Returns a list of Timestream for InfluxDB DB instances filtered by status (case-insensitive).
AI agents call LsInstancesByStatus 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.
This tool queries and retrieves information about Timestream for InfluxDB instances based on status filtering. It has no side effects, does not modify data, execute commands, or trigger external operations. It is a straightforward read-only query operation that matches the 'Read' category definition of retrieving or querying data without side effects.
From the tool's definition Tool name 'LsInstancesByStatus' uses 'Ls' prefix (list) and description states 'Returns a list... filtered by status' - purely retrieval operation with no modification or execution capabilities.
Attacks that exploit this kind of access
Returns a list of Timestream for InfluxDB DB instances filtered by status (case-insensitive). 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 LsInstancesByStatus: 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.
LsInstancesByStatus 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 LsInstancesByStatus 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 LsInstancesByStatus. 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.
LsInstancesByStatus 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.
