Returns the name, symbol, and URI of a given ERC6909 token ID from the Coins contract.
AI agents call getCoinTokenMetadata 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 metadata from a smart contract and returns data without side effects. It performs a simple read operation (analogous to a getter function) on token metadata, which is informational in nature. The blast radius of misuse is minimal — an attacker could only enumerate token information, not modify state, execute code, or move funds.
From the tool's definition Tool description states it 'Returns the name, symbol, and URI of a given ERC6909 token ID' — a retrieval operation with no modification or execution.
Documented attack patterns abuse exactly the kind of access getCoinTokenMetadata 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 getCoinTokenMetadata:
{
"version": "1",
"default": "deny",
"tools": {
"getCoinTokenMetadata": {}
}
}getCoinTokenMetadata 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.
Returns the name, symbol, and URI of a given ERC6909 token ID from the Coins contract. 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 getCoinTokenMetadata: 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.
getCoinTokenMetadata 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 getCoinTokenMetadata 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 getCoinTokenMetadata. 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.
getCoinTokenMetadata 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.
