Frequently asked questions

What runtime or dependencies are required?

Docker is required to run the pre-built image or to build the server from source. AWS credentials must be provided via environment variables.

How are AWS credentials supplied?

Credentials are passed as `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, and `AWS_REGION` environment variables when running the container.

Where does the data live?

All data operations are performed directly on Amazon S3. The server itself does not store any persistent data.

What transports are supported?

The server uses standard input/output (stdio) communication, as typical for MCP servers run via Docker.

Is the server authenticated?

Authentication is handled via the provided AWS credentials, not through a separate MCP-level auth mechanism.
