WHAT IT DOES

What backup_database does on Ncp

AI agents use backup_database to create or update resources in Ncp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ncp environment.

RISK

Why backup_database is rated Medium

Backup operations create new data artifacts (backup files) and are reversible write actions. While backups are protective in intent, they create/modify data on the system (write category). The severity is high because improper backup creation could lead to storage issues, resource exhaustion, or if the backup process interferes with database operations, could impact availability.

From the tool's definition Tool name 'backup_database' with description 'Create backup of MySQL database' indicates a data creation/write operation that generates a backup artifact.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs backup_database safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ncp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For backup_database, this is the rule to start with:

backup_database Rate-limited

backup_database stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

    "backup_database": {
      "limits": [
        {
          "counter": "backup_database_rate",

          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Ncp, apply this rule, and every backup_database call is checked against it from then on.
