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

```json
{
  "jsonrpc": "2.0",

    "name": "search-wikipedia",

## Why search-wikipedia is rated Low

This tool only retrieves and displays information from Japanese Wikipedia articles. It performs a search query and returns summaries—classic read-only retrieval operations. There is no data modification, deletion, execution of arbitrary code, or financial impact. The minimal blast radius if misused would be excessive API calls or information gathering from public sources, both low-severity concerns.

From the tool's own definition: "Tool description: 'Searches Japanese Wikipedia and returns article summaries.' The tool retrieves and queries existing public data with no modifications, deletions, or side effects."

## Use case

AI agents call search-wikipedia to retrieve information from Minimal 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 Minimal:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "search-wikipedia": {}
  }
}
```
