This MCP server provides precise sizing calculations for AWS Managed Streaming for Apache Kafka (MSK) clusters. It uses deterministic logic to determine the required partition count per broker based on a 100 MB/s throughput threshold, calculates total storage needs across the retention period, and validates hardware constraints for specific AWS instance types. Use calculate_partition_and_storage_needs to find foundational scaling requirements, evaluate_broker_capacity to check if your partition count fits within the limits of instances like kafka.m5.large or kafka.m5.4xlarge, and calculate_network_and_limits to verify network throughput and cluster-wide architectural ceilings.

3 tools expose this connector's capabilities to your AI agent.

calculate_network_and_limits

Analyzes network throughput requirements and validates cluster-wide architectural limits

calculate_partition_and_storage_needs

Determines foundational scaling requirements (partitions and storage) based on throughput and time

evaluate_broker_capacity

Checks if the proposed partition count is physically supported by the chosen AWS MSK instance types

I have a message rate of 500 messages per second, each 10 KB, with a 7-day retention and 3 brokers. How many partitions and how much storage do I need?

You will need 1 partition per broker (total 3 partitions) and approximately 2.86 GB of storage per broker.

Will a kafka.m5.large instance support 5000 partitions per broker?

No, a kafka.m5.large instance is limited to a maximum of 4,000 partitions per broker.

Calculate the network requirements for 10,000 messages/sec at 50 KB each with 4 brokers.

The network throughput per broker is 1.0 Gbps.

The tool calculates the partition count per broker by dividing the required message rate by the 100 MB/s throughput threshold per partition.
