MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Personal Brain tools

Financial · High subscriptions_audit The tool explicitly supports adding and cancelling recurring subscriptions, which are financial obligations. Write · Low add_recipe This tool creates new recipe entries in a personal cookbook database. Write · Low content_queue This tool primarily enables creating and updating entries in a personal content queue. Write · Medium dietary_prefs This tool retrieves and modifies personal dietary information.

25 of Personal Brain's 54 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Personal Brain

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

Block financial tools by default

{
  "subscriptions_audit": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Requires human approval."
      }
    ]
  }
}

Financial tools should be explicitly enabled per use case, not open by default.

Rate limit write operations

{
  "add_recipe": {
    "limits": [
      {
        "counter": "add_recipe_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "anniversaries": {
    "limits": [
      {
        "counter": "anniversaries_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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