Description

Implemented AWS Resources MCP Server that allows executing Python code with boto3 to query and interact with AWS resources.

Server Details

Motivation and Context

Created this server to address limitations with existing AWS integration options:

  1. AWS Chatbot has restrictive free tier limits (25 queries/month) with expensive paid tiers
  2. Existing aws-mcp implementation had setup challenges, stability issues on macOS, and was built on Node.js
  3. Needed a containerized solution that leverages Python/boto3 for better stability and easier contribution from Python developers
    This implementation provides a clean, stable Docker-based solution that requires minimal setup and supports full boto3 capabilities for interacting with AWS resources.

How Has This Been Tested?

  • I have been using this tool every week with Claude Desktop client for a few month since I created it.
  • Verified complex cloudfront resolutions, permission resolutions, etc.
  • Tested complex queries like retrieving CodePipeline deployment information
  • Validated cross-platform compatibility (Linux/amd64, Linux/arm64, Linux/arm/v7)
  • Tested both authentication methods (direct AWS credentials and AWS profile)
