Resolve ENS name to address or perform reverse lookup from address to ENS name
AI agents call resolveENS to retrieve information from Boosty MCP DeFi Platform without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only performs a lookup/query operation — resolving an ENS name to an Ethereum address or vice versa. It retrieves publicly available blockchain data with no side effects, no state changes, and no financial implications. Even in a high-risk DeFi platform context, this specific tool is purely informational.

Documented attack patterns abuse exactly the kind of access resolveENS gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Boosty MCP DeFi Platform, and nothing reaches the server without passing your rules. This is the rule we recommend for resolveENS:
{
"version": "1",
"default": "deny",
"tools": {
"resolveENS": {}
}
}resolveENS is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Resolve ENS name to address or perform reverse lookup from address to ENS name. It is categorised as a Read tool in the Boosty MCP DeFi Platform MCP Server, which means it retrieves data without modifying state.
Register the Boosty MCP DeFi Platform MCP server in PolicyLayer and add a rule for resolveENS: 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 Boosty MCP DeFi Platform. Nothing to install.
resolveENS is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the resolveENS 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 resolveENS. 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.
resolveENS is provided by the Boosty MCP DeFi Platform MCP server (nirholas/boosty). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Boosty MCP DeFi Platform, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
