The most dangerous Cross Validated Search tools

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

How to control Cross Validated Search

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

Deny destructive operations
{
  "clear_cache": {
    "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
{
  "llm_context": {
    "limits": [
      {
        "counter": "llm_context_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

  1. Create a free account and register Cross Validated Search — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
