Get TRON network parameters (energy fee, bandwidth cost, etc.) with Merx price comparison. No auth required.
AI agents call get_chain_parameters 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 retrieves and queries TRON network state information and pricing data without modifying any state or executing operations. It is a straightforward read operation with no side effects. Misuse would only expose or display information, not harm assets or cause irreversible changes.
From the tool's definition Tool name 'get_chain_parameters' and description 'Get TRON network parameters' indicate data retrieval. Description explicitly states retrieval of network parameters (energy fee, bandwidth cost, etc.) and price comparison data.
Attacks that exploit this kind of access
Get TRON network parameters (energy fee, bandwidth cost, etc.) with Merx price comparison. 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 get_chain_parameters: 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.
get_chain_parameters 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_chain_parameters 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_chain_parameters. 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_chain_parameters 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.
