WHAT IT DOES

What set_primary_domain does on XRPName

AI agents use set_primary_domain to create or update resources in XRPName, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your XRPName environment.

Parameter	Type	Required	Description
`domain`	string	Yes	The domain to set as primary, e.g. "alice.xrp".

Parameters from the server's own tool schema.

RISK

Why set_primary_domain is rated Medium

An AI agent can call set_primary_domain faster than any human can review: one bad instruction and it creates or modifies resources in XRPName by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs set_primary_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 set_primary_domain, this is the rule to start with:

set_primary_domain Rate-limited

set_primary_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 set_primary_domain

What does the set_primary_domain tool do? +

Get the link to set a domain as your wallet's primary (the name shown by default for your address). Setting primary is completed in the browser — the website handles it and your wallet signs there (the MCP does NOT build or broadcast the transaction). Use when the user says "make X.xrp my primary" or "set X.xrpfi as my main domain". The wallet must already own the domain. 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 set_primary_domain accept? +

set_primary_domain accepts 1 parameter: domain. Required: domain. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on set_primary_domain? +

Register the XRPName MCP server in PolicyLayer and add a rule for set_primary_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 set_primary_domain? +

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

Can I rate-limit set_primary_domain? +

Yes. Add a rate_limit block to the set_primary_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 set_primary_domain completely? +

Set action: deny in the PolicyLayer policy for set_primary_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 set_primary_domain? +

set_primary_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.
