Get native token balances for multiple addresses
AI agents call get_multi_native_balances 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 retrieves balance information for multiple addresses on the BNB Chain without side effects. It is a read-only query operation that does not create, modify, delete, or execute any code or financial transactions. The low severity reflects minimal risk from misuse—an AI agent retrieving balance data cannot cause harm to blockchain state or user assets.
From the tool's definition Tool name 'get_multi_native_balances' and description 'Get native token balances for multiple addresses' indicate a retrieval operation that queries blockchain state without modifying data or executing transactions.

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_multi_native_balances:
{
"version": "1",
"default": "deny",
"tools": {
"get_multi_native_balances": {}
}
}get_multi_native_balances is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_multi_native_balances 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_multi_native_balances 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_multi_native_balances. 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_multi_native_balances 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.
