WHAT IT DOES

What hello does on Daniel LightRAG MCP Server

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

RISK

Why hello is rated Low

This is a basic informational/diagnostic tool that returns a greeting message. It performs no queries, modifications, deletions, or external operations. It has minimal blast radius if misused by an AI agent.

From the tool's definition Tool name 'hello' with description 'Say hello' indicates a simple greeting/test operation with no data access, modification, or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs hello safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Daniel LightRAG MCP Server, 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:

hello Allowed

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

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Daniel LightRAG MCP Server, apply this rule, and every hello call is checked against it from then on.
