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

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

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

## Why jwt_analyzer is rated Low

JWT analysis is fundamentally a read operation—it inspects token structure, claims, signatures, and potential weaknesses without modifying or executing code. However, severity is elevated to 'medium' rather than 'low' because JWT analysis in an offensive security context could reveal sensitive authentication data or aid in crafting attacks.

From the tool's own definition: "Tool name 'jwt_analyzer' suggests analysis/inspection of JWT tokens. The empty description prevents definitive classification, but analysis tools typically read and examine data without modifying it."

## Use case

AI agents call jwt_analyzer to retrieve information from Hexstrike Ai 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 Hexstrike Ai:

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