Connect Claude Code

Add quickS3 to Claude Code as a remote MCP server with one command, sign in, and pick the roles it gets. Then check what it can and can't reach.

Owner Admin Member AI user

You need Claude Code installed and at least one custom role in your quickS3 organisation.

  1. Add the server from your terminal:

    claude mcp add --transport http quicks3 https://quicks3.com/mcp

    The AI agents page in quickS3 shows the same command with a Copy button.

  2. In Claude Code, run /mcp, pick quicks3, and sign in when your browser opens.

  3. On the consent page, untick the roles Claude Code doesn’t need, pick how long the access lasts, and select Authorize. Approve an AI client explains each part.

  4. Back in Claude Code, try it out: “List my quickS3 connections and the buckets on each.”

Claude Code can move files as well as list them, because it can run curl to follow the download and upload links quickS3 gives it. Ask it something like “Download reports/2026/q1.pdf from the finance bucket into this folder.”

Check it worked

Open AI agents in quickS3. Claude Code appears under Connected clients as Active, and Last used updates after its first request.

Disconnect

Select Revoke next to it on the AI agents page. That stops it straight away. To also remove the server from Claude Code, run:

claude mcp remove quicks3

If /mcp later says authentication failed, the access has probably expired or been revoked. Run /mcp again and sign in to approve it afresh. More fixes in troubleshoot AI clients.
