What is the Amazon S3 Bucket MCP Server?
Grant your AI agent precise, scoped access to a single Amazon S3 bucket — no more, no less. Unlike full S3 access, this integration enforces the principle of least privilege: your agent can read, write, and manage objects exclusively within one pre-configured bucket.
What you can do
- Browse Objects — List and navigate files within the bucket using prefix and delimiter filters
- Read Data — Retrieve object contents or inspect metadata (headers, content type, size) without downloading
- Write Data — Upload string or JSON content as objects directly into the bucket
- Clean Up — Delete specific objects to maintain storage hygiene
- Audit Security — Inspect the bucket's access policy and ACL to ensure compliance
How it works
- Subscribe to this server
- Enter your AWS Access Key, Secret Key, Region, and the target Bucket Name
- Your agent operates exclusively within that bucket — no access to other buckets or account-level operations
Why single-bucket?
AI agents should follow the principle of least privilege. Granting full S3 access to an autonomous agent creates unnecessary blast radius. This server confines the agent to a single bucket, which means:
- No accidental bucket creation or deletion
- No cross-bucket data exposure
- Clearer audit trail for compliance
- Safer agent-to-agent delegation
Who is this for?
- AI Engineers — give each agent a dedicated data workspace without exposing your entire cloud storage
- Data Teams — let agents process, query, and write results to a specific data lake partition
- Platform Engineers — enforce tenant isolation by assigning one bucket per agent or workflow
- Security-Conscious Teams — minimize attack surface by scoping storage access to exactly what's needed

Why VS Code Copilot?
GitHub Copilot Agent mode brings Amazon S3 Bucket data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 7 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.
- —
VS Code is used by over 70% of developers. adding MCP tools to Copilot means your team can leverage external data without leaving their primary editor
- —
Project-scoped MCP configs (
.vscode/mcp.json) let you commit server configurations to your repository, ensuring the entire team shares the same tool access - —
Copilot's Agent mode integrates MCP tools seamlessly with file editing, terminal commands, and workspace search in a single agentic loop
- —
GitHub's enterprise compliance and audit features extend to MCP tool usage, providing visibility into how AI interacts with external services

Frequently asked questions
How is this different from the full Amazon S3 server?
The full Amazon S3 server gives the agent access to all buckets in your AWS account — it can list, create, and delete buckets. This server scopes the agent to a single, pre-configured bucket. The agent can only read, write, and manage objects within that bucket. This follows the principle of least privilege, which is critical for secure agent deployments.
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. For this integration, we recommend a policy scoped to a single bucket (e.g., s3:GetObject, s3:PutObject, s3:DeleteObject, s3:ListBucket limited to your target bucket ARN).
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.
Can my agent access multiple buckets?
Each instance of this server is scoped to exactly one bucket. If your agent needs access to multiple buckets, you can subscribe to this server multiple times — each with a different bucket configuration. This maintains strict isolation between data boundaries.
Which VS Code version supports MCP?
MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.
How do I switch to Agent mode?
Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.
Can I restrict which MCP tools Copilot can access?
Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.
Does MCP work in VS Code Remote or Codespaces?
Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
MCP tools not available
Ensure you are in Agent mode in Copilot Chat. MCP tools only appear in Agent mode.
