Common questions

Is Borglayer MCP safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 39 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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.

Robinhood Chain	USDG	`0x91749468…9274a`

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.
