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

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

## Why web_research is rated Low

Web research, fact-checking, and item comparison are fundamentally retrieval operations with no side effects. The tool queries external data sources but does not create, modify, delete, execute code, or commit financial transactions. While it could theoretically be used to research sensitive topics, the tool itself has no capability to act on that information beyond returning results.

From the tool's own definition: "Tool name is 'web_research' with description stating 'Search the web, fact-check claims, compare items, or conduct deep research.' These are all read-only operations that retrieve information without modifying external systems."

## Use case

AI agents call web_research to retrieve information from Hamza Agent Hub 252 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 Hamza Agent Hub 252:

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