POLICY

How to control Online Judge MCP Server

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

Cap read operations

{
  "get_problem_details": {
    "limits": [
      {
        "counter": "get_problem_details_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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