optimize_table · MCP MySQL Server MCP: Risk & Policy

WHAT IT DOES

What optimize_table does on MCP MySQL Server

AI agents invoke optimize_table to trigger actions in MCP MySQL 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 IT NEEDS A POLICY

Why optimize_table needs a policy

Optimizing a table involves executing a MySQL OPTIMIZE TABLE command which rebuilds indexes and updates table statistics. This is an active operation that modifies internal table structures and index data, but does not delete user data or move money.

Verdict

optimize_table Rate-limited

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.

FAQ

Questions about optimize_table

What does the optimize_table tool do? +

Optimize a table for better performance by rebuilding indexes and updating statistics. It is categorised as a Execute tool in the MCP MySQL Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on optimize_table? +

Register the MCP MySQL Server MCP server in PolicyLayer and add a rule for 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 MySQL Server. Nothing to install.

What risk level is optimize_table? +

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

Can I rate-limit optimize_table? +

Yes. Add a rate_limit block to the 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 optimize_table completely? +

Set action: deny in the PolicyLayer policy for 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 optimize_table? +

optimize_table is provided by the MCP MySQL Server MCP server (kami2k1/mcp-mysql). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
