27 tools. 8 can modify or destroy data without limits.
1 destructive tool with no built-in limits. Policy required.
Last updated:
Financial operations (withdraw_earnings) can move real money. An agent caught in a loop could drain accounts before anyone notices.
Write operations (broadcast_transaction, configure_auto_selling, register) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Execute tools (build_permission_transaction, execute_swap, trigger_vote) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
Intercept sits between your agent and PowerSun. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.
npx -y @policylayer/intercept scan -- npx -y @powersun/tron-energy-mcp withdraw_earnings:
rules:
- action: deny Financial tools should be explicitly enabled per use case, not open by default.
broadcast_transaction:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
broadcast_signed_permission_tx:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The PowerSun server exposes 1 financial tools including withdraw_earnings. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. Intercept lets you block financial tools by default or set per-tool rate limits.
The PowerSun server has 4 write tools including broadcast_transaction, configure_auto_selling, register. Set rate limits in your policy file -- for example, rate_limit: 10/hour prevents an agent from making more than 10 modifications per hour. Intercept enforces this at the transport layer.
27 tools across 4 categories: Execute, Financial, Read, Write. 19 are read-only. 8 can modify, create, or delete data.
One line change. Instead of running the PowerSun server directly, prefix it with Intercept: intercept -c powersun-tron-energy-mcp.yaml -- npx -y @powersun/tron-energy-mcp. Download a pre-built policy from policylayer.com/policies/powersun-tron-energy-mcp and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
Set budgets, approvals, and hard limits across MCP servers.
