MOST DANGEROUS TOOLS

High Risk

The most dangerous Sensitive Lexicon tools

POLICY

How to control Sensitive Lexicon

PolicyLayer is an MCP gateway — it sits between your AI agents and Sensitive Lexicon, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "filter_sensitive_words": {
    "limits": [
      {
        "counter": "filter_sensitive_words_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "detect_sensitive_words": {
    "limits": [
      {
        "counter": "detect_sensitive_words_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.
