This MCP server provides precise tools for optimizing AWS S3 multipart uploads. It calculates exact part counts, estimated upload durations, and validates configurations against S3 service limits like the 5 TB object maximum and 10,000 part limit. Use calculate_upload_plan to determine how a file will be partitioned, recommend_optimal_configuration to find the best part size for your bandwidth, and get_lifecycle_and_integrity_policy to generate checksum and lifecycle cleanup settings.

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

calculate_upload_plan

Provides the fundamental breakdown of how a specific file will be partitioned and how long the process will take

get_lifecycle_and_integrity_policy

Generates the necessary configuration for data integrity and automated cleanup of failed uploads

recommend_optimal_configuration

Suggests the best part size and threshold settings based on the provided bandwidth and file size

Calculate an upload plan for a 500 GB file with 100 MB parts, 4 parallel uploads, and 50 Mbps bandwidth.

The upload requires 5,120 parts. The estimated upload time is approximately 23,040 seconds (6.4 hours). The configuration is within S3 limits.

What is the best part size for a 1 TB file on a 100 Mbps connection?

For a 1 TB file with 100 Mbps bandwidth, a suggested part size is 128 MB to balance throughput and retry efficiency, with a recommended multipart threshold of 100 MB.

Generate a policy for aborting incomplete uploads after 7 days using SHA256.

The policy is set to abort incomplete multipart uploads after 7 days using the SHA256 checksum algorithm for data integrity.

The `calculate_upload_plan` tool will automatically check if your part size is at least 5 MB and if the total part count stays within the 10,000 limit, providing validation flags if they are not.
