THE RISK

Low Risk

Why analyzeQueryPerformance needs a policy

This tool performs query analysis and performance inspection on existing CQL queries. Analysis operations retrieve and examine metadata or execution plans without side effects, making this a Read category tool. Severity is low because analysis of query performance cannot damage data, commit financial obligations, or trigger destructive operations—it merely provides diagnostic information.

From the tool's definition Tool name 'analyzeQueryPerformance' and description 'Analyzes the performance characteristics of a CQL query' indicate a read-only operation that examines query metrics without modifying data or executing arbitrary operations.

POLICY

How to control analyzeQueryPerformance

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

policy.json

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

analyzeQueryPerformance 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 AWS ElastiCache MCP Server — 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 analyzeQueryPerformance

What does the analyzeQueryPerformance tool do? +

Analyzes the performance characteristics of a CQL query - args: keyspace, query. It is categorised as a Read tool in the AWS ElastiCache MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on analyzeQueryPerformance? +

Register the AWS ElastiCache MCP Server MCP server in PolicyLayer and add a rule for analyzeQueryPerformance: 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 AWS ElastiCache MCP Server. Nothing to install.

What risk level is analyzeQueryPerformance? +

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

Can I rate-limit analyzeQueryPerformance? +

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

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

analyzeQueryPerformance is provided by the AWS ElastiCache MCP Server MCP server (awslabs.elasticache-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 AWS ElastiCache MCP Server tool call.

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