The onboarding tool is the one that changes a workflow: VAT, Companies House, PSC and registered address checked together, returned as a single decision with a risk score and the evidence bundle attached — the same work that normally means stitching four APIs together and deciding how to combine them.
A server over APITier's utility APIs: UK address and property lookup, company and compliance checks, validation of emails, phones, VAT and sort codes, plus barcode, QR and data-conversion helpers.
- A full UK business onboarding check in one call, returning PASS, REVIEW or FAIL with a risk score and the underlying data
- UK addresses verified against Royal Mail PAF, with canonical address, UPRN, UDPRN and per-delivery-point geocode
- A postcode expanded to its full PAF address list plus district, ward, county, country and geocode, and a UDPRN resolved to a full AddressBase record
- UK companies looked up on Companies House by name or number — status, address, SIC codes and filing health
- The Persons with Significant Control register for a company, which is what AML beneficial-ownership checks need
- Validation for VAT numbers, sort codes with a Vocalink modulus check, email addresses and phone numbers
- Barcodes and QR codes generated, data converted between formats, and an India pincode lookup
One MCP Key, which unlocks every service you subscribe to. Use the hosted endpoint at https://mcp.apitier.com, or run it locally through npx. Individual tools depend on individual subscriptions — the full UK onboarding check needs postcode, vat and leadAgent; the sort-code check needs no API key at all.
One command plus a key — npx -y @apitier/mcp-server, then supply credentials
