## Why ebay_get_negative_keyword is rated Low

This tool retrieves negative keyword data from the eBay Marketing API. The 'get' verb and retrieval-focused description indicate a read-only operation that queries existing data without creating, modifying, deleting, or executing any actions. The blast radius of misuse is minimal—at worst, an agent could retrieve data about marketing keywords already known to the seller.

From the tool's own definition: "Tool name contains 'get' and description states 'Get negative keyword' indicating data retrieval with no modification or side effects."

## Use case

AI agents call ebay_get_negative_keyword to retrieve information from Ebay 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 Ebay:

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