## Why rag_search is rated Low

The tool performs document retrieval and search operations ('search for similar documents', 'returns raw chunk data') which is a read-only operation. It queries the knowledge base but does not create, modify, delete, or execute any external operations.

From the tool's own definition: "Tool name: 'rag_search'. Description: 'Search for similar documents without generating context. Returns raw chunk data with scores.' This is a search/query operation that retrieves and returns data with no side effects."

## Use case

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

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches MCP RAG Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "rag_search": {}
  }
}
```
