describe-cache-engine-versions
AI agents call describe-cache-engine-versions to retrieve information from Amazon SageMaker AI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The describe-* pattern in AWS APIs universally denotes retrieval of resource information without side effects. Despite empty description reducing confidence slightly, the name strongly indicates this queries cache engine version metadata (likely for Amazon ElastiCache), a purely informational operation with no capability to modify, delete, or execute.
From the tool's definition Tool name 'describe-cache-engine-versions' follows AWS API naming convention for read-only describe operations that retrieve metadata about cache engine versions. No action verbs suggesting modification, deletion, or execution are present.
Attacks that exploit this kind of access
describe-cache-engine-versions. It is categorised as a Read tool in the Amazon SageMaker AI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon SageMaker AI MCP Server MCP server in PolicyLayer and add a rule for describe-cache-engine-versions: 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 Amazon SageMaker AI MCP Server. Nothing to install.
describe-cache-engine-versions is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the describe-cache-engine-versions 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.
Set action: deny in the PolicyLayer policy for describe-cache-engine-versions. 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.
describe-cache-engine-versions is provided by the Amazon SageMaker AI MCP Server MCP server (awslabs.sagemaker-ai-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
