Get current prices for tokens by contract address. Supports multiple chains.
AI agents call defi_get_token_prices 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 publicly available token price data across multiple chains. It performs no write, execution, destructive, or financial operations. While token prices are financially relevant information, the tool itself only reads/queries data without executing trades, moving funds, or modifying any state.
From the tool's definition Tool name contains 'get' and description states it 'Get current prices for tokens'; this is a retrieval operation with no side effects.

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