WHAT IT DOES

What resolveENS does on Agentek Eth

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

RISK

Why resolveENS is rated Medium

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

RECOMMENDED RULE

The rule that runs resolveENS safely

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

resolveENS Rate-limited

resolveENS 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.
