But for DACH-focused sales teams, it cuts lead qualification from 10 minutes to 10 seconds.
Frequently asked
What does the OpenRegister MCP let me do in Switchy?
It pulls German company registry data — profiles, financials, ownership chains, insolvency filings, and official Handelsregister documents — directly into your AI workspace. You can search by name or URL, track management positions, resolve ultimate beneficial owners, and monitor entities for changes. Every lookup costs OpenRegister credits; the MCP handles auth and returns structured data your team can query or export.
Do I need an OpenRegister API key to connect this MCP?
Yes. Generate an API key from your OpenRegister account dashboard and paste it into Switchy's connection form. The key ties usage to your OpenRegister credit balance; free accounts work but have lower quotas. Anyone on your Switchy workspace who uses the MCP will draw from the same credit pool, so connect with a key you're comfortable sharing across the team.
Can the OpenRegister MCP file documents or update company records?
No. It's read-only. You can fetch profiles, search companies, download official PDFs, and list insolvency proceedings, but you can't submit filings or edit registry data. If you need to lodge a change with the Handelsregister, do that through the official portal or a Notar; the MCP only surfaces what's already published.
How is this different from searching the Handelsregister website directly?
The MCP returns machine-readable JSON instead of HTML tables, so your AI can parse ownership graphs, compare financials across queries, or trigger workflows when a monitor fires. You also get autocomplete search for one credit versus ten, and you can pull UBO chains or insolvency timelines in a single call. The trade-off is every request costs credits; manual lookups on the public portal are free.
Who on my team should connect the OpenRegister MCP?
Whoever owns your OpenRegister subscription and is comfortable with the team burning credits on queries. Finance, legal, or compliance leads are typical. Once connected, any workspace member can run searches or pull documents, so set usage expectations up front. Check the Get Credit Usage tool regularly to avoid surprise overage charges at month-end.
