The most dangerous Rockfish MCP Server tools

22 of Rockfish MCP Server's 48 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

How to control Rockfish MCP Server

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

Deny destructive operations
{
  "delete_database": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

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

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

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "discover_schema": {
    "limits": [
      {
        "counter": "discover_schema_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 Rockfish MCP Server — 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.

Questions about Rockfish MCP Server

Can an AI agent delete data through the Rockfish MCP Server MCP server? +

Yes. The Rockfish MCP Server server exposes 4 destructive tools including delete_database, delete_dataset, delete_model. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through Rockfish MCP Server? +

The Rockfish MCP Server server has 11 write tools including create_database, create_dataset, create_project. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Rockfish MCP Server.

How many tools does the Rockfish MCP Server MCP server expose? +

48 tools across 4 categories: Destructive, Execute, Read, Write. 26 are read-only. 22 can modify, create, or delete data.

How do I enforce a policy on Rockfish MCP Server? +

Register the Rockfish MCP Server MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Rockfish MCP Server tool call.

Deterministic rules across all 48 Rockfish MCP Server tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.

Instant setup, no code required.
