Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

AWS S3 MCP Server

A Model Context Protocol (MCP) server that gives AI assistants (Claude, Cursor, etc.) direct access to AWS S3 — enabling them to list, upload, download, and manage S3 buckets and objects through natural language.

Why This Exists

When building AI agent pipelines, you often need agents to read from or write to S3 — whether that's fetching documents for RAG, persisting outputs, or managing files dynamically. This MCP server bridges that gap by exposing S3 operations as MCP tools, so any MCP-compatible AI client can interact with S3 without custom integration work.

Prerequisites

Node.js 18+
AWS account with S3 access
AWS credentials (Access Key ID + Secret, or IAM role)
An MCP-compatible client (Claude Desktop, Cursor, etc.)

Quick Start

1. Install via npx (no installation needed)

{
  "mcpServers": {
    "aws-s3": {
      "command": "npx",
      "args": ["@gangadharrr/aws-s3"],
      "env": {
        "AWS_REGION": "us-east-1",
        "AWS_ACCESS_KEY_ID": "your-access-key-id",
        "AWS_SECRET_ACCESS_KEY": "your-secret-access-key"
      },
      "autoApprove": ["list_buckets", "list_objects", "get_bucket_policy"]
    }
  }
}

Add this to your MCP client config file:

Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json
Cursor: .cursor/mcp.json in your project root

2. Using AWS CLI credentials (recommended for local dev)

If you've already configured the AWS CLI (aws configure), you can omit the key env vars:

{
  "mcpServers": {
    "aws-s3": {
      "command": "npx",
      "args": ["@gangadharrr/aws-s3"],
      "env": {
        "AWS_REGION": "us-east-1"
      }
    }
  }
}

Parameters for set_bucket_policy: | Name | Type | Required | Description | |------|------|----------|-------------| | bucketName | string | ✅ | Target bucket | | policy | string/object | ✅ | Policy document (JSON string or object) |

AWS Authentication

The server uses the AWS SDK credential resolution chain in this order:

Environment variables — AWS_ACCESS_KEY_ID + AWS_SECRET_ACCESS_KEY
Shared credentials file — ~/.aws/credentials (configured via aws configure)
EC2 Instance Metadata — if running on an EC2 instance with an IAM role

For production, IAM roles are recommended over static credentials.
