WHAT IT DOES

What list_user_domains does on Aibtc

AI agents call list_user_domains to retrieve information from Aibtc without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_user_domains is rated Low

This tool performs a read-only lookup of blockchain domains (BNS) associated with a given address. It retrieves existing information without creating, modifying, deleting, or executing any operations. The blast radius is minimal—misuse only exposes publicly available domain ownership information.

From the tool's definition Tool name 'list_user_domains' and description 'List all BNS domains owned by an address' indicate a query operation that retrieves and returns data without modifying state.

RECOMMENDED RULE

The rule that runs list_user_domains safely

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

list_user_domains Allowed

list_user_domains is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
