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

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

## Why compare_savings is rated Low

This tool retrieves and presents analytical data about usage metrics and cost estimates. It has no side effects, does not modify any data, and does not execute operations or trigger external processes. It is purely informational/analytical in nature, fitting the 'Read' category for queries and analysis.

From the tool's own definition: "Tool performs comparison and analysis of metrics ('Compare token usage, time savings, and cost estimates', 'Shows total tool calls, tokens, estimated time saved, and cost')."

## Use case

AI agents call compare_savings to retrieve information from Nodebench 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 Nodebench:

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
