Get recent events from the last N blocks for monitoring
AI agents call get_recent_events 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 historical event data from the blockchain for analysis and monitoring purposes. It performs no modifications, deletions, code execution, or financial operations. The blast radius of misuse is minimal—an agent querying unnecessary events would at worst consume resources or retrieve public blockchain data already visible on-chain.
From the tool's definition Tool name 'get_recent_events' and description 'Get recent events from the last N blocks for monitoring' indicate a retrieval operation with no side effects. The verb 'get' and purpose 'for monitoring' confirm read-only access to blockchain event data.
Documented attack patterns abuse exactly the kind of access get_recent_events 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 get_recent_events:
{
"version": "1",
"default": "deny",
"tools": {
"get_recent_events": {}
}
}get_recent_events is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get recent events from the last N blocks for monitoring. 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 get_recent_events: 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.
get_recent_events 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 get_recent_events 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 get_recent_events. 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.
get_recent_events 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.
