Why analyze_index_usage needs a policy

This tool retrieves and analyzes statistics about how indexes are being used. It performs a query operation with no side effects—no data is created, modified, deleted, or code executed. The server description emphasizes 'read-only queries' and 'monitoring,' and this tool fits that profile.

From the tool's definition Tool name 'analyze_index_usage' and description 'Analyze index usage statistics' indicate a read-only operation that queries and reports on existing index performance data without modifying any database structures or data.

POLICY

How to control analyze_index_usage

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

policy.json

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

analyze_index_usage is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Mysql — 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 analyze_index_usage

What does the analyze_index_usage tool do? +

Analyze index usage statistics. It is categorised as a Read tool in the Mysql MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on analyze_index_usage? +

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

What risk level is analyze_index_usage? +

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

Can I rate-limit analyze_index_usage? +

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

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

analyze_index_usage is provided by the Mysql MCP server (mukul975/mysql-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Mysql tool call.

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