AWS MCP Server: Integrating Cloud Operations with Model Context Protocol (MCP)

Overview: What is the AWS MCP Server?

The AWS MCP Server is an implementation of the Model Context Protocol (MCP) tailored specifically for Amazon Web Services (AWS) operations, supporting S3 and DynamoDB services. By leveraging MCP, this server enables seamless integration between AI applications and cloud data sources, providing a standardized protocol that simplifies communication and management tasks.

This server ensures that all operations performed through the AWS interface are automatically logged and made accessible via an audit://aws-operations resource endpoint, enhancing transparency and auditability for developers and system administrators. The incorporation of this server allows AI applications like Claude Desktop to interact with cloud resources in a robust and consistent manner, making it easier to perform common tasks such as creating buckets, uploading objects, managing tables, and more.

🚀 Getting Started with Installation

To run the AWS MCP Server locally and begin integrating it with your AI applications, follow these steps:

1. Clone the Repository

git clone https://github.com/[repository-name]

2. Configure AWS Credentials

Set up your AWS credentials either via environment variables or the Default AWS credential chain.

• Environment Variables:

  • AWS_ACCESS_KEY_ID
  • AWS_SECRET_ACCESS_KEY
  • AWS_REGION (defaults to us-east-1)

• Default AWS Credential Chain:

  • Set up with aws configure.

3. Add MCP Server Configuration

Add the following configuration to your claude_desktop_config.json file:

"mcpServers": {
  "mcp-server-aws": {
    "command": "uv",
    "args": [
      "--directory", "/path/to/repo/mcp-server-aws",
      "run", "mcp-server-aws"
    ]
  }
}

4. Install and Open Claude Desktop App

Download the latest version of the Claude Desktop application.

5. Test Operations

Try performing a read/write operation, such as creating an S3 bucket or uploading an object, to confirm that everything is set up correctly. For troubleshooting, use the Debugging tools provided in the MCP documentation.

💡 Key Use Cases in AI Workflows

The AWS MCP Server can be integrated into various AI workflows to provide robust and efficient data handling capabilities:
