Retrieve token holders and their balances for a given token.
AI agents call getTokenHolders 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 queries blockchain data (token holder information) without creating, modifying, deleting, or executing any autonomous actions. It is purely informational and read-only. Severity is low because disclosure of public blockchain data poses minimal direct risk; token holder lists are typically public information on transparent blockchains.
From the tool's definition Tool name and description indicate 'Retrieve token holders and their balances' — a pure data retrieval operation with no mutation or side effects.
Documented attack patterns abuse exactly the kind of access getTokenHolders 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 getTokenHolders:
{
"version": "1",
"default": "deny",
"tools": {
"getTokenHolders": {}
}
}getTokenHolders 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.
Retrieve token holders and their balances for a given token. 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 getTokenHolders: 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.
getTokenHolders 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 getTokenHolders 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 getTokenHolders. 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.
getTokenHolders 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.
