Get available agent categories and their counts. Useful for discovering what types of AI agents are available in the ecosystem.
AI agents call agents_get_categories 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 is a read-only operation that queries metadata about available agent categories. It retrieves information without modifying, executing, deleting, or committing financial transactions. The tool has minimal blast radius if misused by an AI agent, as it only returns informational data about category counts.
From the tool's definition The tool retrieves available agent categories and their counts with 'Get available agent categories' and 'discovering what types of AI agents are available' — indicating a query/discovery operation with no side effects.
Documented attack patterns abuse exactly the kind of access agents_get_categories 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 agents_get_categories:
{
"version": "1",
"default": "deny",
"tools": {
"agents_get_categories": {}
}
}agents_get_categories is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get available agent categories and their counts. Useful for discovering what types of AI agents are available in the ecosystem. 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 agents_get_categories: 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.
agents_get_categories 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 agents_get_categories 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 agents_get_categories. 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.
agents_get_categories 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.
