New here? Start with the connect your agent guide (four steps, client how-tos, prompts and the safety rules). This page is the full install list.

One-click MCP install

Full MCP endpoint https://stabledomains.net/api/mcp (search, buy, DNS). Directories and read-only chat apps can use https://stabledomains.net/api/mcp/discover instead — same search and quotes, no purchase tools, a checkout link when someone wants to buy. Search works without a key. To buy or manage domains, sign in with OAuth when your client asks, or add Authorization: Bearer sd_live_... (free key: curl -s -X POST https://stabledomains.net/api/v1/agents/signup).
