MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Codex Bridge tools

Destructive · Medium codex_reset The tool irreversibly clears conversation history and statistics. Execute · Medium codex_ask This tool sends a request to an external LLM service (GPT Codex), executing an external operation.

2 of Codex Bridge's 9 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Codex Bridge

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

Deny destructive operations

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

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

Cap read operations

{
  "codex_debug": {
    "limits": [
      {
        "counter": "codex_debug_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
