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

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

## Why search is rated Low

Despite the empty description, the tool name 'search' combined with the server's documented buyer-side workflow context (which lists search as a primary capability) and the presence of complementary read-only tools (get_item, get_watchlist, get_won_items) strongly indicates this retrieves or queries eBay listings with no side effects.

From the tool's own definition: "Tool name is 'search' on an eBay buyer-side MCP server in a context of querying items (sibling tools include get_item, get_watchlist, get_won_items). The server description emphasizes 'search, watch, bid, buy' workflows."

## Use case

AI agents call search 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": {
    "search": {}
  }
}
```
