## Why list_local_eas is rated Low

This tool performs a simple enumeration or listing operation on local files/folders. It retrieves data (names and metadata of Expert Advisors) with no side effects, no code execution, no data modification, and no destructive impact. This is a classic Read operation—similar in character to 'list_experts' on the same server.

From the tool's own definition: "Tool name 'list_local_eas' and description 'List EAs in the local development folders' indicate a read-only operation that retrieves information about Expert Advisors without modifying or executing them."

AI agents call list_local_eas to retrieve information from MCP MetaTrader 4 Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
