## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "compare_datasets",
    "arguments": {}
  }
}
```

## Why compare_datasets is rated Low

This tool performs a comparison operation across datasets, which is fundamentally a read operation. Comparisons analyze existing data without creating, modifying, or deleting information. Within an Obsidian RAG knowledge base context, this would query and retrieve data for analysis purposes only.

From the tool's own definition: "Tool name 'compare_datasets' and description 'Compare multiple datasets' indicate a data analysis operation that retrieves and examines multiple datasets without modifying them."

## Use case

AI agents call compare_datasets to retrieve information from Obsidian Elite RAG MCP 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 Obsidian Elite RAG MCP Server:

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