Retrieve the source code, ABI, and metadata of a verified smart contract by its address.
AI agents call getSmartContract 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.
The tool retrieves publicly available smart contract information (source code, ABI, metadata) from a blockchain. It performs no state changes, does not execute contract logic, and does not move funds or trigger transactions. The data is already public on the blockchain. Even in a misuse scenario, an AI agent could only gather information, not cause harm. This is purely a Read operation.
From the tool's definition Tool description states 'Retrieve the source code, ABI, and metadata of a verified smart contract by its address' — this is a query/fetch operation with no modifications, deletions, or execution of contract functions.
Documented attack patterns abuse exactly the kind of access getSmartContract 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 getSmartContract:
{
"version": "1",
"default": "deny",
"tools": {
"getSmartContract": {}
}
}getSmartContract is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve the source code, ABI, and metadata of a verified smart contract by its address. 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 getSmartContract: 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.
getSmartContract 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 getSmartContract 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 getSmartContract. 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.
getSmartContract 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.
