get_query_results
AI agents call get_query_results to retrieve information from AWS IoT SiteWise MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get' prefix combined with 'query_results' indicates data retrieval. No write, execute, delete, or financial keywords present. Even in the context of AWS IoT SiteWise (a time-series data platform), retrieving query results is a read-only operation with minimal blast radius if misused by an AI agent—it can only expose data already accessible to the service credentials, not modify infrastructure or trigger…
From the tool's definition Tool name 'get_query_results' indicates retrieval of previously computed query results with no side effects. Empty description is uninformative, but the name strongly suggests a Read operation typical of AWS query/analytics services.
Attacks that exploit this kind of access
get_query_results. It is categorised as a Read tool in the AWS IoT SiteWise MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AWS IoT SiteWise MCP Server MCP server in PolicyLayer and add a rule for get_query_results: 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 IoT SiteWise MCP Server. Nothing to install.
get_query_results 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_query_results 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_query_results. 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_query_results is provided by the AWS IoT SiteWise MCP Server MCP server (awslabs.aws-iot-sitewise-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
