WHAT IT DOES

What estimate_moolah_energy does on Justlend

AI agents call estimate_moolah_energy to retrieve information from Justlend without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why estimate_moolah_energy is rated Low

This tool only estimates/calculates costs prior to execution — it does not perform any transaction or modify any state. It is purely a read/query operation that returns cost projections.

From the tool's definition Estimate energy, bandwidth, and TRX cost for a JustLend V2 (Moolah) write operation BEFORE executing it.

RECOMMENDED RULE

The rule that runs estimate_moolah_energy safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Justlend, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For estimate_moolah_energy, this is the rule to start with:

estimate_moolah_energy Allowed

estimate_moolah_energy is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

How do I block estimate_moolah_energy completely? +

Set action: deny in the PolicyLayer policy for estimate_moolah_energy. 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.

What MCP server provides estimate_moolah_energy? +

estimate_moolah_energy is provided by the Justlend MCP server (justlend/mcp-server-justlend). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
