Retrieves detailed information about a specific EC2 instance.
AI agents call get_instance_details to retrieve information from AWS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries EC2 instance metadata and configuration without creating, modifying, deleting, or executing any infrastructure changes. It is a pure data retrieval operation with no side effects. The read-only nature of the server and the 'get_' naming pattern confirm this classification.
From the tool's definition Tool name contains 'get_' and description states it 'Retrieves detailed information' with no mention of modification, deletion, or side effects. Server is explicitly described as 'read-only'.
Attacks that exploit this kind of access
Retrieves detailed information about a specific EC2 instance. It is categorised as a Read tool in the AWS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AWS MCP Server MCP server in PolicyLayer and add a rule for get_instance_details: 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 MCP Server. Nothing to install.
get_instance_details 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_instance_details 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_instance_details. 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_instance_details is provided by the AWS MCP Server MCP server (sergiosediq/aws-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_instance_details is one line of AWS MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
