get_user_policy
AI agents call get_user_policy 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 strongly suggests this tool retrieves or queries user policy data without modifying it. Without a description, confidence is moderately reduced, but the naming convention and context of similar tools on the AWS IoT SiteWise MCP server indicate a read-only retrieval operation. The potential blast radius is low since policy retrieval alone does not enable data modification, deletion, or financial transactions.
From the tool's definition Tool name 'get_user_policy' indicates retrieval of policy information. The description is empty, but the 'get_' prefix is consistently associated with read operations across the sibling tools on this server (which include aggregation, analysis, and…

get_user_policy. 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_user_policy: 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_user_policy 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_user_policy 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_user_policy. 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_user_policy 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.
