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

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

  "params": {
    "name": "reg_search",
    "arguments": {}

## Why reg_search is rated Low

This tool retrieves publicly available government documents and metadata from the Federal Register. It has no side effects—it only queries and returns information. The severity is low because the Federal Register is public data with no sensitive access controls, and misuse by an AI agent would result only in information gathering, not data modification, deletion, or any actionable harm.

From the tool's own definition: "Tool description states it 'Search[es] the Federal Register... for rules, proposed rules, notices, and presidential documents by keyword' and 'Returns each document's number, title, type, publishing agency, abstract, and URL.' These are all retrieval…"

## Use case

AI agents call reg_search to retrieve information from Livedatalink 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 Livedatalink:

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