Look up a transaction by ID on TRON. No auth required.
AI agents call get_transaction 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 performs a read-only lookup of transaction data on the TRON blockchain. It retrieves information about an existing transaction without modifying, executing, or deleting anything. The lack of authentication requirement reinforces that this is a passive query.
From the tool's definition Tool name 'get_transaction' combined with description 'Look up a transaction by ID on TRON' indicates a query operation that retrieves data without side effects. No modification, execution, or deletion of data is mentioned.
Attacks that exploit this kind of access
Look up a transaction by ID on TRON. 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_transaction: 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_transaction 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_transaction 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_transaction. 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_transaction 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.
