Signals available

Visible usage signals are shown for discovery only, not as proof of safety.

Best for

Backblaze B2 users who want AI-assisted object-storage operations with a deliberately scoped B2 application key.

Not ideal for

Organizations that require a long operational track record before allowing AI access to production object storage.

Avoid if

Do not use an all-access B2 application key when a bucket/prefix/capability-scoped key is sufficient.

Trade-offs

Promising signal, but it ranks below the current Recommended/Shortlist admission cohort on maturity, uniqueness, publisher trust, security clarity, or MCP-native evidence.

Evidence-backed setup

Install & Agents

Choose your MCP client. A client connects to the MCP server; the language model is selected inside that client. Only stored, source-backed configurations are shown.

Claude Desktop

Transport not recorded

Publisher documented

Launch with `npx -y @backblaze-labs/b2-mcp`.

The publisher provides client-specific setup instructions.

Verify safely: Verify the client establishes an MCP session and can enumerate the server's advertised capabilities before any high-impact action.

Uninstall and revoke

Remove or disable this MCP server entry from the client configuration; revoke OAuth/API credentials when the connection created or used dedicated credentials.

Evidence & methodology

Publisher-documented setup is not the same as MCP100 execution testing. “MCP100 logic checked” means the stored configuration shape was reviewed, not that third-party MCP software was run.

Reviewed access

Access & risk

Review the exact access boundary before connecting this MCP to accounts, credentials, or sensitive data.

Authentication: Backblaze B2 application key/credentials as documented by the official server.
Permissions: Exactly bounded by the connected B2 application key's capabilities, buckets and prefixes; broad keys can enable high-impact object mutation/deletion.
Data handling: Object names/content and storage metadata requested through tools can be shared with the AI client/provider.
Cost: Backblaze B2 storage, download/API transaction and model/provider pricing applies.
Risk and cautions: Object-storage mutation/deletion authority must be tightly scoped, and the server has only a few days of production history.
