policy_generation_list
AI agents call policy_generation_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 name pattern '*_list' strongly indicates data retrieval without side effects. However, the empty description creates ambiguity about whether this tool might read sensitive policy data or perform more complex operations. Given only the naming convention and the absence of contrary evidence, Read is the most probable classification, but confidence is moderate due to lack of descriptive detail.
From the tool's definition Tool name 'policy_generation_list' suggests a listing or querying operation, consistent with the Read category. The empty description provides minimal concrete evidence of its function.
Attacks that exploit this kind of access
policy_generation_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 policy_generation_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.
policy_generation_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 policy_generation_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 policy_generation_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.
policy_generation_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.
