# jailbreak_attempt_detector

Detects potential LLM jailbreak attempts by analyzing user input against NIST AI Risk Management Framework adversarial patterns. Designed for persona risk assessment, this tool evaluates text for common jailbreak techniques such as prompt injection, role-playing, or obfuscation. Inputs include the user message and optional context, returning a risk assessment with confidence scores and pattern matches. Ideal for real-time moderation in chat applications or API gateways.

- Recommended policy verdict: Allowed

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `async` | boolean | no | If true, returns a job_id immediately (<200ms) instead of waiting for the result. Poll the result with job_result(job_id). Use for slow tools to avoid client ti |
| `context` | string | no | Optional conversation context for better pattern matching |
| `message` | string | yes | User input text to analyze for jailbreak attempts |
| `threshold` | number | no | Confidence threshold for flagging attempts |

Parameters from the server's own tool schema.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "jailbreak_attempt_detector",
    "arguments": {
      "message": "<message>"
    }
  }
}
```

## Why jailbreak_attempt_detector is rated Low

This tool reads and analyzes input text to assess risk, returning a classification/score. It has no side effects — it does not modify data, execute code, or take financial action. The severity is medium because it processes potentially sensitive user inputs and its output could be misused (e.g., to fine-tune jailbreak attempts that evade detection), even though the tool itself is purely analytical.

From the tool's own definition: "Detects potential LLM jailbreak attempts by analyzing user input... returning a risk assessment with confidence scores and pattern matches"

## Use case

AI agents call jailbreak_attempt_detector to retrieve information from Gapup 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 Gapup Mcp:

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