Get information about oracle sources and providers used by Sperax. Shows oracle architecture and redundancy.
AI agents call oracle_get_sources 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 oracle configuration and provider information for display purposes only. It does not execute transactions, modify data, delete records, or trigger external operations. The 'Get' verb and informational nature clearly place it in the Read category with low severity, as misuse would only expose already-public oracle architecture details without enabling harm.
From the tool's definition Tool description states 'Get information about oracle sources and providers' and 'Shows oracle architecture and redundancy' — these are retrieval operations with no modification, deletion, or side effects.
Documented attack patterns abuse exactly the kind of access oracle_get_sources 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_sources:
{
"version": "1",
"default": "deny",
"tools": {
"oracle_get_sources": {}
}
}oracle_get_sources is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get information about oracle sources and providers used by Sperax. Shows oracle architecture and redundancy. 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_sources: 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_sources 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_sources 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_sources. 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_sources 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.
