Get asset information and configuration
AI agents call api_indexer_lookup_asset_by_id 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 asset information by ID, which is a read-only query operation. It does not create, modify, delete, execute code, or handle financial transactions. The blast radius of misuse is minimal as it only exposes asset metadata/configuration data.
From the tool's definition Tool name contains 'lookup' and description states 'Get asset information and configuration', indicating data retrieval without modification or side effects.
Documented attack patterns abuse exactly the kind of access api_indexer_lookup_asset_by_id 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 api_indexer_lookup_asset_by_id:
{
"version": "1",
"default": "deny",
"tools": {
"api_indexer_lookup_asset_by_id": {}
}
}api_indexer_lookup_asset_by_id is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get asset information and configuration. 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 api_indexer_lookup_asset_by_id: 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.
api_indexer_lookup_asset_by_id 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 api_indexer_lookup_asset_by_id 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 api_indexer_lookup_asset_by_id. 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.
api_indexer_lookup_asset_by_id 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.
