Part of the Amazon MQ MCP Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents use create_broker to create or modify resources in Amazon MQ MCP Server. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

Without a policy, an AI agent could call create_broker repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Amazon MQ MCP Server.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the create_broker tool do? +

Create a ActiveMQ or RabbitMQ broker on AmazonMQ. Args: region: AWS region code (e.g., 'us-east-1', 'eu-west-1'). broker_name: The name given to the broker. engine_type: The engine type of the broker. Possible values: "RABBITMQ" and "ACTIVEMQ". deployment_mode: The broker deployment mode. Possible values for ACTIVEMQ engine type: SINGLE_INSTANCE, ACTIVE_STANDBY_MULTI_AZ and possible values for RABBITMQ engine type: SINGLE_INSTANCE, CLUSTER_MULTI_AZ. username: The username to access the broker. password: The password for the user. engine_version: The broker engine version. Defaults to the latest available version for the specified broker engine type. It should also be unspecified to use the latest version. publicly_accessible: Enables connections from applications outside of the VPC that hosts the broker's subnets. Default to True for publicly accessible broker. host_instance_type: The broker instance type. Default to production-ready instance type "mq.m5.xlarge". auto_minor_version_upgrade: Whether or not to enable minor version automatic upgrade. Default is true. Returns: Response from API. 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.

How do I enforce a policy on create_broker? +

Add a rule in your Intercept YAML policy under the tools section for create_broker. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Amazon MQ MCP Server MCP server.

What risk level is create_broker? +

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

Can I rate-limit create_broker? +

Yes. Add a rate_limit block to the create_broker rule in your Intercept 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 create_broker completely? +

Set action: deny in the Intercept policy for create_broker. 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 create_broker? +

create_broker is provided by the Amazon MQ MCP Server MCP server (awslabs.amazon-mq-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
