How do I know if I need the S3 pointer pattern?

You can use the `calculate_payload_strategy` tool. If the payload size exceeds 256 KB, the tool will indicate that the S3 pointer pattern is required.

Can I check if my FIFO queue will exceed limits?

Yes, the `calculate_queue_capacity` tool analyzes throughput and flags if the calculated in-flight messages exceed the 120,000 account-wide limit.

How do I validate my DLQ settings?

Use the `calculate_retention_and_dlq` tool to ensure your retention period and max receive count are within valid AWS bounds.

This MCP server provides deterministic calculations for AWS SQS configurations. Use calculate_payload_strategy to determine if a message requires the S3 pointer pattern based on size. Use calculate_queue_capacity to analyze throughput limits and in-flight message risks for standard or FIFO queues. Use calculate_retention_and_dlq to validate message lifespan and dead-letter queue thresholds.
