How to Use the Backblaze B2 MCP in Claude Code

Q: How can a developer add the Backblaze B2 MCP Server to Claude Code?

Typing claude mcp add --transport http backblaze-b2 -- in your terminal registers the Backblaze B2 MCP Server. Once registered, the server configuration allows Claude Code to access your Backblaze B2 buckets.

Q: Describe how Claude Code resolves regional API endpoints for Backblaze B2.

Invoking authorizeaccount allows Claude Code to fetch your Backblaze B2 account's dynamically assigned API URL. Subsequent Backblaze B2 file and bucket operations route through this regional endpoint automatically inside Claude Code.

Q: Explain the outcome if Claude Code attempts to delete a Backblaze B2 bucket that still has files?

An intentional 400 error occurs via deletebucket, which Claude Code reads instantly. Claude Code immediately alerts you in the terminal and offers to list the remaining Backblaze B2 files so you can clear them.

Run Claude Code to script Backblaze B2 bucket creation, audit file versions, and prune dead storage nodes directly from your terminal.

Terminal-Driven Backblaze B2 Bucket Management

Directly calling `list_buckets` outputs your Backblaze B2 storage partitions straight to your Claude Code shell. Piping this Backblaze B2 data into other command-line utilities lets you verify active cloud configurations instantly.

Audit Cloud Files via Claude Code MCP Server

Since `list_file_names` searches your Backblaze B2 buckets for specific PDF or MP4 files inside Claude Code, you bypass browser consoles completely. Claude Code filters out shadowed states to show you exactly what is taking up space on your Backblaze B2 disk arrays.

Purge Redundant File Versions and Stalled Uploads

As `delete_file_version` targets specific Backblaze B2 storage footprints to vaporize chunk data headlessly in Claude Code, you clean up storage blocks instantly. Accumulating old file versions drives up your Backblaze B2 hosting costs, which this Claude Code workflow prevents.
