# Redact sensitive data

Redact sensitive data to comply with privacy regulations and prevent unauthorized access. Critical for agent systems handling PII and credentials.

## Redaction Levels

1. **By Data Type**: Redact all instances of a data type (e.g., all API keys)
2. **By Collection**: Redact entire agent/MCP collection
3. **Global**: Redact all data across all agents

## Important Note

{% hint style="warning" %}
Redacting data affects AI Red Teaming. Without stored values, agent requests can't be replayed and scanned.
{% endhint %}

## How Redaction Works

Values are replaced with `*****`:

```json
{"agent_prompt": "*****", "llm_response": "*****"}
```
