What is the Amazon S3 MCP Server?
Connect your Amazon S3 environment to your AI agent to unlock professional cloud storage orchestration. From creating and auditing buckets to managing individual objects and their metadata, your agent handles your AWS data storage through natural conversation.
What you can do
- Bucket Orchestration — List your S3 buckets, create new ones, and retrieve their location or policy configurations
- Object Management — List objects within a specific bucket, including their size and last modified timestamps
- Data Ingestion — Upload objects directly to S3 or delete unwanted files to maintain your storage hygiene
- Metadata Auditing — Retrieve technical metadata (headers, content type, size) for specific objects without downloading them
- Security Oversight — Audit bucket ACLs and policies to ensure your cloud storage meets compliance requirements
How it works
- Subscribe to this server
- Enter your AWS Access Key, Secret Key, and Region
- Start managing your cloud storage and monitoring your data assets through Claude, Cursor, or any MCP-compatible client
Who is this for?
- Cloud Engineers — automate bucket audits and verify object configurations effortlessly
- Data Scientists — quickly find specific datasets or list objects in your data lake directly from chat
- DevOps Specialists — monitor S3 policies and manage file cleanups using simple commands
- Security Analysts — audit bucket access controls and identify exposed data via API queries

Frequently asked questions
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.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
