ListAHOBatches
AI agents call ListAHOBatches 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 tool name suggests it retrieves or enumerates batches without side effects. Although the description is empty, the 'List' prefix and presence among sibling tools like 'ActivateAHOReadSets' and other query-like operations support a Read classification. Confidence is lowered due to the empty description, but blast radius is minimal since listing operations typically expose only metadata.
From the tool's definition Tool name 'ListAHOBatches' indicates a listing operation. The 'List' prefix is a standard AWS convention for read-only retrieval of resource metadata or collections without modification.
Attacks that exploit this kind of access
ListAHOBatches. 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 ListAHOBatches: 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.
ListAHOBatches 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 ListAHOBatches 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 ListAHOBatches. 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.
ListAHOBatches 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.
