Get current prices for all collateral assets from Chainlink oracles. Shows price, last update time, and freshness status.
AI agents call oracle_get_all_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 performs a read-only query of oracle price data. It fetches information without any side effects, creation, modification, deletion, or financial transaction. The data retrieved could inform financial decisions, but the tool itself only reads existing price data from a trusted oracle source, making it a Read category tool with low severity.
From the tool's definition Tool retrieves current prices and metadata ('price, last update time, and freshness status') from Chainlink oracles with no modification or execution capability.
Documented attack patterns abuse exactly the kind of access oracle_get_all_prices 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 oracle_get_all_prices:
{
"version": "1",
"default": "deny",
"tools": {
"oracle_get_all_prices": {}
}
}oracle_get_all_prices is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get current prices for all collateral assets from Chainlink oracles. Shows price, last update time, and freshness status. 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 oracle_get_all_prices: 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.
oracle_get_all_prices 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 oracle_get_all_prices 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 oracle_get_all_prices. 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.
oracle_get_all_prices 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.
