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

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

## Why search_person is rated Low

This tool retrieves and queries data from sanctioned person lists without creating, modifying, deleting, or executing any operations. It is a straightforward information lookup utility. Severity is low because read-only access to public/regulatory sanctioned-person lists poses minimal direct risk; misuse yields information exposure rather than operational or financial harm.

From the tool's own definition: "Tool description explicitly states it performs 'Fuzzy-search' and 'Returns matches with confidence scores' — a query operation with no modification or side effects."

## Use case

AI agents call search_person to retrieve information from Isir 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 Isir:

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