OSIR Domain Name MCP ServerVerifiedFeatured

What is the OSIR Domain Name MCP Server?

The OSIR MCP server is a remote Model Context Protocol server run by OSIR, an ICANN-accredited domain registrar (IANA ID 4332). It gives any MCP client full domain lifecycle access: search, register, renew, transfer, DNS, WHOIS privacy, plus VPS, email hosting, app hosting, and one-page website publishing. It exposes 105 tools, 11 guided prompts, and the same operations over the A2A protocol for autonomous agents.

• Remote server, Streamable HTTP, no local install: https://be.osir.com/mcp/http
• 450+ domain extensions, 3 continents of infrastructure, 99.9999% uptime SLA
• Every purchase is quoted first and executed only after explicit confirmation, so an agent never spends money silently
• Free to connect; you pay only for the domains and services you order

Gemini CLI

No credentials are needed to connect. Availability, pricing, and name suggestions work immediately. Account operations ask you to sign in once through a device login link, which also works for headless agents.

Example prompts

• "Is brandname.com available? If not, suggest ten alternatives under $20 a year."

• "Point brandname.com at 203.0.113.10 and add a www CNAME."

How does it keep an agent from overspending?

Every tool that costs money returns a quote with the full price, including ICANN fees and payment processing, and then stops. Nothing is charged until the client calls executeConfirmedAction with the quoted action. Domain lock, auto-renew, and privacy toggles are separate explicit tools, so an agent cannot change them as a side effect. All account activity is logged and readable through getMyAuditLogs.
