POLICY

How to control Mcp Waifu Chat

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

Deny destructive operations

{
  "delete_user": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "create_user": {
    "limits": [
      {
        "counter": "create_user_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "chat": {
    "limits": [
      {
        "counter": "chat_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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