kyc_onboard_ukLABSCO SUMMARY
KYC and address verification, as calls instead of as four separate vendor integrations.
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.
What it is
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.
What you get
- 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
Requirements
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.
Setup effort
One command plus a key — npx -y @apitier/mcp-server, then supply credentials
USE CASES
01
Onboarding a new UK business customer
Run the combined check and read back PASS, REVIEW or FAIL with the company, PSC, VAT and address results behind it.
02
Cleaning up an address before it goes on a label
Verify it against Royal Mail PAF and take the canonical form and UPRN back, rather than shipping what someone typed.
03
Checking who really owns a company you are about to trade with
Look the company up on Companies House, then read its Persons with Significant Control register.
04
Validating payment and tax details before you store them
Run the sort code through a Vocalink modulus check and the VAT number through validation.
05
Filling in an address form from a postcode
Expand the postcode into its full PAF address list with the administrative geography attached.
06
Cleaning a contact list before a campaign
Validate the email addresses and phone numbers in bulk instead of discovering the bad ones on send.
