Get the metadata for an ERC1155 token (multi-token standard used for both fungible and non-fungible tokens). The metadata typically points to JSON metadata about the token.
AI agents call get_erc1155_token_metadata to retrieve information from BNB Chain MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only retrieval operation that queries token metadata from the blockchain. It has no side effects, does not execute code, and does not modify any data. The blast radius of misuse is minimal—an attacker could only obtain publicly available metadata about tokens.
From the tool's definition Tool name contains 'get_' and description states it retrieves 'metadata for an ERC1155 token' with no modification or execution capability mentioned. The function purely 'points to JSON metadata' without executing code or modifying state.
Documented attack patterns abuse exactly the kind of access get_erc1155_token_metadata gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and BNB Chain MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_erc1155_token_metadata:
{
"version": "1",
"default": "deny",
"tools": {
"get_erc1155_token_metadata": {}
}
}get_erc1155_token_metadata is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the metadata for an ERC1155 token (multi-token standard used for both fungible and non-fungible tokens). The metadata typically points to JSON metadata about the token. It is categorised as a Read tool in the BNB Chain MCP MCP Server, which means it retrieves data without modifying state.
Register the BNB Chain MCP server in PolicyLayer and add a rule for get_erc1155_token_metadata: 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 BNB Chain MCP. Nothing to install.
get_erc1155_token_metadata 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 get_erc1155_token_metadata 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 get_erc1155_token_metadata. 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.
get_erc1155_token_metadata is provided by the BNB Chain MCP server (nirholas/bnbchain-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
