BorgLayer MCP

The official MCP server for the BorgLayer API. It lets AI agents manage domains end to end on a BorgLayer account — search and register domains, transfer domains in from another registrar, manage DNS, set registrant details, and form a US LLC — all behind one scoped, per-request API key, paid from a prepaid USDC account balance.

Endpoint: https://mcp.borglayer.com/mcp (Streamable HTTP)

How it works

A BorgLayer API key (blrk_…) is an account with a prepaid USDC balance. Actions that cost money — registering a domain, transferring one in, forming an LLC — debit that balance; if it's too low the API returns insufficient_balance with a "top up" message and charges nothing. Read actions (search, list, DNS read, quotes) are free. Every tool maps to one scoped /api/v1 endpoint, and the key only does what its scopes allow.

Tools

Read

  • search_domains — search available domains, priced for your account
  • list_domains — the domains registered on your account
  • get_balance — your prepaid USDC balance (micro-USDC)
  • list_chains — supported chains + stablecoins for funding, each with its verified escrow contract

Domains

  • register_domain — register an available domain · debits balance · domains.register
  • transfer_in_domain — transfer a domain in with its auth/EPP code (free for free ccTLDs; others add a year) · domains.transfer
  • list_dns — a domain's DNS records · dns.read
  • add_dns_record / delete_dns_record — edit DNS (A/AAAA/CNAME/MX/TXT/NS/SRV/CAA) · dns.write

Registrant (owner) details — country-code TLDs require real registrant data

  • list_registrant_profiles · create_registrant_profile (registrant.write) · delete_registrant_profile

LLC formation

  • formation_quote — price a US LLC / entity with optional EIN + BOI · formation.read
  • create_formation — form the entity; debits balance then files · formation.write
  • get_formation — status of a formation order by reference · formation.read

Buying a listed marketplace domain through on-chain escrow is a separate, wallet-signed flow and is not part of this account API. Use the BorgLayer app or web marketplace for escrow purchases.

Authentication

Each agent supplies its own BorgLayer API key per request (Authorization: Bearer blrk_…). The server holds no secrets; all scopes and the prepaid-balance accounting are enforced server-side by the BorgLayer API. Get a key and top up its balance at borglayer.com.

Security

  • No secrets stored; the caller's key is used per-request and never persisted.
  • Fixed API base URL — no dynamic hosts (SSRF-safe).
  • All inputs schema-validated before the request is made.
  • Money-spending tools each require their own scope (domains.register, domains.transfer, formation.write) and are bounded by the account's prepaid balance, so an agent can never spend beyond what's funded.
  • Dangerous operations that give a domain away — transferring a domain OUT (revealing its auth code) and account-to-account push — are intentionally not exposed by this server.
