## Description

This Amazon S3 MCP lets you manage your AWS cloud storage through your AI agent. Managing storage usually means jumping between the console and your terminal to keep track of bucket permissions and file sizes. This tool changes that by letting your agent handle the heavy lifting. Instead of clicking through pages to find a specific dataset or checking if a bucket is public, you just ask your agent. You can have it list every bucket in your account, create new ones for specific projects, or grab the metadata for a file to see its headers and size. If you need to move data, your agent can upload objects directly to the cloud or clear out old files to keep your storage costs down. It handles the technical details of S3 while you stay focused on the actual data. You'll find this is a huge time saver when you're browsing the Vinkius catalog for high-level infrastructure tools. It's about getting your cloud storage organized through natural conversation rather than manual API calls or complex CLI commands.

## Tools

### delete_bucket
Remove an S3 bucket from your account. This is useful for cleaning up old infrastructure or decommissioned projects.

### list_objects
List files within a specific bucket, including filtering by prefix. It's the fastest way to find specific assets in a large folder.

### get_object_metadata
Get headers, content types, and sizes for objects. This lets you inspect files without having to download them first.

### get_object_data
Retrieve the actual content of an S3 object. Use this when your agent needs to read the file data directly.

### put_object
Upload a file or object to your S3 storage. This lets your agent move data into the cloud for you.

### delete_object
Delete a specific object from a bucket. Use this to remove unwanted files or manage storage hygiene.

### get_bucket_policy
Retrieve the JSON policy for a bucket. This is essential for checking who has access to your data.

### get_bucket_acl
Get the Access Control List for a bucket. Use this to verify specific permissions for users and groups.

### list_buckets
See every S3 bucket in your AWS account. This helps you get a quick overview of your current storage structure.

### create_bucket
Create a new S3 bucket instantly. Use this to set up new storage areas for projects or applications.

## Prompt Examples

**Prompt:** 
```
Can you check if my 'prod-data' bucket is publicly accessible?
```

**Response:** 
```
I've retrieved the policy for 'prod-data'. It currently has a public read policy attached (`s3:GetObject` allowed for `*`). You should probably restrict this to avoid exposing your data to the public.
```

**Prompt:** 
```
List the files in the 'logs' bucket that start with 'error-2024'.
```

**Response:** 
```
I found 15 files in the 'logs' bucket starting with 'error-2024'. Here are the top 5:

* error-2024-01-01.log (1.2MB)
* error-2024-01-02.log (450KB)
* error-2024-01-03.log (2.1MB)
* error-2024-01-04.log (890KB)
* error-2024-01-05.log (1.1MB)
```

**Prompt:** 
```
What's the size of the 'backup.zip' file in the 'backups' bucket?
```

**Response:** 
```
I checked the metadata for 'backup.zip' in the 'backups' bucket. The file size is 4.2 GB and the content type is `application/zip`. It was last modified on July 10, 2026.
```

## Capabilities

### Create new storage buckets
Create new storage buckets for your AWS account instantly.

### Upload files directly to S3
Upload files directly to S3 storage using natural language.

### Audit bucket security policies
Audit bucket security policies to ensure your data stays private.

### List files with specific prefixes
List files within a bucket using prefixes to find specific assets.

### Retrieve object metadata
Retrieve object metadata to see file sizes and headers without downloads.

### Delete old storage objects
Delete old storage objects to maintain a clean and cost-effective environment.

## Use Cases

### Auditing permissions
A security analyst finds a bucket with a weird policy. They ask the agent to use get_bucket_policy to see if it's public and then report the findings.

### Data discovery
A data scientist needs a specific CSV from 2024. They ask the agent to list_objects with a prefix to find the exact path.

### Infrastructure cleanup
A DevOps lead wants to delete old test buckets. They ask the agent to list_buckets, identify the old ones, and then delete_bucket for each.

### Rapid deployment
A developer needs a new bucket for a production app. They ask the agent to create_bucket with the correct naming convention immediately.

## Benefits

- Stop clicking through the AWS console by using list_buckets to see your entire storage layout in one chat.
- Secure your data faster by using get_bucket_policy to check for public access and ensure compliance.
- Keep your storage costs low by using delete_object to prune old files and maintain a clean environment.
- Find specific datasets instantly with list_objects using prefixes, which saves time for data scientists.
- Inspect file details without downloading them by using get_object_metadata to see headers and sizes.
- Automate data ingestion by using put_object to move files into your cloud storage via simple commands.

## How It Works

The bottom line is you get full control over your AWS S3 storage using plain English commands.

1. Connect your AWS credentials to the Connector in your client.
2. Provide the specific region and access keys.
3. Ask your agent to perform actions like listing buckets or checking policies.

## Frequently Asked Questions

**Can the Amazon S3 MCP create new buckets for me?**
Yes, you can ask your agent to create new buckets directly. It will handle the naming and setup based on your instructions, so you don't have to manually configure them in the AWS console.

**How do I use the Amazon S3 MCP to check my security settings?**
You can ask your agent to retrieve the bucket policy or ACL for any specific bucket. It will show you exactly who has access, helping you spot any security gaps instantly.

**Can I use the Amazon S3 MCP to move files into my cloud storage?**
Yes, your agent can upload objects directly to S3 using the put_object tool. You just tell it what to upload and where it should go, and it handles the rest.

**Will the Amazon S3 MCP help me save money on my AWS bill?**
It can help by making it easier to identify and delete old or unnecessary files. You can ask your agent to list objects and then delete the ones you no longer need to keep your storage costs down.

**Does the Amazon S3 MCP work with Claude and Cursor?**
Yes, this Connector is designed to work with any MCP-compatible client, including Claude, Cursor, and Windsurf. Once connected, you can manage your S3 storage directly from those apps.

**Can I see the file size of my S3 objects without downloading them?**
Yes, the Connector can retrieve object metadata. This means your agent can tell you the file size, content type, and other details without actually downloading the full file.

**How do I get my AWS Access Key and Secret Key?**
Log in to the AWS Management Console, navigate to IAM (Identity and Access Management), and create a user with programmatic access. Ensure this user has S3 permissions (e.g., `AmazonS3FullAccess`). You will receive an Access Key ID and a Secret Access Key.

**Can I upload large files using this integration?**
The `put_object` tool handles standard REST uploads and is best suited for small to medium-sized files or JSON data. For very large files, standard AWS tools utilizing Multipart Uploads are recommended.

**How do I ensure my buckets are secure?**
You can use the `get_bucket_policy` and `get_bucket_acl` tools to audit the current access controls applied to any of your buckets directly from the chat.
