`domain`	string	Yes	The domain to register, e.g. "coolname.xrpfi".
`refcode`	string	—	Optional referral code to embed in the registration link.

Parameters from the server's own tool schema.

RECOMMENDED RULE

The rule that runs register_domain safely

PolicyLayer is an MCP gateway: it sits between your AI agents and XRPName, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For register_domain, this is the rule to start with:

register_domain Rate-limited

register_domain stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about register_domain

What does the register_domain tool do? +

Get the link to register a .xrp / .xrpl / .xrpfi / .rlusd domain on xrpdomains.xyz. Registration is completed in the browser — the website handles the order and the user signs in their wallet there (the MCP does NOT build or broadcast the payment). Use when the user says "register X.xrpfi" or "buy X.xrp". Pass refcode if a referral applies. It is categorised as a Write tool in the XRPName MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does register_domain accept? +

register_domain accepts 2 parameters: domain, refcode. Required: domain. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on register_domain? +

Register the XRPName MCP server in PolicyLayer and add a rule for register_domain: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches XRPName. Nothing to install.

What risk level is register_domain? +

register_domain is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit register_domain? +

Yes. Add a rate_limit block to the register_domain rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block register_domain completely? +

Set action: deny in the PolicyLayer policy for register_domain. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides register_domain? +

register_domain is provided by the XRPName MCP server (@xrpname/xrpname-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
