Get RSA public key for encrypting gift card codes in external integrations.
AI agents call BinanceGiftCardRsaPublicKey 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 operation by fetching a public key resource. While RSA public keys are used in cryptographic operations, the tool itself only retrieves existing data without executing code, modifying state, or initiating transactions. The severity is low because public keys are meant to be publicly accessible and their exposure does not directly compromise security.
From the tool's definition Tool retrieves an RSA public key for encryption purposes. The description indicates this is a 'Get' operation that returns a public cryptographic key used for external integrations, with no modification or execution of code.
Documented attack patterns abuse exactly the kind of access BinanceGiftCardRsaPublicKey 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 BinanceGiftCardRsaPublicKey:
{
"version": "1",
"default": "deny",
"tools": {
"BinanceGiftCardRsaPublicKey": {}
}
}BinanceGiftCardRsaPublicKey is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get RSA public key for encrypting gift card codes in external integrations. 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 BinanceGiftCardRsaPublicKey: 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.
BinanceGiftCardRsaPublicKey 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 BinanceGiftCardRsaPublicKey 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 BinanceGiftCardRsaPublicKey. 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.
BinanceGiftCardRsaPublicKey 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.
