Broadcast a signed TRON transaction with automatic energy optimization. If the target address lacks sufficient energy, MERX purchases the deficit at the best market price before broadcasting. One call: estimate, buy energy, wait for delegation, broadcast. Requires MERX_API_KEY with the
AI agents use resource_broadcast to commit financial operations through MERX - TRON Resource Exchange — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool performs two financially significant actions: (1) it autonomously purchases TRON energy at market price, committing real financial resources, and (2) it broadcasts a signed blockchain transaction, which is irreversible once confirmed.
From the tool's definition 'MERX purchases the deficit at the best market price before broadcasting' and 'buy energy' — the tool autonomously spends funds to purchase energy on-market, then broadcasts a signed transaction on the TRON blockchain.

One call: estimate, buy energy, wait for delegation, broadcast. Requires MERX_API_KEY with the. It is categorised as a Financial tool in the MERX - TRON Resource Exchange MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
Register the MERX - TRON Resource Exchange MCP server in PolicyLayer and add a rule for resource_broadcast: 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.
resource_broadcast is a Financial tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the resource_broadcast 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 resource_broadcast. 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.
resource_broadcast 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.
