Given a wallet address, return all token balances the account holds, including coin metadata.
AI agents call getAccountPortfolio 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 is a read-only operation that queries blockchain state to retrieve public account portfolio information. It has no side effects, cannot modify data, and poses minimal risk even if called repeatedly or with incorrect inputs. The only potential concern is information disclosure of wallet holdings, but this is already public blockchain data.
From the tool's definition Tool returns token balances and metadata for a given wallet address with no modification capability. Description uses 'return' indicating data retrieval only, not creation, modification, or deletion.
Documented attack patterns abuse exactly the kind of access getAccountPortfolio gives an agent:
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 getAccountPortfolio:
{
"version": "1",
"default": "deny",
"tools": {
"getAccountPortfolio": {}
}
}getAccountPortfolio is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Given a wallet address, return all token balances the account holds, including coin metadata. 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 getAccountPortfolio: 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.
getAccountPortfolio 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 getAccountPortfolio 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 getAccountPortfolio. 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.
getAccountPortfolio 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.
Free to start. No card required.
