MOST DANGEROUS TOOLS

High Risk
Write · Medium add_comment The tool creates new data (comments) attached to reports, which is a reversible modification operation. Write · Medium close_report Closing a report is a reversible write operation that changes the state of a security report. Write · Medium submit_report This tool creates new data (a vulnerability report) in the HackerOne system, which is a Write operation.

3 of HackerOne MCP Server's 16 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

HOW TO CONTROL HACKERONE MCP SERVER

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

Rate limit write operations
{
  "add_comment": {
    "limits": [
      {
        "counter": "add_comment_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "analyze_report_patterns": {
    "limits": [
      {
        "counter": "analyze_report_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.
