Estimate SageMaker notebook job compute cost from static or configured prices.
AI agents call estimate_notebook_job_cost 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 is a read-only operation that queries pricing data and performs calculations to project costs. It has no side effects on AWS infrastructure, does not execute notebooks or code, does not create or modify resources, and does not commit any financial transactions. The output is informational only, used for planning and decision-making prior to actual resource provisioning.
From the tool's definition Tool performs cost estimation only: 'Estimate SageMaker notebook job compute cost from static or configured prices.' It retrieves pricing information and performs calculations without executing infrastructure changes, creating resources, or modifying any data.
Attacks that exploit this kind of access
Estimate SageMaker notebook job compute cost from static or configured prices. 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 estimate_notebook_job_cost: 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.
estimate_notebook_job_cost 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 estimate_notebook_job_cost 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 estimate_notebook_job_cost. 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.
estimate_notebook_job_cost 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.
