WHAT IT DOES

What erc1155_uri does on MCP Ethers Wallet

AI agents call erc1155_uri to retrieve information from MCP Ethers Wallet without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why erc1155_uri is rated Low

ERC-1155 URI retrieval is a read-only operation that queries immutable token metadata from the blockchain. It has no side effects, does not modify data, and does not execute code or move funds. The absence of a description lowers confidence slightly, but the naming pattern and ERC-1155 standard strongly suggest a metadata query function.

From the tool's definition Tool name 'erc1155_uri' with no description provided. Based on naming convention and ERC-1155 standard, this retrieves the URI metadata for a token, analogous to tokenURI in ERC-721.
