WHAT IT DOES

What optimize_sql does on Metabase MCP

AI agents call optimize_sql to retrieve information from Metabase MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why optimize_sql is rated Low

This tool retrieves optimization suggestions for SQL queries—a read-only operation that analyzes query structure without executing or modifying any data. It has no blast radius; misuse would only produce irrelevant optimization suggestions without operational impact.

From the tool's definition Tool name 'optimize_sql' and description 'Get suggestions to optimize a SQL query' indicate analysis and recommendations only, with no execution of queries, modification of data, or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs optimize_sql safely

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

optimize_sql Allowed

optimize_sql is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "optimize_sql": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about optimize_sql

What does the optimize_sql tool do? +

Get suggestions to optimize a SQL query. It is categorised as a Read tool in the Metabase MCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on optimize_sql? +

Register the Metabase MCP server in PolicyLayer and add a rule for optimize_sql: 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 Metabase MCP. Nothing to install.

What risk level is optimize_sql? +

optimize_sql is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit optimize_sql? +

Yes. Add a rate_limit block to the optimize_sql 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_sql completely? +

Set action: deny in the PolicyLayer policy for optimize_sql. 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_sql? +

optimize_sql is provided by the Metabase MCP server (1luvc0d3/metabase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
