WHAT IT DOES

What update_hp_cluster does on AWS IoT SiteWise MCP Server

AI agents use update_hp_cluster to create or update resources in AWS IoT SiteWise MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AWS IoT SiteWise MCP Server environment.

WHY IT NEEDS A POLICY

Why update_hp_cluster needs a policy

The verb 'update' signals a reversible write operation that modifies cluster state. Given the AWS IoT SiteWise context (industrial IoT data processing) and 'hp_cluster' reference (likely high-performance compute infrastructure), this tool can alter cluster settings, scaling, or configuration—affecting data pipeline operations and resource allocation.

From the tool's definition Tool name 'update_hp_cluster' indicates modification of a high-performance cluster configuration. Description is empty, limiting direct textual evidence.

update_hp_cluster is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit update_hp_cluster? +

Yes. Add a rate_limit block to the update_hp_cluster 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.

How do I block update_hp_cluster completely? +

Set action: deny in the PolicyLayer policy for update_hp_cluster. 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.

What MCP server provides update_hp_cluster? +

update_hp_cluster 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.
