Demo: Fix Dynamodb Permission Error

I tried AWS Chatbot with Developer Access. Free Tier has a limit of 25 query/month for resources. Next tier is $19/month include 90% of the features I don't use. And the results are in a fashion of JSON and a lot of restrictions.

I tried using aws-mcp but ran into a few issues:

1. Setup Hassle: Had to clone a git repo and deal with local setup
2. Stability Issues: Wasn't stable enough on my Mac
3. Node.js Stack: As a Python developer, I couldn't effectively contribute back to the Node.js codebase

So I created this new approach that:

• Runs directly from a Docker image - no git clone needed
• Uses Python and boto3 for better stability
• Makes it easy for Python folks to contribute
• Includes proper sandboxing for code execution
• Keeps everything containerized and clean

For more information about the Model Context Protocol and how it works, see Anthropic's MCP documentation.

The server exposes the following resource:

• aws://query_resources: A dynamic resource that provides access to AWS resources through boto3 queries

Here are some example queries you can execute:

1. List S3 buckets:

s3 = session.client('s3')
result = s3.list_buckets()

2. Get latest CodePipeline deployment:

def get_latest_deployment(pipeline_name):
    codepipeline = session.client('codepipeline')

    result = codepipeline.list_pipeline_executions(
        pipelineName=pipeline_name,
        maxResults=5
    )

    if result['pipelineExecutionSummaries']:
        latest_execution = max(
            [e for e in result['pipelineExecutionSummaries']
             if e['status'] == 'Succeeded'],
            key=itemgetter('startTime'),
            default=None
        )

        if latest_execution:
            result = codepipeline.get_pipeline_execution(
                pipelineName=pipeline_name,
                pipelineExecutionId=latest_execution['pipelineExecutionId']
            )
        else:
            result = None
    else:
        result = None

    return result

result = get_latest_deployment("your-pipeline-name")

Note: All code snippets must set a result variable that will be returned to the client. The result variable will be automatically converted to JSON format, with proper handling of AWS-specific objects and datetime values.

The server offers a tool for executing AWS queries:

• aws_resources_query_or_modify
  • Execute a boto3 code snippet to query or modify AWS resources
  • Input:
    • code_snippet (string): Python code using boto3 to query AWS resources
    • The code must set a result variable with the query output
  • Allowed imports:
    • boto3
    • operator
    • json
    • datetime
    • pytz
    • dateutil
    • re
    • time
  • Available built-in functions:
    • Basic types: dict, list, tuple, set, str, int, float, bool
    • Operations: len, max, min, sorted, filter, map, sum, any, all
    • Object handling: hasattr, getattr, isinstance
    • Other: print, import

The server includes several safety features:

• AST-based code analysis to validate imports and code structure
• Restricted execution environment with limited built-in functions
• JSON serialization of results with proper handling of AWS-specific objects
• Proper error handling and reporting

You'll need AWS credentials with appropriate permissions to query AWS resources. You can obtain these by:

1. Creating an IAM user in your AWS account
2. Generating access keys for programmatic access
3. Ensuring the IAM user has necessary permissions for the AWS services you want to query

The following environment variables are required:

• AWS_ACCESS_KEY_ID: Your AWS access key
• AWS_SECRET_ACCESS_KEY: Your AWS secret key
• AWS_SESSION_TOKEN: (Optional) AWS session token if using temporary credentials
• AWS_DEFAULT_REGION: AWS region (defaults to 'us-east-1' if not set)

You can also use a profile stored in the ~/.aws/credentials file. To do this, set the AWS_PROFILE environment variable to the profile name.

Note: Keep your AWS credentials secure and never commit them to version control.

To install AWS Resources MCP Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install mcp-server-aws-resources-python --client claude

You can either build the image locally or pull it from Docker Hub. The image is built for the Linux platform.

• Linux/amd64
• Linux/arm64
• Linux/arm/v7

docker pull buryhuang/mcp-server-aws-resources:latest

docker build -t mcp-server-aws-resources .

Run the container:

docker run \
  -e AWS_ACCESS_KEY_ID=your_access_key_id_here \
  -e AWS_SECRET_ACCESS_KEY=your_secret_access_key_here \
  -e AWS_DEFAULT_REGION=your_AWS_DEFAULT_REGION \
  buryhuang/mcp-server-aws-resources:latest

Or using stored credentials and a profile:

docker run \
  -e AWS_PROFILE=[AWS_PROFILE_NAME] \
  -v ~/.aws:/root/.aws \
  buryhuang/mcp-server-aws-resources:latest

To publish the Docker image for multiple platforms, you can use the docker buildx command. Follow these steps:

1. Create a new builder instance (if you haven't already):

   docker buildx create --use

2. Build and push the image for multiple platforms:

   docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v7 -t buryhuang/mcp-server-aws-resources:latest --push .

3. Verify the image is available for the specified platforms:

   docker buildx imagetools inspect buryhuang/mcp-server-aws-resources:latest
