Mcp Server
Wraps APITier's utility APIs into MCP tools for validation, lookup, and data transformation workflows. The standout is kyc_onboard_uk, which runs a full UK business onboarding check in one call: VAT validation via HMRC/VIES, Companies House verification, PSC beneficial ownership lookup, and Royal Mail address confirmation, returning a pass/review/fail decision with risk score. Also includes UK postcode and UPRN lookups against AddressBase, sort code validation, email and phone verification, Indian PIN code lookup, and barcode/QR generation. Works over stdio for Claude Desktop or as a hosted HTTP endpoint. Requires an MCP key from apitier.com that unlocks tools based on your active service subscriptions.
