Why mysql-query needs a policy

This tool executes arbitrary MySQL queries, which could include SELECT (Read), INSERT/UPDATE (Write), DELETE/DROP (Destructive), or any other SQL statement. Since the tool accepts arbitrary queries and the most severe applicable category must be chosen, and arbitrary SQL execution can be destructive (DROP, DELETE, TRUNCATE), this is classified as Execute with critical severity.

From the tool's definition "Executes a MySQL query" — the tool runs arbitrary SQL against a MySQL database

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

POLICY

How to control mysql-query

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

policy.json

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

mysql-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.

Create a free account and register Make — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about mysql-query

What does the mysql-query tool do? +

Executes a MySQL query and returns structured tabular output. It is categorised as a Execute tool in the Make MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on mysql-query? +

Register the Make MCP server in PolicyLayer and add a rule for mysql-query: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Make. Nothing to install.

What risk level is mysql-query? +

mysql-query is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit mysql-query? +

Yes. Add a rate_limit block to the mysql-query rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block mysql-query completely? +

Set action: deny in the PolicyLayer policy for mysql-query. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides mysql-query? +

mysql-query is provided by the Make MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Make tool call.

Start from Make, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
