BorgLayer Marketplace MCP

An MCP server that lets AI agents search, appraise, and buy domains from the BorgLayer marketplace — across five blockchains, each settled through a verified, non-custodial escrow contract.

Endpoint: https://mcp.borglayer.com/sse

Supported chains & stablecoins

Every escrow is the same audited-pattern DomainEscrow contract: 0.99% platform fee (enforced on-chain), non-custodial, with a 2-of-3 multisig (Gnosis Safe) as the dispute resolver. Funds only ever move to the buyer, the seller, or the fee receiver.

Tools

• search_domains — search marketplace listings by keyword (domains.read)
• get_domain — a domain's details, listing, and appraisal (domains.read)
• get_appraisal — four-tier appraisal in USDC (domains.read)
• list_listings — browse active listings (listings.read)
• list_chains — supported chains + stablecoins, each with its verified escrow
• create_checkout — start an escrow checkout on a chosen chain + stablecoin (checkout.write; honours per-key spending limits)
• get_order / get_order_status — track an order (orders.read)

Authentication

Each agent supplies its own BorgLayer API key per request (Authorization: Bearer blk_live_…). The server holds no secrets; all scopes and spending limits are enforced server-side by the BorgLayer v1 API. Get a key at borglayer.com/partners/apply.

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.
• Purchases require the checkout.write scope + a per-key USDC spending limit, so an agent can never spend beyond its budget.
