GetAHORun
AI agents call GetAHORun 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 'Get*' is a standard AWS pattern for read-only retrieval operations. Without an explicit description, we rely on the conventional meaning of 'Get' in AWS APIs, which retrieves data without modification or deletion. The tool appears to fetch information about an AHO run, consistent with query/read semantics.
From the tool's definition Tool name 'GetAHORun' suggests retrieval of AHO (likely AWS Health Operations) run data. No description provided, but the 'Get' prefix strongly indicates a read operation with no side effects.
Attacks that exploit this kind of access
GetAHORun. 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 GetAHORun: 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.
GetAHORun 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 GetAHORun 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 GetAHORun. 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.
GetAHORun 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.
