Amazon S3 Bucket MCP Server for Claude CodeGive Claude Code instant access to 7 tools to Delete Object, Get Bucket Acl, Get Bucket Policy, and more

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.

Claude Code registers Amazon S3 Bucket as an MCP server in a single terminal command. Once connected, Claude Code discovers all 7 tools at runtime and can call them headlessly. ideal for CI/CD pipelines, cron jobs, and automated workflows where Amazon S3 Bucket data drives decisions without human intervention.

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

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

The Amazon S3 Bucket MCP Server exposes 7 tools through the Vinkius. Connect it to Claude Code in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
