AI agents call getWNSTokenURI to retrieve information from Agentek Eth without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query to fetch metadata associated with a cryptocurrency name token. It retrieves existing data without creating, modifying, deleting, or executing any operations. The low severity reflects minimal risk: metadata lookups cannot harm systems or cause financial loss even if misused by an AI agent.
From the tool's definition Tool description states 'Get the token URI (metadata) for a .wei name' - this is a retrieval operation with no modification or side effects. It queries and returns metadata about an existing token.

PolicyLayer is an MCP gateway — it sits between your AI agents and Agentek Eth, and nothing reaches the server without passing your rules. This is the rule we recommend for getWNSTokenURI:
{
"version": "1",
"default": "deny",
"tools": {
"getWNSTokenURI": {}
}
}getWNSTokenURI is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get the token URI (metadata) for a .wei name. It is categorised as a Read tool in the Agentek Eth MCP Server, which means it retrieves data without modifying state.
Register the Agentek Eth MCP server in PolicyLayer and add a rule for getWNSTokenURI: 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 Agentek Eth. Nothing to install.
getWNSTokenURI 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 getWNSTokenURI 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 getWNSTokenURI. 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.
getWNSTokenURI is provided by the Agentek Eth MCP server (nanidao/agentek). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Agentek Eth, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
