# bias_amplification_tracker

Tracks bias amplification in LLM outputs by analyzing fairness metrics from HuggingFace's model leaderboard. Designed for risk assessment personas to detect and quantify demographic, gender, or racial bias amplification in generated text. Accepts model identifiers or output samples, returns structured bias metrics and amplification trends.

- Homepage: https://github.com/getgapup/gapup-mcp-public
- Risk category: Read (Low risk)

- Server rate-limited: no
- Parameters: 4
- 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 |
| `modelId` | string | no | HuggingFace model identifier (e.g., 'facebook/opt-1.3b') |
| `outputSamples` | array | no | Array of LLM output strings to analyze for bias amplification |
| `demographicGroups` | array | no | Specific demographic groups to monitor (e.g., ['gender', 'race']) |

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": "bias_amplification_tracker",
    "arguments": {}
  }
}
```

## Why bias_amplification_tracker is rated Low

This tool reads and analyzes data from HuggingFace's model leaderboard, returning bias metrics. It is a read/query operation with no write, execute, or financial side effects. Severity is medium because misuse could involve feeding sensitive demographic data as input samples, and the results could be used to characterize or profile groups, but the tool itself only retrieves and analyzes information.

From the tool's own definition: "Tracks bias amplification... analyzing fairness metrics... returns structured bias metrics and amplification trends"

## Use case

AI agents call bias_amplification_tracker 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": {
    "bias_amplification_tracker": {}
  }
}
```
