Get a swap quote for trading between SPA, USDs, and other tokens. Returns expected output amount and price impact.
AI agents call swap_get_quote 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 quote data for potential trades but does not execute the actual swap, transfer funds, or commit any financial obligation. It is purely informational and read-only, similar to querying a price feed or calculator. No data is modified, no code is executed, and no financial transaction occurs.
From the tool's definition The tool description states it 'Get a swap quote' and 'Returns expected output amount and price impact'. The word 'Get' and 'Returns' indicate a read operation that retrieves pricing information without executing any transaction or modifying state.

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