gateway_target_list
AI agents call gateway_target_list 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 naming convention 'gateway_target_list' follows the Read pattern (list, get, fetch operations). No language in the name suggests modification, deletion, or execution. However, confidence is moderate (0.6) rather than high because the description is empty, leaving some ambiguity about what specific data is returned and whether there are any side effects.
From the tool's definition Tool name 'gateway_target_list' indicates a list/query operation that retrieves gateway target information. The 'list' suffix strongly suggests data retrieval with no side effects.
Attacks that exploit this kind of access
gateway_target_list. 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 gateway_target_list: 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.
gateway_target_list 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 gateway_target_list 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 gateway_target_list. 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.
gateway_target_list 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.
