Broadcast a signed AccountPermissionUpdate transaction to the TRON blockchain. After broadcasting, verifies that the platform permissions were correctly applied. Use this after signing the transaction from build_permission_transaction. Requires authentication.
Part of the PowerSun MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call broadcast_signed_permission_tx to retrieve information from PowerSun without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though broadcast_signed_permission_tx only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Broadcast a signed AccountPermissionUpdate transaction to the TRON blockchain. After broadcasting, verifies that the platform permissions were correctly applied. Use this after signing the transaction from build_permission_transaction. Requires authentication.. It is categorised as a Read tool in the PowerSun MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for broadcast_signed_permission_tx. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the PowerSun MCP server.
broadcast_signed_permission_tx 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 broadcast_signed_permission_tx rule in your Intercept 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 Intercept policy for broadcast_signed_permission_tx. 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_signed_permission_tx is provided by the PowerSun MCP server (powersun/tron-energy-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
