Get and parse the metadata for a specific token ID in an ERC1155 contract
AI agents call getERC1155Metadata to retrieve information from MCP Ethers Wallet 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 (ERC1155 token metadata) with no side effects. It follows the read category pattern: 'get', 'parse', and explicit metadata retrieval. The context of sibling tools (balanceOf, uri, tokenInfo queries) reinforces this is a data retrieval function. No funds are moved, no state is altered, no code is executed beyond metadata parsing.
From the tool's definition Tool name 'getERC1155Metadata' and description 'Get and parse the metadata for a specific token ID in an ERC1155 contract' indicate a read-only operation that retrieves and parses existing metadata without modifying state.
Documented attack patterns abuse exactly the kind of access getERC1155Metadata gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Ethers Wallet, and nothing reaches the server without passing your rules. This is the rule we recommend for getERC1155Metadata:
{
"version": "1",
"default": "deny",
"tools": {
"getERC1155Metadata": {}
}
}getERC1155Metadata is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get and parse the metadata for a specific token ID in an ERC1155 contract. It is categorised as a Read tool in the MCP Ethers Wallet MCP Server, which means it retrieves data without modifying state.
Register the MCP Ethers Wallet MCP server in PolicyLayer and add a rule for getERC1155Metadata: 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 MCP Ethers Wallet. Nothing to install.
getERC1155Metadata 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 getERC1155Metadata 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 getERC1155Metadata. 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.
getERC1155Metadata is provided by the MCP Ethers Wallet MCP server (crazyrabbitltc/mcp-ethers-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Ethers Wallet, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
