cost-comparison
AI agents call cost-comparison 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.
Cost comparison tools in AWS SageMaker typically query and aggregate pricing or billing data for comparison purposes without modifying state or executing operations. However, confidence is moderate due to the empty description—it could theoretically access sensitive billing data (mild read risk) but unlikely to be Execute, Write, or Destructive without explicit language.
From the tool's definition Tool name 'cost-comparison' suggests a retrieval or analysis operation typical of cost analysis tools in AWS SageMaker. Description is empty, limiting direct evidence.
Attacks that exploit this kind of access
cost-comparison. 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 cost-comparison: 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.
cost-comparison 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 cost-comparison 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 cost-comparison. 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.
cost-comparison 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.
