KendraQueryTool · Amazon Redshift MCP Server MCP

WHAT IT DOES

What KendraQueryTool does on Amazon Redshift MCP Server

AI agents call KendraQueryTool to retrieve information from Amazon Redshift 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 KendraQueryTool needs a policy

Query tools retrieve and search data without side effects, placing this in the Read category. Severity is elevated to high because Kendra can index sensitive enterprise documents, and unrestricted queries could expose confidential information to an AI agent. Confidence is moderate (0.75) due to the empty description and reliance on naming convention alone.

From the tool's definition Tool name 'KendraQueryTool' indicates a query operation on Amazon Kendra (AWS search service). The absence of descriptive text limits certainty, but 'Query' typically denotes retrieval of search results without modification.

Documented attack patterns abuse exactly the kind of access KendraQueryTool gives an agent:

POLICY

How to control KendraQueryTool

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

policy.json

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

KendraQueryTool 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 Amazon Redshift 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.
