Return EC2/SSM/S3 progress, CloudWatch metrics, and current cost estimate.
AI agents call get_ec2_smoke_run_status to retrieve information from AWS Notebook Runner MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves operational status information and cost estimates from existing AWS resources (EC2, SSM, S3, CloudWatch). It performs read-only operations with no side effects, resource modifications, code execution, data deletion, or financial transactions. The blast radius of misuse is minimal—an attacker gains visibility into infrastructure status and costs but cannot alter or destroy resources.
From the tool's definition Tool description states it 'Return[s] EC2/SSM/S3 progress, CloudWatch metrics, and current cost estimate.' The verb 'return' and 'get' (in tool name) indicate pure retrieval of status and metrics with no modification, execution, or deletion of resources.
Attacks that exploit this kind of access
Return EC2/SSM/S3 progress, CloudWatch metrics, and current cost estimate. It is categorised as a Read tool in the AWS Notebook Runner MCP MCP Server, which means it retrieves data without modifying state.
Register the AWS Notebook Runner MCP server in PolicyLayer and add a rule for get_ec2_smoke_run_status: 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 Notebook Runner MCP. Nothing to install.
get_ec2_smoke_run_status 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 get_ec2_smoke_run_status 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 get_ec2_smoke_run_status. 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.
get_ec2_smoke_run_status is provided by the AWS Notebook Runner MCP server (yummytastycode/aws-notebook-runner-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
