Get a quote for swapping tokens through the Yield Reserve. Uses protocol oracle prices for fair value swaps.
AI agents call yield_reserve_get_swap_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 queries swap pricing information from the Yield Reserve protocol using oracle prices. It does not execute transactions, transfer funds, or modify blockchain state—it merely returns informational quotes. This is a read-only operation with no side effects or financial obligation.
From the tool's definition The tool 'yield_reserve_get_swap_quote' retrieves a quote for token swaps; the description states it 'Get[s] a quote' which is a read operation. The word 'quote' indicates it returns information without executing a transaction or modifying state.
Documented attack patterns abuse exactly the kind of access yield_reserve_get_swap_quote 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 yield_reserve_get_swap_quote:
{
"version": "1",
"default": "deny",
"tools": {
"yield_reserve_get_swap_quote": {}
}
}yield_reserve_get_swap_quote is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a quote for swapping tokens through the Yield Reserve. Uses protocol oracle prices for fair value swaps. 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 yield_reserve_get_swap_quote: 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.
yield_reserve_get_swap_quote 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 yield_reserve_get_swap_quote 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 yield_reserve_get_swap_quote. 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.
yield_reserve_get_swap_quote 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.
