Get account information from indexer
AI agents call api_indexer_lookup_account_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 account information from an indexer service. There are no side effects, no data modification, no code execution, and no financial transactions. It is a straightforward data retrieval operation, making it a Read category tool with low severity since exposure would only allow information disclosure of account details already indexed on the blockchain.
From the tool's definition 'Get account information from indexer' — a lookup operation that retrieves account data without modifying, deleting, or executing operations. The verb 'get' and 'lookup' indicate read-only access to indexed account information.
Documented attack patterns abuse exactly the kind of access api_indexer_lookup_account_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_account_by_id:
{
"version": "1",
"default": "deny",
"tools": {
"api_indexer_lookup_account_by_id": {}
}
}api_indexer_lookup_account_by_id is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get account information from indexer. 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_account_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_account_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_account_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_account_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_account_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.
