Get USDs rebase event history. Shows yield distribution events, amounts, and APR over time.
AI agents call subgraph_usds_rebase_history 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 historical rebase events and financial metrics from what appears to be a blockchain subgraph. It retrieves and displays past data (yield distributions, amounts, APR) without creating, modifying, deleting, or executing any state-changing operations. The read-only nature of historical event queries and metrics display makes this a Read operation with low severity risk.
From the tool's definition Tool name contains 'get' operation (subgraph_usds_rebase_history) and description states 'Shows yield distribution events, amounts, and APR over time' - pure data retrieval with no modification or side effects.
Documented attack patterns abuse exactly the kind of access subgraph_usds_rebase_history 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 subgraph_usds_rebase_history:
{
"version": "1",
"default": "deny",
"tools": {
"subgraph_usds_rebase_history": {}
}
}subgraph_usds_rebase_history is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get USDs rebase event history. Shows yield distribution events, amounts, and APR over time. 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 subgraph_usds_rebase_history: 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.
subgraph_usds_rebase_history 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 subgraph_usds_rebase_history 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 subgraph_usds_rebase_history. 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.
subgraph_usds_rebase_history 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.
