The most dangerous MCP Interface Validator tools

5 of MCP Interface Validator's 13 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

How to control MCP Interface Validator

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

Rate limit write operations
{
  "activate-constraints": {
    "limits": [
      {
        "counter": "activate-constraints_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "analyze_code_patterns": {
    "limits": [
      {
        "counter": "analyze_code_patterns_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

  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.
