It does not interact with the XiaoHongShu platform or trigger any side effects. Classified as Read (the least severe category) because even harmless informational tools should be tracked, though the actual risk is negligible.

From the tool's definition Tool name 'hello' with description '一个简单的问候指令案例' (a simple greeting command example) indicates a basic greeting/test function with no data access, modification, or external effects.

The rule that runs hello safely

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

{
  "version": "1",
  "default": "deny",
  "tools": {
    "hello": {}
  }
}
