Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.
Your AI does the work. We keep it safe and sound.
No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.
Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

Each Connector runs inside its own sealed environment.
Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.
One switch stops every agent. Instantly.
One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.
Spending limits that pause instead of surprise.
Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.
Three controls, built into the layer your AI connects through.
Curated set · 10 capabilities
We ship only the actions that matter.
01-04
4 capabilities in this set.
Part of 10 available through Backblaze B2.
- 01
Get file info
Obtain granular checksum and headers associated with one precise B2 File
- 02
List buckets
Crucial to resolve immutable String Bucket IDs prerequisite to executing downstream CRUD operations strictly inside native borders. Retrieve the exact Storage Buckets existing globally on the B2 Account
- 03
Create bucket
Bootstraps essential structures before assigning automated backup syncs overriding file lock retention bounds. Provision a fresh logical Storage Bucket partition
- 04
Delete file version
Instantly removes the storage footprint avoiding long-term retention hoarding. Irreversibly vaporize specific absolute chunk data from disk arrays
05-07
3 capabilities in this set.
Part of 10 available through Backblaze B2.
- 05
Hide file
Does not actually delete binary payload, merely injects a null-marker shadowing the actual file ensuring b2_list_file_names ignores it, enforcing safe soft deletion logic. Mark an active B2 file as hidden leaving data for lifecycle sweep
- 06
Authorize account
Uncovers the dynamically assigned apiUrl (e.g. api003.backblazeb2.com) natively orchestrating regional data ingress specifically assigned to your billing account. Verify and extract Backblaze globalThis session routing endpoints
- 07
Delete bucket
Fails intentionally via 400 Bad Request if standard files or hidden object versions persist nested inside. Ensure all lifecycle rules completed purging prior to command. Irreversibly delete an entirely empty Backblaze Storage Bucket
08-10
3 capabilities in this set.
Part of 10 available through Backblaze B2.
- 08
List file names
Examines precise .pdf, .mp4 file locations avoiding hidden shadowed states produced by lifecycle overwrite semantics. Paginate primary surface-level object metadata from a specific Bucket
- 09
List unfinished large files
Crucial for verifying broken API pipelines originating from external S3 clients failing CompleteMultipartUpload. Scan B2 nodes for stalled Multipart Upload chunk aggregates
- 10
Update bucket
Use only for static asset endpoints. Mutate globalThis ACL privacy settings for a bounded Bucket
Real work
What teams actually run
Compliance Cleanup
A system administrator needs to remove all old, unused file versions from a bucket to meet retention policies. The AI uses the delete_file_version capability.
New Asset Deployment
A developer needs a new, private bucket for staging assets. The AI provisions the bucket and sets its privacy rules.
Debugging Uploads
A data pipeline fails mid-transfer. The AI checks for stalled multipart uploads using list_unfinished_large_files to pinpoint the failure point.
Security Audit
You need to confirm which buckets are public and which are private. The AI lists all buckets and checks their current access rules.
Automate a task

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.
One connector, every AI
Backblaze B2 works with the most popular AI clients.
These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Backblaze B2, so you can see the experience inside your AI.
It does not authenticate your account with Backblaze B2. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for
Built for the work Backblaze B2 owners hand off.
This MCP is essential for engineers and system administrators who manage large, complex data sets. If your job involves maintaining cloud infrastructure, auditing data integrity, or building robust backend services, this connector gives your AI agent the hands-on control you need.
- 01
DevOps Engineers
Use it to rapidly verify bucket states, clean up abandoned file versions, and debug failed multipart streams.
- 02
Backend Developers
It lets you create public and private storage domains directly from your development environment.
- 03
System Administrators
You can audit the object footprint and perform granular file integrity checks across your entire storage system.
FAQ
Questions Backblaze B2 owners ask.
- 01
Is this MCP compatible with S3-like services?
Yes. This MCP manages Backblaze B2, which is highly compatible with S3 standards. It gives you the control needed for object storage management.
- 02
Can I delete a bucket if there are files inside?
No. The delete_bucket capability requires the bucket to be completely empty. You must ensure all files and versions are purged first.
- 03
What is the difference between hiding and deleting a file?
Hiding a file (soft delete) marks it so it's ignored by standard listings, but the data remains for recovery. Deleting a file version removes the data permanently.
- 04
Does this MCP help with large file transfers?
Yes. It includes a function to list unfinished large files, which is crucial for diagnosing broken multipart upload streams.
- 05
Do I need to manually run commands for every task?
No. Once connected, your AI agent handles the complex API calls. You just need to tell it what you want to achieve in natural language.
- 06
Can my AI agent debug broken uploads in Backblaze B2?
Yes. Ask your agent to list unfinished large files. It detects multipart upload shards that disconnected before completion, which consume billing quota. It provides granular visibility so you can safely clear dead streams via API.
- 07
Can the agent make my private bucket publicly accessible to serve CDN assets?
Yes. If commanded, the agent can update the bucket privacy setting from 'allPrivate' to 'allPublic'. This instantly routes objects to be fetched securely using friendly URLs for front-end hosting or CDN origins.
- 08
How does the agent handle file deletion safely using B2 protocol?
The agent can perform both soft deletes (hide file marker, triggering lifecycle purge later) or absolute hard version deletes. If you tell the agent to 'hide the file', the file remains physically safe but vanishes from directory listings.
