AI agents invoke nrds to trigger processes or run actions in DomainKits. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
nrds can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access nrds gives an agent. Each links to the full case and the policy that stops it:

Search newly registered domains by keyword. Use for tracking competitor registrations, spotting trending keywords, monitoring brand squatting, or finding resale opportunities. Best practices: - keyword defaults to 'contain' matching, which searches all domains containing the keyword anywhere in the name. Use position=start, position=end, or position=middle to control where the keyword appears in the domain name. - Always use no_hyphen=true unless specifically looking for hyphenated domains — hyphenated registrations are mostly low-quality spam. - sort=tld_counter_desc surfaces keywords registered across many TLDs simultaneously — a strong signal of trending demand. - period=6+ filters for domains registered for 6-10 years, indicating serious projects rather than speculative 1-year registrations. - prefix_tld_count in results indicates how many TLDs share the same prefix — values above 10 suggest the keyword is being actively pursued by multiple registrants. - Disclose affiliate links when presenting register_url to users.. It is categorised as a Execute tool in the DomainKits MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the DomainKits MCP server in PolicyLayer and add a rule for nrds: 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 DomainKits. Nothing to install.
nrds is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the nrds 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.
Set action: deny in the PolicyLayer policy for nrds. 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.
nrds is provided by the DomainKits MCP server (https://api.domainkits.com/v1/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
