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

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

## Why active_drugs is rated Low

This tool retrieves state information about active prompt injections without modifying them. While the broader context (prompt injection attacks on AI agents) is concerning from a security design perspective, the tool itself performs only a read operation.

From the tool's own definition: "Tool name and description indicate a read-only operation: 'List currently active drugs and their remaining duration'."

## Use case

AI agents call active_drugs to retrieve information from Agent Drugs 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 Agent Drugs:

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