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

  "jsonrpc": "2.0",

## Why list_products is rated Low

This tool retrieves and queries documentation metadata (product names, blurbs, versions, URLs) to enable discovery of valid product identifiers. It performs no creation, modification, deletion, execution, or financial operations. It is a pure read operation with minimal blast radius if misused by an AI agent—at worst, the agent would learn which products are documented.

From the tool's own definition: "Tool description states it 'List[s] the Free Battery Factory products' with documentation details and 'canonical URLs'. The verb 'list' and the purpose of discovery indicate data retrieval with no side effects."

## Use case

AI agents call list_products to retrieve information from Docs 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 Docs:

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