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

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

## Why gov.fda-drug-events is rated Low

This tool queries and retrieves existing FDA FAERS (FDA Adverse Event Reporting System) data. The operations are read-only: searching by drug name and filtering by reaction term are data retrieval operations with no side effects. The tool returns informational results (seriousness flags, demographics, reactions) without creating, modifying, executing, deleting, or moving funds.

From the tool's own definition: "Tool description states 'Search by drug name' and 'Returns seriousness flags, patient demographics, reactions, drugs' — purely retrieval of public FDA adverse event data with no modification, deletion, or execution capabilities."

## Use case

AI agents call gov.fda-drug-events to retrieve information from Mcp 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 Mcp:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "gov.fda-drug-events": {}
  }
}
```
