Broadcast a pre-signed TRON transaction with auto energy delegation. Send your signed transaction data and PowerSun will delegate energy before broadcasting. Works with API key (balance deduction) or x402 USDC payment. Without authentication, returns cost estimate.

AI agents use broadcast_transaction to create or modify resources in Powersun Tron Mcp. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call broadcast_transaction repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Powersun Tron Mcp.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Broadcast a pre-signed TRON transaction with auto energy delegation. Send your signed transaction data and PowerSun will delegate energy before broadcasting. Works with API key (balance deduction) or x402 USDC payment. Without authentication, returns cost estimate.. It is categorised as a Write tool in the Powersun Tron Mcp MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Powersun Tron MCP server in PolicyLayer and add a rule for broadcast_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 Powersun Tron Mcp. Nothing to install.
broadcast_transaction is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the broadcast_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 broadcast_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.
broadcast_transaction is provided by the Powersun Tron MCP server (https://powersun.vip/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
