Model Context Protocol server for AWS S3 operations
Model Context Protocol server for AWS S3 operations
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.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
list_buckets — List all S3 buckets in the accountcreate_bucket — Create a new S3 bucketdelete_bucket — Delete an empty S3 bucketlist_objects — List objects in a bucket (with optional prefix filter)upload_object — Upload a file or string content to a bucketdownload_object — Download an object from a bucketdelete_object — Delete an object from a bucketget_bucket_policy — Get the policy attached to a bucketset_bucket_policy — Set or update a bucket policyCompare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
