Check energy, bandwidth, and TRX balance for any TRON address. No auth required.
AI agents call check_address_resources to retrieve information from MERX - TRON Resource Exchange without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and retrieves blockchain state information (energy, bandwidth, and balance metrics) for a given TRON address. It has no side effects, cannot modify data, and cannot trigger transactions or financial operations. It is a straightforward read operation on public blockchain data. The lack of authentication requirement further confirms it is informational only.
From the tool's definition Tool description explicitly states it 'Check energy, bandwidth, and TRX balance for any TRON address' - pure data retrieval with 'No auth required' indicating read-only access. No modification, deletion, or execution capabilities.
Attacks that exploit this kind of access
Check energy, bandwidth, and TRX balance for any TRON address. No auth required. It is categorised as a Read tool in the MERX - TRON Resource Exchange MCP Server, which means it retrieves data without modifying state.
Register the MERX - TRON Resource Exchange MCP server in PolicyLayer and add a rule for check_address_resources: 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 MERX - TRON Resource Exchange. Nothing to install.
check_address_resources 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 check_address_resources 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 check_address_resources. 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.
check_address_resources is provided by the MERX - TRON Resource Exchange MCP server (Hovsteder/merx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
