MOST DANGEROUS TOOLS

Critical Risk

The most dangerous USQL MCP Server tools

Destructive · High cancel_job Cancelling a running job and stopping its underlying query execution is an irreversible action — the job's progress is lost and cannot be resumed. Execute · Critical execute_query SQL query execution is Execute category because it runs arbitrary code whose effects depend entirely on the query argument—an agent could execute DELETE, DROP, UPDATE, or other destructive commands without explicit user Execute · High execute_script This tool executes arbitrary SQL scripts with potentially unrestricted effects.

3 of USQL MCP Server's 8 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control USQL MCP Server

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

Deny destructive operations

{
  "cancel_job": {
    "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

{
  "describe_table": {
    "limits": [
      {
        "counter": "describe_table_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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