Read-only S3/MinIO/R2 object storage for AI agents — list buckets/objects, metadata, fetch.

VerifiedSTDIODesktop onlyFiles & Storage

Overview

AI-generated overview

Read-only S3-compatible object storage access for AI assistants: list buckets and objects, inspect metadata, and fetch objects from S3, MinIO or R2.

What you can do
  • List buckets and objects in S3-compatible storage
  • Inspect object metadata
  • Fetch object contents for the assistant to read
  • Works against S3, MinIO and Cloudflare R2 endpoints
  • Read-only: no upload, overwrite or delete operations are described
When to use it
Useful when an assistant needs to look at files stored in S3, MinIO or R2 — for example to browse a bucket, check object metadata, or pull a document into the conversation — without granting write access.
Requirements
Runs locally as an npm package over stdio, so Node.js and a desktop MCP client are needed. The manifest declares no environment variables, headers or authentication, so connection details and credentials for the storage endpoint are not documented here and must be confirmed before use.
Before you install
It reaches your object storage, so whatever credentials it uses should be scoped to read-only access on the buckets you intend to expose. The manifest declares no authentication settings, so verify how the endpoint and keys are supplied. Object contents fetched by the assistant are passed into the model context.

Installation

In SourceWeft

  1. Open Mcp S3 in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
