mysql_optimize_table

THE RISK

High Risk

OPTIMIZE TABLE in MySQL is a maintenance operation that restructures the table, reclaims unused space, and defragments data/index pages. It is not a simple read, and while generally non-destructive, it executes a significant server-side operation that rewrites the table, acquires locks, and can affect performance.

HOW TO CONTROL MYSQL_OPTIMIZE_TABLE

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "mysql_optimize_table": {
      "limits": [
        {
          "counter": "mysql_optimize_table_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

mysql_optimize_table 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 Mcp Windows — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

What does the mysql_optimize_table tool do? +

Optimize a table to reclaim unused space and defragment. It is categorised as a Execute tool in the Mcp Windows 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_optimize_table? +

Register the Mcp Windows MCP server in PolicyLayer and add a rule for mysql_optimize_table: 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 Mcp Windows. Nothing to install.

What risk level is mysql_optimize_table? +

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

Can I rate-limit mysql_optimize_table? +

Yes. Add a rate_limit block to the mysql_optimize_table 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_optimize_table completely? +

Set action: deny in the PolicyLayer policy for mysql_optimize_table. 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_optimize_table? +

mysql_optimize_table is provided by the Mcp Windows MCP server (mukul975/mcp-windows-automation). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Mcp Windows tool call.
