WHAT IT DOES

What db-query does on Magento 2 Development MCP Server

AI agents invoke db-query to trigger actions in Magento 2 Development MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

Why db-query needs a policy

This tool executes arbitrary SQL against the production/development database. It can run SELECT (Read), INSERT/UPDATE (Write), DELETE/DROP (Destructive), or any other SQL. Since the tool permits arbitrary SQL with no stated restrictions, it must be classified at the most severe applicable level.

From the tool's definition "Execute SQL queries directly on Magento 2 database"

Documented attack patterns abuse exactly the kind of access db-query gives an agent:

POLICY

How to control db-query

PolicyLayer is an MCP gateway — it sits between your AI agents and Magento 2 Development MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for db-query:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "db-query": {
      "limits": [
        {
          "counter": "db-query_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

db-query stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
