MOST DANGEROUS TOOLS

Critical Risk

The most dangerous MCP Chat tools

Financial · High order_pizza Ordering a pizza constitutes a financial commitment: it places a real order that incurs a monetary charge. Write · Low create_story This tool creates new textual content (a story) without modifying existing data or triggering external operations. Write · Medium edit_document The tool modifies document content through string replacement, which is a reversible write operation.

4 of MCP Chat's 8 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control MCP Chat

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

Block financial tools by default

{
  "order_pizza": {
    "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

{
  "create_story": {
    "limits": [
      {
        "counter": "create_story_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "analyze_project": {
    "limits": [
      {
        "counter": "analyze_project_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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