AI agents call get_assets 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 tool performs a read-only operation to fetch asset holdings information for a given cryptocurrency address. It has no side effects, does not execute transactions, and does not modify any data. The blast radius of misuse is minimal—an attacker could only retrieve holdings information for a queried address, which is typically public blockchain data. Therefore, it is classified as 'Read' with low severity.
From the tool's definition Tool name 'get_assets' and description 'Get Assets holdings by CryptoAddress' indicate a query operation that retrieves data about cryptocurrency holdings without modifying or executing any transactions.
Documented attack patterns abuse exactly the kind of access get_assets 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_assets:
{
"version": "1",
"default": "deny",
"tools": {
"get_assets": {}
}
}get_assets is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get Assets holdings by CryptoAddress. 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_assets: 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_assets 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_assets 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_assets. 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_assets 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.
