analyzeQueryPerformance

WHAT IT DOES

What analyzeQueryPerformance does on AWS Labs Amazon Kendra Index MCP Server

AI agents call analyzeQueryPerformance to retrieve information from AWS Labs Amazon Kendra Index MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why analyzeQueryPerformance needs a policy

This is a read-only operation that examines query performance metrics. It retrieves or analyzes information about a query's execution characteristics without creating, modifying, deleting, or executing any data-altering operations. The tool does not execute the query itself (which would be Execute), but rather performs analysis on query structure and performance, making it a Read operation.

From the tool's definition Tool description states it 'Analyzes the performance characteristics of a CQL query' with arguments for keyspace and query. The verb 'analyzes' combined with 'performance characteristics' indicates inspection/measurement of existing data without modification.

POLICY

How to control analyzeQueryPerformance

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS Labs Amazon Kendra Index 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.
