A list of tags applied to the resource.
AI agents call ListTagsForResource 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.
This tool queries and returns tag information associated with an AWS resource. It performs a read-only operation with no side effects—it does not create, modify, delete, or execute anything. The blast radius of misuse is minimal, as an attacker could only discover metadata about resource organization/classification, which does not compromise confidentiality of sensitive data or enable further attacks directly.
From the tool's definition Tool name 'ListTagsForResource' and description 'A list of tags applied to the resource' indicate a retrieval operation that returns metadata about resource tags without modification, deletion, or external execution.
Attacks that exploit this kind of access
A list of tags applied to the resource. 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 ListTagsForResource: 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.
ListTagsForResource 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 ListTagsForResource 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 ListTagsForResource. 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.
ListTagsForResource 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.
