Gets fee growth globals and protocol fee data for a Uniswap V3 pool.
AI agents call getPoolFeeData 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 retrieves and queries fee-related data from a Uniswap V3 pool. It performs no state changes, does not execute code or transactions, and does not move funds or delete data. The read-only nature of data retrieval from a blockchain query carries minimal risk of misuse.
From the tool's definition Tool description states it 'Gets fee growth globals and protocol fee data' — purely retrieval of existing data with no modification, creation, deletion, or execution of operations.
Documented attack patterns abuse exactly the kind of access getPoolFeeData 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 getPoolFeeData:
{
"version": "1",
"default": "deny",
"tools": {
"getPoolFeeData": {}
}
}getPoolFeeData is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Gets fee growth globals and protocol fee data for a Uniswap V3 pool. 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 getPoolFeeData: 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.
getPoolFeeData 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 getPoolFeeData 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 getPoolFeeData. 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.
getPoolFeeData 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.
