Explain related AWS/AWS Labs tools and how this prototype differs.
AI agents call explain_existing_aws_options 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 purely retrieves and explains documentation or information about existing AWS tools and compares them to the current prototype. It has no side effects, makes no changes to infrastructure, runs no code, and poses minimal risk. It fits squarely in the Read category (query/fetch operation) with low severity since misuse would only result in unwanted information disclosure, not infrastructure or data damage.
From the tool's definition The tool is described as 'Explain related AWS/AWS Labs tools and how this prototype differs'—it retrieves and presents information about AWS options without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
Explain related AWS/AWS Labs tools and how this prototype differs. 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 explain_existing_aws_options: 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.
explain_existing_aws_options 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 explain_existing_aws_options 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 explain_existing_aws_options. 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.
explain_existing_aws_options 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.
explain_existing_aws_options is one line of AWS Notebook Runner's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
