update_hp_cluster
AI agents use update_hp_cluster to create or update resources in Amazon MQ MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Amazon MQ MCP Server environment.
The tool name indicates it updates a cluster (likely an HBase/HP cluster related to message broker infrastructure), which is a reversible modification operation. This falls under Write category. Severity is high because misconfigured clusters can disrupt message queue operations, but it is reversible and not destructive.
From the tool's definition Tool name 'update_hp_cluster' suggests modification of cluster configuration or state; tool is hosted on AmazonMQ MCP Server for provisioning/managing AMQ brokers. Description is empty, limiting confidence.
Attacks that exploit this kind of access
update_hp_cluster. It is categorised as a Write tool in the Amazon MQ MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Amazon MQ MCP Server MCP server in PolicyLayer and add a rule for update_hp_cluster: 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 Amazon MQ MCP Server. Nothing to install.
update_hp_cluster is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
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.
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.
update_hp_cluster is provided by the Amazon MQ MCP Server MCP server (awslabs.amazon-mq-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
